I can't get my MAME to work. PLEASE HELP!!!

[Snake Eyes-Joe Ninja]

I downloaded MAMEUI32 0.129, and I downloaded ROMS that list a certain group of files, but when I go to play the game, it tells me it can't find those files, ERROR, etc.

Can anyone help with this?

Well, what game is it? It's possible that you have a clone of said game and need the parent ROM set, or in some cases such as NeoGeo you might need a zip of the BIOS ROMs as well.

Also, sometimes a ROM set will change. An old version may be expecting certain files while a newer version may expect something else. See if you can verify it using something like ROM Center (though you may wish to update to the most current version that you can get here.
