That's not good! That means R-Type Leo is out of the question on your machine then? Get a new machine man. My soundcard might be shit but it does on virtually every game on MAME at 100%! Why that is I don't know, when Raine runs like shit, the latest version of mame runs like the dogs wotsits!
I don't know what version of mame any of you guys are using but its compatible with a hideous number of games now! Street Fighter Zero 3 and Street Fighter vs X-Men are now working and at 100%! I still say mame is the dogs dangly bits when it comes to emulators! Accept no other!
