yes but some problems with the audit feature. before with osx10.4 it got some of the "good" roms, but not all. So not an entirely perfect feature to begin with, but a nice one. Now it's not working. So I'm using the favorites feature. which is just as good, but a pain in the ass. The OpenGL runs much better with osx than mac mame. Running Soul Edge and Kinst2 is actually possible and not skippy. Virtua fighter looks nice as well. Some over all copyness in the emulation, but time will fix those things. My question is, whens the next update of os x? I think it has the most promise. PLEASE KEEP WORKING ON IT! lol. How much do I have to pay, to get a better audit, a prog that doesn't quit all the time, quit when the rom doesn't load, etc etc... ???? $$$ ????
