-corrected several CPU instruction timing details
-properly implemented OAM DMA with all its timings etc
-corrected some memory bugs and improved timer accuracy
-added basic serial I/O control support as some games rely on its interrupt

GBC BIOS support and support for older colorization hacks, see README for details

more GBS compatibility

-dont close emu when opening with unsupported file or no file at all, display error message instead
-dont close emu on invalid cpu instruction, freeze game instead until a button is pressed
-set window title more proper
-display currently playing .gbs track on screen rather than just on the console via bitmap font

use short audio output by default now, it is good enough and gives a good performance boost together with the compiler changes

-keep audio float output as default and allow short output via a compiler option instead
-added short clipping to prevent ugly clicks in the audio
