GoBoy v0.5 introduces a number of changes that improve the accuracy and performance of the emulator. A new APU emulation implementation now correctly times the audio with the cpu emulation, resulting in much more accurate audio playback. There have also been a number of improvements to the GPU emulation, fixing multiple sprite ordering issues and rendering bugs. Finally there are also a number of changes to improve the emulator performance.
