The version of the roms need to match the version of mame32
Find out what version roms you have, and make sure the mame32
you have is the same version. If not, get the proper version.
If the versions match, make sure you don’t unzip the roms.
Place the still zipped roms in the “roms” folder in mame32.
After starting up mame32, you need to do an “Audit” so that mame
can check the roms to insure they are intact, and the correct version.
(chose “file/audit all games”)
If the roms are good, and the correct matching version, the games
icons should turn green in the list. If they are red, the roms are
bad, or the wrong version.
Hope that helps.

A google search of “mame32” should help you if you’re still stuck.[/I]
