True, but on the other hand, gambatte doesn't seem to support things like savestates at the moment (going by gambatte-qt and the source) , I personally am probably not skilled enough to add them. Compatibility wise I believe it is quite good. Again I'm probably not good enough to optimize gambatte but if you are that sounds reasonable. Perhaps I'll just add a few more features to GnuboySDL to tide everyone over until you get something out
