Sega Saturn Mod Chip Installation Guide

I’ve had a handful of people asking me for a good set of intstruction on how to install the Sega Saturn mod chips that I sell.

I’m not responsible for any damage you may do to your Saturn by performing this modification. There isn’t much to worry about, but I just don’t want anybody mad at me ๐Ÿ™‚

Thanks to Jess Ragan for his help in creating this guide!

What You Need

  • A model 2 (32-pin – usually round-buttoned) Saturn
  • One Saturn mod chip
  • A soldering iron (here’s a new-to-soldering guide)
  • Possibly some extra wire (see step #2)
  • Transparent tape/Scotch tape
  • Scissors
  • Phillips head screwdriver with a long thin neck that can reach the Saturn’s case screws.
  • A copy of a Saturn game for testing purposes.
  • A nail file or something similar (may only need this if chip does not fit snugly)
Step 1 – Preparation
  • Keep your chip safe by leaving it in the anti-static bag that I ship them in.
  • Unplug your Saturn
  • Turn your Saturn upside down on a table
  • Remove the Saturn’s case screws
  • Put the screws in a safe place
  • Turn the Saturn right side up.

Step 2 – Install Chip and Hook-up Lens Cable

  • Look at the twisted white ribbon cable running from the center of the system to the shiny metal box on the right hand side.
  • Part of the ribbon will be taped to this metal box.
  • First peel the tape off the metal box, then gently unplug the right end of the ribbon cable.
  • Take this end of the cable and plug it into the connector on the modchip as pointed out below.
  • Plug the chip itself into the plug where the lens cable was.
  • If the chip does not plug in easily, you may need to file down the side edges of the plug in order to give it a better fit.

Step 3 – Getting Link Cables Layed Out

  • Below you can see the linking (soldering) points of the two cables from the IC chip towards the motherboad.
  • You can also see how the lens cable is to hooked up to the chip.
  • A close-up shot of both solder points follows in the next steps.
  • You may need to add some extra wire to extend the link cables’ reach across the machine.

Step 4 – Connect the Power Link Cable
  • The small wire soldered into the left side of the mod chip is called a jumper cable
  • Attach this jumper cable to the Saturn to power the chip
  • On the left side of the Saturn, there are four metal pins in a vertical row
  • Take the end of the jumper cable and plug it into the second pin from the top (on the back of the unit) even if you see 5 pins instead of 4. (It’s the one marked 5VA — if one does not work, try the other).
  • Below is a close-up of where to solder the power cable (red)
  • Please note the power wire MUST solder to the power socket directly!

Step 5 – Connect the Signal Link Cable
There are two ways to do this step:

  • The original way was to solder the signal (blue) wire to pin 14 of the 32-pin chip.
  • To make this easier, put 2 pieces of thin cardboard surrounding and isolated the 14th pin
  • Then you soldered to the 14th pin very easily, ignoring the other pins
  • Below is close-up of where to solder the Signal cable (blue)


  • You can get rid of the signal cable altogether and link the signal point to point B with a bit of solder instead of linking to pin 14 of the 32-pin chip.
  • This experiment has been detailed at this thread at SegaXtreme

Step 6: Finishing Up

  • Take a few pieces of tape and lay them over the ribbon that’s hanging over the chip
  • Tape it down onto the shiny metal box so the ribbon and tape hold the chip in place.
  • Secure the ribbon with a few more pieces of tape, because you never can be too sure.
  • Before you put the case back onto the Saturn, make sure everything is ready to run.
  • Are the connections tight?
  • Is the mod chip taped down well?
  • Once everything looks good, re-assemble your Saturn case.


  • Set your Saturn back up, plug in the controllers
  • hook it up to your television set
  • Put a burned backup CD into the Saturn and turn the system on
  • The disc should play just like a real Saturn game.
  • If not, you’ll need to open the Saturn again and see what you did wrong.

    Need some help with troubleshooting. I Installed a mod chip a while ago but now my Saturn has stopped working. It goes straight to the Bios(?) screen and says “checking disc format…” but the laser does not move. On startup rather than beginning with the black screen where the many pieces fly together to form the Saturn symbol, it
    loads right into the silver Saturn screen with the date at the bottom. I’d like to know if there is something wrong with the chip, ie loose wire or something non-chip related…

    Any help is greatly appreciated.

    Hopefully that will be a help to you ๐Ÿ™‚

  4. msimplay says:

    thank you Racketboy i bought my modchip from you and installed it on my Japanese Sega Saturn. I installed it right however i did have trouble pushing the chip into the saturns cd pin out. It didn’t work at all until i did that. But now its working and it feels damn good coz i got a load of backups that i had to use swap trick with in the past

  5. MisterKreK says:

    Howdy, Man!
    The modchip arrived OK here in Brazil!
    Just a tip: the A< ->B jumper to substitute the “blue” connection to pin 14 have not worked in TecToy’s brazilian Saturn. All Sega products are reassembled and sold here by TecToy. It’s a “model 2”, with a 21 way flat, 32 pins chip and round buttons, but needed the wire from “A” to “pin 14” to work. No happy A-B jumper here.
    Thank You for sending it so quickly!

  6. OrMuZ says:

    Hi Racketboy,

    Great job this little modchip.
    I’ve just received it (7 days for transatlantic shipment), installed it and unleashed the Saturn’s capabilities to read CD-R.

    One thing that may help some of the future modders : the chip needs to be deeply input in the slot. Failure to ensure it’s gone all the way down into the slot will prevent any game from working. (message “verifying disk format” will display and disappear)

  7. Anonymous says:

    Do I need to solder the power link cable or can I just place it where it belongs?

  8. racketboy says:

    It’s possible to just wedge it in place, but it will be more secure and reliable if you solder it.

  9. Sixteenbars says:

    First and foremost I wanted to say thanks to Racketboy for a VERY fast shipping turnaround.. Also When I got my mod chip I couldnt get it to work at all,.. Cd’s Would not spin (originals + Cdrs). I thought it might be the A – B connection so I tried the pin connection.. Same result. So I emailed Racketboy and gave em the low down on the problem.. (BTW – the chip was in all the way) He then told me send the chip back and he’d send me a new one.. Sure enough I did, he did, and it works like a charm.. Although I didnt get to try the A – B method again because I clipped the wires from the chip so I didn’t have to solder them to the board again.. Anyways thanks for the fast, customer satisfatory service!

    – Highly Recommended

  10. NHJ says:

    i bought some chips from racketboy and a cartidge, i have to say the shipping is extremely fast, four days to arrive to belgium!

    i modded the chip in order to make it work in my jap grey saturn, guess what, it works ๐Ÿ˜€ , it’s a six years of wait that’s over.

    thanks to you for selling those chips.

    You should advertise more the fact they can be modded to run on 20 pins saturn, you should even as the mod is not for begginer sell already modded chips.

    that’s my thoughts.
    keep up the good work

  11. Anonymous says:

    these instructions are a bit dated.. It’s been found that you can just bridge A and B on the modchip with solder, and just connect the red wire to the 5V and you’re done.
    There’s no need for a signal wire.

  12. danholo says:

    Hi! I just got a white, round-buttoned JP Sega Saturn, and I was wondering if the mod-chip and above installation instructions would work on my machine. Thanks!

  13. racketboy says:

    If the insides looks like the one in the picture, you’re all set. The region/color of the Saturn doesn’t make a difference.


  14. Ben says:


    Extremely fast postage, thanks.

    Can i bridge points A>B instead on a PAL system? As someone mentioned to me that it does’nt always work??? I was gonna bridge em’ to make it a bit neater in my saturn.

    Thanks Racketboy

  15. racketboy says:

    the region shouldn’t matter, but yes.
    In most cases the A+B method will work

  16. Giovanni says:

    Hi racketboy!modchip is arrived!just 7 days and it’s in italy!wonderful transation

  17. Flojo says:

    Finally … our houseguests left and I was able to install my Saturn chip this morning. First in the slot was TEMPEST 2000. It was great playing this old favorite without the cheesy old Atari Jaguar.

    Installation notes:
    1. This was EASY!

    2. Soldering is a good idea, but if you don’t have the confidence or just don’t want to hassle with it, you can get away with sticky tape!

    3. The signal wire can be looped right back into the B slot and taped in place.

    4. The power line can be stuck into the power supply without solder if you’re going to be gentle with your system or don’t mind opening it up again if it comes loose.

    5. Filing down the sides of the chip to loosen the fit into the motherboard slot was key for me.

    Thanks to Racketboy for making this so painless and fun!

  18. Ivo says:

    I installed a modchip without much hassle, using the A+B method.

    Thanks to racketboy for selling them at a good price and providing the excellent guide and troubleshooting (although I haven’t required that)

    As I didn’t know how to solder I had a friend supervising me. I’ll just like to highlight the tricky parts of the process as far as I was concerned

    1. soldering the power cable can be a bit tricky, as the contact is in the plastic square which is harder to reach with the soldering iron (for someone inexperienced, at least)

    2. fitting the chip was hard. I guess this is why there is the advice of “filing” the edges for an easier fit. I wasn’t sure of where I was supposed to be able to file without damaging anything (maybe that part could be clearer in the guide?) so I just plugged it in eventually. It had to be pushed in with some force, and if you don’t do it properly (with care not to bend it) I can imagine one could snap it in this part of the fitting process, so be careful.

  19. Anonymous says:

    installation was pretty easy, i didnt even sodder, i used the A to B method and just inserted the wire from point A into the hole in the circuit board at point B and wrapped a little (1/4 inch) of the wire over board to keep it in place, and the power wire i simply wedge it in nice and secure to soldering at all, only difference i notice is that it takes slightly longer for games to boot. thanks racketboy.

  20. Anonymous says:

    hey, i had a quick question.

    my power link cable came loose from the modchip, i was wondering how to reattach it. Do i need to solder it back on?


  21. racketboy says:

    yup, just solder it back into place.
    best of luck.

    BTW, feel free to join the forums and post in the technical help section for quicker help

  22. PuureChaos says:

    For some strange reason, the mod in mine has to be mounted backwards, so that the laser cable faces towards the outside of the case, and the cable needs to mounted upside down. Its the only setup where the laser will actually move. And the Saturn still goes straight to the audio screen. It won’t play any games, CD-R or proper Saturn games. Any thoughts anyone?

    i bought the chip from racketboy
    and it took a week to get to me
    in the uk scotland.packaging was
    good and the chip works great tho
    i did have problems with my saturn to begin with.i bought a model 2 saturn but the power supply and cd drive were the same as a model1 saturn but i found a good tutorial
    on my version of saturn and followed it and also done the a+b
    wire setup and all works perfect.

    thank you racketboy’s the link for my saturn version wich is 64pin version.

  24. Zachism says:

    Just received my modchip in the mail today, very fast shipping. Time to install!

  25. Anonymous says:

    Mod chip and memory card showed up today installed the chip (no soldering yet) and started testing it. It runs great and the memory card now lets me play my X-men vs street fighter game. Super fast shipping bought the chip on Friday had it by Monday.

  26. s00pcan says:

    Installing for a friend, I’m getting the “disc unsuitable for this system error”, too bad he didn’t give me any real games to rule out problems with.

  27. racketboy says:

    Sounds like they are imports that need to be patched.

    Great chip, fast shipping. Only had to solder the power wire and make a solder bridge between points A and B. The red power wire was a little bit short, but still reached.

  29. Anonymous says:

    Hey, Got my chip installing on a model 2 32pin. I got everything in and used the A+B method, soldered at the power point. But when I tried to fire her up afterwards the drive motor would not spin, and even if there was nothing in the drive it said checking disc. After checking for snug connections i noticed the drive open indicator position did not matter it still did it. Long story short 10 mins later I resoldered the A-B connection, and vwalla everything works great. My advice to anyone doing this method is to completely unsolder the wire the comes on the chip and drop a bead bridge between the two for the best connection.

    Just got my Saturn Mod chip.

    I had two failures before getting it successfully working, but that was just difficulties getting the cd cable passthrough properly plugged in. I very slightly filed the edges of the connector and tried again, and it’s all up and running.

    I used the A->B bridge technique, on a model 2 Saturn which works great so far. For a hardware mod chip, this was about as painless of an install as I think you can get.

    Looks like my Saturn is back in business! Very cool.

    Wass Up Racket Boy, I got your chip in today. It took about three day’s, not including new years day, and the day after. I quickly got it working in about 2 hours. I wish the directions would be a little clearer though. I did everything in the guide, but could’nt get it to work. I then looked over the guide a bit more, and in the picture, which I could hardly see, that there were 3 pins,were the wires were going into. I was doing the A + B method. What I did was solder the power wire, over the middle connection then into the signal wire. I soldered all three in to it. I then diagnosed the problem by doing it all over again, reconnecting everything, and doing the soldering again. But I had to Desolder the 3 braids and connect the power wire, then the a+b method solder. Everything is good to go. I almost thought is wasnt working, because I put in a downloaded ISO,and it said “Game Disc Unsuitable for this system.” Then I figured it was a japanese game and did’nt patch the iso. But I quickly burned my U.S Game and it boots FLAWLESSLY NOW.

    Directions I Did.(Model 2)
    1) Take out 5 Screws underneath Saturn.
    2) Lift out top, and Disconnect Ribbon Cables for drive, and ground yourself.
    3)On the chip, desolder the signal wire, and save it. Connect the middle tab to the signal tab with solder.
    4) Shave off sides with scissor, the sides that goes into the old ribbon cable.
    5) Plug CD Ribbon cable to modchip, then into the Mother Board.
    6) Use the extra signal wire and solder it to the end of the power wire. It’s a little to short, and if installed with tension my come out over time. So I just used the signal wire and soldered it the the 5 volt cable.
    7) Check to see if it works, and put back case and screws.

    P.S. Racket Boy, Could I buy the complete U.S. Saturn Game Set?

    For any other Australians:

    I bought the mod chip from Racketboy, and have now got it working on an Australian Saturn.

    Saturn: MK-80200A-03 (32pin model 2 equiv)

    I initially soldered the signal line to pin 14, but this didn’t work at all (CD spindle didn’t power up and start spinning). I found that when I switched to the (simpler) A+B method it all worked perfectly!


    (most trouble I had was discovering that the Australian Saturn is set to Europe region – was expecting the east asian one…)

  34. Kurt Ohboy says:


    I just received my Sega Saturn that I got from eBay (model 2). I had my chip for a few days now so today was the day! I followed all instructions I could find here, then I decided to try it. (Btw, I used the 14 pin method using scotch tape only) When I saw that the Saturn animation didnโ€™t showed anymore, I knew there was something wrong. I tried many things for a few hours, then I thought that there was probably a power problem. I finally got to put the red wire in its place carefully. Then I started my Saturn again, the animation was back! My brother was totally skeptical about all that. I told him: โ€œBelieve me, itโ€™s gonna work!โ€ So I patched Radiant Silvergun then burned it. You know what? It works!!! Everything is just fine! Thank you RacketBoy! I know absolutely nothing about electronics and I managed to mod my Saturn so believe me, anyone can!

    Thanks a lot!

    – Kurt Ohboy

  35. Blatt says:

    Great mod, fantastic instructions. I soldered to the 14th pin (I couldn’t get the loop option work). Everything works great. Thanks for being the last option out there ๐Ÿ™‚ Now we just need these kind of instructions for the NES 2 a/v mod!!!

  36. Dan says:

    Hey there I want to buy a Satmod I live in Mexico who buy?

  37. beano says:

    Have you any plans to get the Saturn mod chips back in Racketboy? If not does anyone know where a UK gamer and Shining Force 3 lover might find one or a pre-modded Saturn?

  38. racketboy says:

    There is a possibility, but I can’t make any promises.

  39. cdogw says:

    Thanks Racketboy for the ultra-fast shipping! Some things I noticed in the progress of installing the chip:
    1. Since I had a 64-pin chip instead of the 32-pin chip on the motherboard, I used the A-B method, just melting the solder already on the contact B and connecting the black wire to it.
    2. First time I checked it, I put the mod chip in backwards. 2nd time, I had the lens cable in backwards. Then it worked.
    3. It works, but in a weird way. CD-R and real game both boot into the cd-player. After hitting ‘play’ when the songs of the disc appear, I hit reset and the system boots into the game. A little more intricate than I would have liked, but can’t really complain. Guardian Heroes works great.

  40. Jeremy s says:

    Hey racketboy. Do you have more Saturn Modchips. I would like to buy one more, and pick up another model 2 saturn. How much would you like for 1 more chip and the set of Saturn ISO’s? Please racketboy.
    Email me at

  41. Silviu says:

    hey racketboy,

    i bought one of your chips a while ago but couldn’t get it working. its a 32 pin pal saturn and i connected the A & B points together.
    the weird thing is that with the chip installed not even originals boot. it only enters the menu where i can play the music that’s on the cd (original or backup).
    any idea whats wrong?

  42. Rob says:

    hey racketboy, I was wanting to purchase a modchip, but it says in the comments here you might not have any, but it also says in the page for the modchip that they are in stock… sooo? I was willing to pay for one tonight

  43. racketboy says:

    Silviu, have you gone through the suggestions in the troubleshooting page?

    Rob, yes, I have some at this moment.
    Thanks for your interest!

  44. Rob says:

    awesome, ordered one anyway this morning before i read this, can’t wait to put the baby in!

  45. remay says:

    I think I’ll buy one when I get paid.

    Hey Racketboy, do you know how I can get Rocketbeetle (from the forums)’s attention. He’s never on the forums and I need to know more about that switch he installed on the saturn. Like what kind of switch do I need and where do I get it?

  46. michael says:

    hi, do you still have modchip in stock?

  47. Dan says:

    Just wanted to let you know I got my modchip yesterday and installed it last night in my Model 2 system. Installation was a breeze, even with what little soldering skill I have. Got a solder line from A->B, had to trim the excess board on either side of the mobo connector of the chip to get it to fit. The power lead was plenty long so there were no worries with that. Worked right away.

  48. fj4 says:

    Thanks! The chip works flawlessly. The power wire was a little too short, but who cares?
    If this was eBay feedback I’d have to say “A+ seller, will buy again!”

  49. anon says:

    does this work on a model 1 pal uk saturn?

  50. racketboy says:

    Not a model 1, sorry…

  51. dan says:


    i bought a mod chip a few months ago, and unfortunately couldn’t test it right away due to buying a Saturn that was shot. So i finally got one yesterday, and tested it out, and i can’t seem to get backups running. I’ve followed the tutorial to the letter and still am having trouble. Could the chip itself be bad? Can i ship it to you to test it?? Let me know. thanks,


  52. WyldRogue says:

    Just wondering if I can still purchase a modchip for my Saturn. I actually own both Models so making sure this site and chip is still available.

    Hope it is so that I can order a modchip for my Model 2. Will stop back frequently to see if I got a response.

  53. Ian says:

    Hey Racketboy,

    Just bought a model 2 saturn and was interested in buying a mod chip for it. Thanks.

  54. SupraGenius says:

    Awesome, pure awesome! Racketboy is very quick and responsive, and his mod chip works wonderfully! I can now stash my originals away for safekeeping! Thanks racketboy, I will try to buy more from you, though I don’t do ebay at the moment.

  55. Michael says:

    Good to see the latest date from pleased people was just a few weeks ago. Im planning to buy one and install over Christmas break…

    i have a segs saturn and it will not turn on do you have any idea what the problem may be

  57. chris says:

    i have a sega saturn and it will not turn on do you have any idea what the problem may be

  58. Chris says:

    Thankyou for the chip just brilliant works perfect. Installation was very easy besides trying to fit the chip into the cd lens slot on mobo just ued the blade of the scissors to trim down the sides for a perfect fit.

  59. Tim Duch says:

    I dont know which Saturn version I have. On the outside, it has round BLACK buttons; does that make a difference? I noticed the circuit board below the lens is a bit different, the 32 pin chip appears to be below the plastic part of the lens. Also, how big is the mod chip? From the pictures and from looking at my saturn it appears too big. If anyone could help me that would be great.

  60. Tim Duch says:

    i just ordered this and i forgot one thing, do the backup games you burn have to be burnt at a certain speed like 4x or something? because i have a dreamcast and i couldent get burnt games to run unless i burnt the games at 4x speed. i have img burn and it was burning some games at 10.1x speed, is that too fast or does it not matter? if someone could help that would b great

  61. racketboy says:

    For the Saturn, I usually do 4X or 8X.
    Best of luck!

  62. jmooch says:

    hey dawgs thanks racket for the mod.. i just have one question dudes, i burned a game using alcohol (sf3 US) and when i boot it up it plays only the music of the game in a cd player…



  63. Kevin says:

    Hi, can you tell me if this modchip will instal/work on a white *import* Saturn?

  64. Kevin says:

    Sorry by import I meant Japan…

  65. racketboy says:

    The region on the Saturn doesn’t matter — the main concern is what it looks like inside.

  66. Paul says:

    Hi got my chip today thanks but I can’t get it to work have hoked it up as shown in the guid and followed very carfully
    I have a model 2 saturn and am not new to the mod sece hace moded plenty of system in past but for some reason this will not work! With the chip in the saturn will not even spin up a disk no matter whats in there the lens will not fire anything but take it out an put the ribbon back on its own and it will work fine any ideas??

  67. Jason Briggs says:

    Thanks for the chip, works perfectly, just definitely could’ve used a smaller soldering tip than the only one I had at home. Now I can finally put the saturn back onto my shelf and play more than Space Hulk….

  68. Matthew Thorns says:

    Excellent Mod chip!
    Thank you so much for being one of the remainder USA Saturn mod chip venders. I appreciate the great response to my faulty chip problem, and the second chip worked flawlessly. It was a pleasure doing business with you and I hope you can satisfy Saturn fans for years to come.

    Just a notation: When putting solder from point A to B it helps a lot if it is done on both sides. For one reason or another I did it on one side and had no response from the system, but when I applied it to the other side it worked fine. Does it matter which side you solder points A and B together or was it probably just a bad connection on the first try?

  69. james kearns says:

    hello i live in the uk can you guys ship out a mod chip for me ? thanks

  70. racketboy says:

    Yup — I ship to the UK all the time ๐Ÿ™‚

  71. Tim McKernan says:

    Mod chip and Memory card came the other day. Memory card didn’t seem to work but then i recalled that the old memory card I had died assuming it was the card. I’m not convinced it is the Saturn. Also I have the 64 pin Saturn which means a lot of pain in the ass. If i cant extend the memory what is the point of getting to play a lot of games. I’m on the hunt for a model 2 Saturn now. Excellent service from Racket boy, some confusion with the payment but he was responsive and pleasent

  72. Tim McKernan says:

    Whoops I re-read what i typed. I should say I’m convinced it is the SATURN that is broken NOT the memory card from Racket boy.

  73. mach_six says:

    I have installed this on my Saturn w/ relative ease compared to Xbox, Wii, PSX and others and able to play those “games”. I have a question does a modchip exists that allows to play JAP games on a US saturn w/o the 4-1 in cart.

  74. racketboy says:

    Hi mach_six! Nope — there aren’t any chips to take care of regions, but you can patch the ISOs of your games before burning so you don’t need a 4-in-1.

    Easy and free ๐Ÿ™‚

  75. Rhounin says:

    Thanks Racketboy!

    Installed within 15 minutes flat, so far works perfect for all the backups I have for my Model 2 Saturn. A way better solution to the swapping disc. I recommend this chip to anyone , and its really easy to install.

    The shipping took about ten days, pretty good.

    P.S. you are going to have to slightly file down the terminal of the modchip to get it to fit, but other then that, its all game playing.

    Thank You

  76. Bizzle86 says:

    I just wanted to give a big THANK YOU to racketboy! Your tutorial was great and following everything to the T helped out. Whoever does this make SURE you really push that chip into the slot on the board! That messed me up for a bit and yes, bridging the A+B spots on the chip was much easier than adding a cable to that extremely small 14th pin.

    Thanks also for the quick shipping and service. If you sell anything else other than the chip and the RAM Expansion cart, I would buy from you. Great help!

  77. Leandro says:

    Iยดve just installed a modchip in my sanyo saturn console, the A+B method didnยดt work though, but Iยดve done the “A to 7th pin of the sanyo chip” bridge and your chip worked flawlessly.
    Big Thank You.

    Hello racketboy,

    It has been a pleasure doing business with you and I am very satisfied with your communication throughout the transaction and how fast the mod chip arrived. The mod chip works great. If anyone is doing the signal wire method, I would suggest melting some solder on the end of the signal wire and then soldering it to the 14th pin because this way you don’t have to worry about holding the wire, solder, and soldering iron. It made it a lot easier for me anyway.

    I have a model 2 32 pin Sega Saturn. Installed the chip with the A-B bridge, and the cd-rom won’t spin up. I get checking disc and 2 green cubes. I read it could be a power problem. Is here another point I can soldier the power to on the chip?

  80. racketboy says:

    Have you tried soldering the signal wire to the chip instead of the A+B method?

    Dear Racketboy :

    I have received my mod chip just 3 days ago and I have not yet been able to get it to work. I have a 64 pin Model 2 US Saturn, so I followed this site’s instructions ( ).

    First time I tried the A+B method but seeing that wouldn’t do the trick I soldered the signal cable to the 8th pin in the 64 pin chip like pointed out on the instructions. I’m still getting the same results.

    Disk spins but lens does not attempt to read it like it should were the mod chip not installed ( I tried removing the mod chip and replugging the ribbon to see if my Saturn still worked that way and it did ) and Saturn goes directly to the music playing BIOS where I am able to play the music tracks of the game ( letting me know the device is able to read the disc when the mod chip is inside it ).

    What do you suggest me doing ?. Should I desolder the A+B bridge so that only one method is used ?

    I have already unplugged and replugged both the mod chip and the ribbon many times to make sure it’s not a matter of the chip not fitting in nice into the motherboard like many other users reported. I even filed down the end of the chip as other users suggested , but that didn’t help either.

    Thank you in advance,

    Sorry for what I said before, I was partially wrong.

    The modchip does work ! . Thing is, it works differently than I expected it to.

    I have to open and close the door trap for the game to be read and played , a bit annoying but at least the chip works fine.

    Thank you for the fast shipping ( around 2 weeks from US to Argentina ), great support and website.

    Saludos !

    Hi I just got mi modchip today, I have a question, the power cable goes on the pin or in the socket? the socket is the round tube that goes bellow of the pin line up?

  84. Hobie-wan says:

    A>B worked for me. If you look on the model 2 (8000A), pin 14 off that chip on the CD assembly goes to the bottom pin on the ribbon cable. On the modchip, the bottom pin from the ribbon goes to B.

    As for the power, I used a small “Y” splade, like you would stick on a wire and then use under a screw with a ground wire or such. I snipped off one branch so I just had one little thin blade. That slipped into the clip next to the post to tap the power fairly snugly. I shouldn’t have any issues with it slipping out and since A>B worked for me, my chip is easy to pop out if (when) I have to swap it into another Saturn. = ]

  85. omer says:

    No one seems to answer this very simple question. I have a Model 2 Sega Saturn (32pin) and I just ordered a mod chip from this website and I cant figure out where I need to solder the power wire to the power supply (5V). There is a socket with a round metal piece and inside the socket is a pin that is sticking up. Do i solder the power wire to the ruond metal piece or the metal pin that is sticking out in the 5V socket?

    Wanting to buy a model 2 jap saturn.Would like to know if you still sell the chips.And will it work on the white jap model 2 saturn?Thank you

  87. racketboy says:

    Yup — still selling them and it should work fine ๐Ÿ™‚

  88. pete says:

    just got my chip yeasterday had isssue with the power link had to re strip it but after that works like a charm thanks!

  89. Aaron says:

    I installed mine today in my Model 2. Works great. It didnt work at first, but I re-did all the soldering again and re-did the power wire to get it working. Thanks!

  90. Federico says:

    Hello Racket Boy, i have bought an Hitachi Hi-Saturn with a pre installed chip… it seems similar to the one installed on model 2, but there is only the red cable solded. At first the modchip worked but now it doesn’t. I also have some problems with the original discs. If i try to boot the sistem it only recognizes them as audio cds. So i have opened the saturn and booted an original cd and it works. When i put back the front on the console, it still recognizes them as audio cd… How can i do?

  91. Steve says:

    Had my chip for long while now but only just now had a chance to try it. Installed fine on my model 2 and loads originals perfectly but any copy I tried results in it not being read or loading.

    Sadly I only have one type of CD-R media on me at the moment (Sony Corp 97m24s16f) and don’t know what good type to get to try, any good brand I should get??

    Or is there a way to test to see if my chip is working perfectly without a working media??

    Thank you all

  92. zero says:

    Thanks a million for the chip. Good price, fast shipping, and it works great.

  93. RigorMortis says:

    I got my chip working using conductive glue rather than solder – seems easier and less expensive

  94. xen says:

    Hey, is the new red chip you’re selling the same as the one in the pics as far as functionality goes? I have a model 1, it’s very important to me that it does…

  95. racketboy says:

    Yeah, the functionality is exactly the same — color is just different ๐Ÿ™‚
    Thanks for your interest!
    But Model 1s can be trickier to install

  96. madmax says:

    Hey, Received the chip last week. I have 2 saturns both model 2 but 1 is the 32IC version and the other the 64IC. I installed the mod in the 32IC version. It did play original games but saw the backups as an audio cd. Tried the swap method and found that the backups are working fine so it must be the modchip. After some measuring i found out the power to the chip just wasn’t good enough. Restripped the power cable and resoldered it firmly on the +5v connector. Now it’s working like a charm.

    many thanks.

  97. tdc says:

    two things, the link to segaXtream forum links to the wrong thread, it goes to some void sticker on nba jam thread.
    second, i get the 404 page when i try to add the chip to my cart, are they no longer available?

  98. Mirror Messiah says:

    Hey, I have an oval button Saturn. Can this tutorial work on mine or are there major differences between generations? Does this mod chip enable region free play or just backup?

  99. racketboy says:

    Yeah, there is quite a difference between the models and I don’t typically recommend that you even bother with modding those oval-button units.
    But the chip is just for backups, but you can alter backups to change the region code.

    Just got my Saturn chip….super fast shipping, super easy instal (especially considering my first time using a soldering iron)…..thanks!

  101. verticalhilarity says:

    I bought racketboy’s mod chip, which came very quickly by mail. Installation was super easy even though I’ve never soldered anything in my life. I have a model-2 64 pin NTSC US Saturn.

    I removed the signal wire and soldered a bridge between points A and B then soldered the power cable to the appropriate point. I had to file the plastic of the chip down a bit to make an easy fit. At first I made the mistake of seating the chip with the optical cable connector facing the cd drive, which created the condition where no games, original or backup would be recognized. After switching the way the chip was seated it worked like a charm, although I have to open the cd lid and close again in order to get a “launch application” function to show up. All in all I am VERY pleased with the outcome, and what’s more – soldering is kinda FUN!! Thanks a bunch Racketboy!!

  102. Hi there, Racketboy! Please update your guide using this information:
    It worked great on my 64-pin model 2, even though I’ve got the disc-detection bug where you have to open the lid up and close it again. No biggie.

  103. D F says:

    For those who have had their chips stop working,
    mine did, after ~7 years of faithful service, and i found the cause was some _very_ fine breaks in the pcb near the ribbon cable connector, I soldered a couple wires to repair the damage, and it is working fine again ๐Ÿ™‚

    hope this can help someone else as well!
