Good app, great value.
PS A quick addition to my previous post. 'Indiana Jones' runs just fine =) Sadly, even with the update I cannot get Turtles or 'Golden Axe' to play and as a Mac user cannot use the suggested method to change romsets for compatibility. Still, this emulator shows great potential!
Finally, a MAME app for Android that actually runs =)
At present I can only get a handful of my hundreds of roms to actually play... but the ones that do open up run with very little slowdown and, unlike Tiger, play full sound! Score!
The interface is very easy to use and I'm very happy with the progress this app is making. I'd love to see support for more of my favorite oldies such as 'Teenage Mutant Ninja Turtles' and 'Indiana Jones and the Temple of Doom', but perhaps this latest release addresses that (I have yet to try the March 2, 2012 update).
