Video: Added 4:3 aspect ratio support in full screen mode. You can change of common 3 resolution you want to be displayed. This is more likely playing in a real TV.
App video crash: I tested the emu in some basic GPUs like Intel ones. It was sometimes crashing in this GPUs. I discovered that changing some compiler settings was the error.
APU: Fixed Triangle Channel problem that some games didn't sound fine.
SOUND: Added a "low pass filter" in sound generation. It sounds "better" not "too much better", but as i said a "little better".
SOUND: Setting volume too high sometimes, in some games caused the sound to cut off.
Improved some code.
