Hi Fabricio. A couple of questions since I'm currently unable to download it and check:
a) Does your version of the dat contain only fighting games? Or non-fighting game (like Pac-Man, etc.) as well? b1) Is your version long-hand only? Or is there a short-hand version as well? b2) Does the MEWUI interface support the short-hand versions with the shorthand glyphs that we created for MAMEPlus?
To the community: What's your preference on these issues? I look at what they do with the Japanese command.dat (that's actually incredible...) They do long-hand only, with even more non-fighting games than the English one supports.
