Question about alternate romsets.

[icez]

Hey, I've been repairing and working with real arcade hardware (mvs / neogeo mostly).

I realized that some some roms would not work properly on the real hardware when burnt onto eproms (only the samples V roms)

Have some Neogeo roms been pre-patched after being dumped ?

Im also having trouble dumping some roms, especially 32mbit roms that my programmer is reading wrongly, one line out of too is blank in the buffer (when read as a 27c322 or any other 32mbit device).

Is there any trick there ? the pinout of the toshiba mask roms used is the same as the 27c322)

I hoep someone know about this, I'm sure it could help quite a few people.

Your best bet would be to post a request over in the rom dumping forum over at www.mameworld.info its where most of the guys actually dumping the roms live. There have been changes to a lot of the NeoGeo dumps fairly recently.
