We haven't got that far yet. I do hope he can dump at least the program rom though.
I'm a bit confused by the way MAME boots this game at the moment. By default you get a hardware error 8B which I don't think is related to the timekeeper and if you modify the timekeeper rom THEN you get the expected 11B error. Either way though it doesn't know what the game or region is.
SS2 will work on SS1 hardware and that boots so not sure what the problem is with MAME.
I am starting to see a trend though with these NVRAM files, the first few bytes are the game ID, then the year (this has to match too btw) then the region, then what seems to be a security code. Only the first byte of this seems to change depending on the region, 9 for US, A for Europe and therefore I assume 8 for Japan? We will see I guess.
