Hello everyone I have Boycott Advance installed on my 2012 Macbook Air and the emulation is nearly perfect. Save states work. It works with a PS1 USB controller just fine. However, the sound is really terrible, it sounds weak and like static. Fullscreen works though! I also have Visual Boy Advance 1.7.4 installed. Fullscreen does not work, it crashes every single time. The largest window size is 4x set in preferences which isn't big enough for me. But the sound is 100% perfect. Is there an emulator that allows fullscreen and perfect sound under OSX Lion?
