SvC Chaos - SNK Vs. Capcom Chaos, a NeoGeo MVS dump.
If the romset is correct and up to date, should work on MAME, butsvc.zip was also the common name before was emulated on MAME, so might be and older dump not directly compatible with any emulator: perhaps a hacked emulator it's needed or a customized one (Nebula), but not recommended, we can't point you any emulator hacks here
Anyway feel free to post the ROM names (inside the zip) and CRCs if possible
