Thanks for the info. BTW, I don't remember a MAMEUI32/64 0.142 release so any idea about when the RAM issue was solved? 0.142 or 0.142.1?
I update the ROMset with Romcenter by extracting dat MAMEUI32/64 from .exe file. Would it be a problem to update from 0.141 to 0.142 or 0.142.1, because of the RAM problem? I just don't want to spoil the whole ROMset...
