How To Play Neo-Geo Games On Your DS with NeoDS

Over the last few months we’ve take a look at nesDS and Lameboy for excellent ways of playing NES and Gameboy games on our DS, but NeoDS has also arrived so we can play a number of impressive Neo-Geo games on our portable as well.

Special thanks to Ivo in writing the installation tutorial

Neo Geo Emulation Off To A Great Start

So far there, there is only one Neo-Geo emulator for the Nintendo DS, but it is quite impressive for such an early release.  Compatibility can be a bit hit-or-miss at this point (download the compatibility list for details), but it plays many games (including some newer titles) quite well.   In fact, I think the quality of the emulation will impress a lot of people.   Feel free to read this developer interview at GameSetWatch for more interesting details.

Installation Process

The NeoDS installation isn’t quite as easy as nesDS or Lameboy, but it’s not too bad if you follow the directions below.  The main things to remember are that everything needs to be in the root folder, ROMs need to be converted with the included utility, and you need the Neo Geo bios file included.

  • Download the emulator package at official NeoDS Google Group
  • Extract the compressed file contents into a folder using zip utiliy of your choice.
  • You will need to use a couple of files from the uncompressed folder – “NeoDS.nds” is the emulator itself, and there is also a tool “NeoDSConvert.exe” which you will need to use. There are detailed instructions in a “readme.txt” file (although if you follow these steps you probably won’t need to read it).
  • Get the Neo-Geo ROM files you want to use, in .zip format (this is similar to MAME). The system ROM is usually named “neogeo.zip” and is necessary to run the emulator, and any games that you want to play on the emulator (for example, Metal Slug is usually “mslug.zip”).
  • Convert ROMs to NeoDS’s special format. You will need to use the supplied tool “NeoDSConvert.exe”. Copy or move all the ROMs you want to use into a folder (including the system ROM). Then place “NeoDSConvert.exe” (copy or move it) to the same folder, like this:

Same folder

  • Execute “NeoDsConvert” (double click it). After a brief showing of the process through the command line, you will have a .neo file for each .zip you started with:

Converted

  • If you system ROM is not named “neogeo.neo”, you will need to rename it.
  • Copy or move “NeoDS.nds”, “neogeo.neo” and any other converted ROMs (in .neo format) to the root of the flash cart (it must be placed in the root).

Move

  • Then turn your DS, run the emulator, load any ROM (don’t bother running neogeo.neo though).

Video Tour of NeoDS

To get a better feel for how NeoDS handles, I’ve recorded a quick video that walks through some of the menus and shows a few games in action.

NeoDS’s Best Features

  • Decent compatibility, but runs a number of heavy duty-games quite well
  • Full speed for many games
  • Support for large games such as Fatal Fury: Mark of the Wolves and KOF 2003
  • M68000 cpu (cyclone), Z80 cpu (DrZ80), All forms of NeoGeo protection/encryption, Graphics, ADPCM audio, and PSG audio are all emulated
  • Ability to customize button mapping
  • Decent screen scalling
  • Closing the DS pauses and puts into sleep mode.
  • Able to switch between games easily
  • Ability to lower CPU speed (actually speeds some games up)

Complaints & Limitations

  • Some games just don’t run well right now — check compatibility list for details
  • No save states yet
  • FM audio, Raster effects, Memory Card, and Multiplayer are not yet emulated, but dev team is working on them
  • Dev team also admits that some timings are not accurate

    I used to play Metal Slug games on NGE on my PSP. I’m sure it would look better on the PSP than on the NDS. Thanks for this article, anyway.

  2. Jason Rioux says:

    great I will try it

  3. William says:

    Does it work for the M3 simply…I did all that steps mentioned but it does not load the roms…like it freezes…

  4. racketboy says:

    No clue — both Ivo and I run a CycloDS.
    I haven’t heard any complaints though so far on all the places I’ve dug around on.

  5. executioner says:

    Very impressive emulation!

  6. william says:

    It freezes on “guiSystemsInit complete Loading …” screen.

  7. william says:

    Can you guys post some converted games….I can’t seem so convert any others…except metal slug 1.

  8. Bastion says:

    Great for DS only owners but if you own both a DS and PSP, the PSP is sooo much better for emulation.

  9. rk says:

    I can only convert the neogeo.zip file. All others fail. What am I doing wrong?

  10. simon says:

    hi i have tryed to load your NeoDs020 and itloads up but the problem i am having is i have to use the patch file from a old vision and that converts the games and a green screen loads up but the i get error70 or 80 please can u do a step by step video to help me thanks

  11. racketboy says:

    Sorry guys — not sure what you’re doing wrong. I just followed Ivo’s steps above and it worked fine for me. If you have problems, I recommend asking on the developer’s site.

  12. Andrew says:

    Managed to convert the bios but not the games. Getting fed up. need some help

  13. light yagama says:

  15. racketboy says:

  16. Keiichi says:

    Doesn’t seem to work with some versions of Neo-Geo games – specifically, the ones I have that work just fine in NeoRAGE X…

  17. tex says:

    noobs… get the mame roms… try rom world…

  18. Keiichi says:

    No need for that Tex; I didn’t feckin’ know, did I…

  19. noobman says:

    umm..noob here, neogeo.zip is the only thing that seems to be converted. i downloaded an svcchaos and kof2003 roms(checked them out-they have “-bin”s in them not “-rom”s) and they dont get converted into a .neo file

  20. Kudret says:

    decent.., i followed your steps and instead of Metal slug i downloaded Street figthter 3rd strike and when i click on the convert exe. the black window came up but nothing was created, suggestions?

  21. racketboy says:

    Third Strike isn’t a Neo-Geo game — that’s probably the problem….

  22. Mr. Cee says:

    Thats cool..
    Nice to see the Neo getting love.
    I got the Neo on the psp and i play it
    more then actual psp games..

  23. Grappler Baki says:

    For some reason i get a black screen everytime i try to load a rom. any suggestions?

  24. meteoro2403 says:

    hi..i did all you said step by step but i can convert the neogeo.zip but not the others…by the way all files in the folder of kof2002 are bin..so i dont know whats wrong…coud you sent the game converted of kof2003 to my mail…please because i really need to play that game please only that game…fenix_gs12@hotmail.com

  25. MarcoRossi101 says:

    ok guys i have a solution to why ONLY The NEo bios gets converted.
    you have to go to a website that actually has NEO GEO roms.
    DONT SELECT THE MAME ROMS they wont work during conversion.

    heres a link i know for people who want Metal Slug

    http://www.coolrom.com/roms/neogeo/m/

    for those who want KOF check the same site on the same page. just look for The K Section.

  26. MarcoRossi101 says:

    never mind…. it wont work either =(

  27. jasonaccel says:

    does it work for edge ds?

  28. Seth says:

    “does it work for edge ds?”

  33. yoyo1899 says:

    it won’t convert the rom. only the neogeo.neo file. What should I do???? please reply

  34. yoyo1899 says:

    also, I have a DSTT Card

  35. Jonah says:

    Press on my name ,i can give you the coverted file which i just convert

  36. racketboy's Mom says:

    What is a bio supposed to look like and I have a neogeo20 zip folder but not a neogeo.zip as described? and I am also confused on how the converter is supposed to work.

    please someone be more clear for the dummies/nubbies

  37. Mix Master says:

    The problem you guys are having is using zip files in ROM format. You need to use NEO-GEO games/ROMS from the MAME list, which are in BIN format.

  38. Rokuken says:

    Wait a minute. So what you’re trying to say is that we need to download the games from the MAME section? If that’s the case, then this is not a Neo Geo emulator, this is a MAME emulator. Unless the only games that can be played are Neo Geo related ones.

  39. Rokuken says:

    Oh! Looks like that was the problem. Just like “Mix Master” said above:

    -Quote = [The problem you guys are having is using zip files in ROM format. You need to use NEO-GEO games/ROMS from the MAME list, which are in BIN format.]End Quote

    What people need to do is go to a website where you can download MAME roms,download the NeoGeo related ones, put them all in the “NeoDSConvert” folder along with the BIOS which is “neogeo.zip” (Search it in Google, it’s pretty easy to find), and run “NeoDSConvert.exe”. If it worked, the games will be converted to the format “.neo”. Some games just didn’t convert at all. For example, “Garou: Mark of the Wolfs” didn’t worked for me. I’m still looking for one that I can convert, but still no luck. Just keep looking for one that works, but remember you need to look for it as a MAME rom, not a NeoGeo rom. Well, that’s that. Hope this helps.

    thers no place to download it

  41. justauser says:

    If you google neods I found a download for it (not sure about linking in comments but the site was called “exophase”). One issue I came across with the converter software is the fact the neogeo bios needed a slight name change with one of its files (i have a mame.140u2 verified bios). The file sfix.sfix needed to be renamed to sfix.sfx. Once I did that, rezipped the files, the converter worked without issue (worked with pulstar and blazstar, again mame0.140u2 verified roms). Running the converter from the command line allows the user to see any errors encountered in the conversion (hence the reason I was able to change the necessary file name), unlike when the converter is double-clicked in which the command line window will close regardless of proper conversion.

  42. hame says:

    como cohto se instala este guegooooooooooooooooooooooooo??????

  43. wes says:

    i believe some of you are downloading neo geo cd roms and not regular neo geo games. there is a difference. some roms sites do not separate the files.

  44. Shooty-bloke man-type-thing says:

    I have an R4 and Strikers 1945 Plus works nicer than a nice thing, in nice town, on a nice day, when things are generally nice and not evil in any way, shape or form! 🙂 …. Then Skeletor walks in and crashes the disco, complete with a bottle cheap knock-off vodka and starts dancing like my nan on a bad acid-trip. *SHOOTY-BANGY THINGS FTW!!!!*

  45. Ian says:

    /\ Are you mental?

  46. Luiz says:

    affs consigo coonverter bios mais nao converte a romm ajudem me

  47. Captain Angry says:

    To everybody having trouble running NeoDS.

    1. Read the “READ ME” file that came with the emulator.

    2. Do what it says.

    If you can’t even manage that, you don’t deserve to play the thing!
