Neo Geo Roms Not Working

Problem when using 'home' system spotted: be sure to have the bios file 'aes-bios.bin' in your neogeo.zip file (still not working very great) - Added z80 and 68k overlock in preferences (improve neogeo framerate on games like metal slug) - Fix child roms not working (metal slug 4 plus, Puzzle De Pon! Hi guys, hope you're well. Can anyone help me, I simply cannot get any Mame or NeoGeo roms to work. I've followed all the instructions included in the recalbox roms folder text file, I'm trying to run 0.78 mame roms which I'm told are the most compatible, I've tried using the NeoGeo roms. Ill start by saying I have read and searched the forum on how to fix this but nothing worked. I have a whole folder full of Neo Geo roms. The are all,zip files. Is that my problem? Ive tried running it through retroarch and nothing would open, then I tried running them through a mame rom and not. I've had a hell of a time getting GnGEO to work as well. I tried every conceivable place to put the BIOS (both zipped and unzipped) to no avail. I'm certain that a number of roms I tried to load are from the correct, compatible romset so it is most likely an issue with the BIOS. Tried many different versions of the Neo Geo BIOS as well but no luck!

Neo Geo Roms Not Working

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.

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:

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:

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).

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.
