No.03079 Tafoid Administrator Nov 22, 2008, 23:31	Are you using any cheats? This could effect emulation fitness - and possibly cause crashes. There is an MCU according to the source file which mentioned it need proper implementation for that game which might also be involved in protection. If you or someone else could produce a save state or .INP shortly before a crash - that would go a long way to validating this as a bug and looking for an answer.
