Mamewah Trouble with adding new emulator

[Arcade Rabbit]

I'm using Mamewah and it works like a charm with MAME, but I wanted to add an Nintendo DS emulator aswell. And I'm using the NO$GBA emulator. So I set up a new folder in the config folder named "gameboy" since it can emulate any of the nintendo handheld consoles. But I can't get any roms to show up in the list. What have I done wrong?

This is my gameboy.ini

### gameboy.ini (mamewah v1.69) ###

That looks fine to me. Did you generate your list in Mamewah?

Access the options menu (2)
Select Platform (1)
Pick Handheld Nintendo (1)
Access options menu (2)
Go to Games List Options (1)
Generate List (1)

If you are using Groups, make sure you added that to your groups .ini file

Yes, I did generate the list but it's still empty.  I'm not using groups, hm. Should I try grouping?

[liquid8]

Groups are just helpful if you have a lot of systems and want to separate them - like Arcade, Consolde, Handheld..

If your list isn't generating, are you sure your roms are not in zip format (or 7z for that matter?) instead of nds files?

As long as you have the correct rom path, correct file extension and are using rom_folder to generate - it should pick up any files in that path.

Double check - when you copied the mame config folder, do you have the list ini files in there? those are the mame-0.ini, ... - rename mame-0.ini to whatever you named the system config folder, like gameboy-0.ini - that is the configuration for the main list. Also look in the mamewah\files folder and see if the list file is generated there - it would be something like gameboy-0.lst

If all else fails, see what the mamewah.log file says after you have tried to generate the list..
