Roms for MAME are very temperamental. You have to use the version of MAME that the roms are dumped for. E.G. If you download a 0.37b5 rom you have to run it with the 0.37b5 emulator version of MAME. The MAME32 with 489 games is from the year 1998. They're old and won't run except with the emulator that comes with them. So again, if you get 1.440 roms, you have to run them on a 1.440 emulator version of MAME. Hope this helps.
