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 🙂
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
- 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.
