I've been using MacMAME on a dual core iMac for a while (MacOS 10.5.8) which worked fine, but recently upgraded to 10.6 (Snow Leopard) and noticed that MacMAME all of a sudden came to a halt (the games themselves play fine, but everything I do in the main window is very delayed with the beachball coming up all the time as well). As I was told to install Rosetta from the Snow Leopard DVD I assume MacMAME is somehow emulated (though I find that strange as it worked find in 10.5 on the same machine). My MacMAME version is 0.77u2a which I know isn't the latest, but I believe it's the latest one which doesn't force you to keep the ROMs etc. inside the "Documents" folder but instead keeps it inside the MacMAME folder within "Applications" which is what I prefer. I haven't been keeping up with developments but understand that MacMAME is now unsupported/undeveloped and that there are other emulators which have taken its place. I've tried several of them but they're confusing to set up, don't work with my ROMs or don't work at all. I was quite happy with my current version if it wasn't for the slowdown in Snow Leopard. Suggestions?
