Hate to burst everybody's bubble, but this app is crap so far and plays only a few roms...if this app is a work in progress at this point and only works for a few roms then this dev is being a complete d-bag by charging everybody $6, especially if we're all expected to do his job for him by giving feedback. He should have spent a few more weeks in development, but he got greedy knowing that other devs are possibly about to release a better version. HOWEVER, if yongzh gets his stuff together and gets most of the roms working WELL and in a TIMELY manner, then I will most likely support his further work. Yet if he lets this thing drag on and someone else releases a much better emulator (ex. FPse), then I will add him to the same list as that other dev...cough cough...
