Changelog:
- Game Boy (Color): STAT OAM+HBlank IRQs only trigger during LY=0-143
with display enabled
- fixes backgrounds and text in Wacky Races
- Game Boy (Color): fixed underflow in window clamping
- fixes Wacky Races, Prehistorik Man, Alleyway, etc
- Game Boy (Color): LCD OAM DMA was running too slow
- fixes Shin Megami Tensei - Devichil - Kuro no Sho
- Game Boy Advance: removed built-in frame blending; display emulation
shaders will handle this going forward
- Game Boy Advance: added Game Boy Player emulation
- currently the screen is tinted red during rumble, no actual gamepad
rumble support yet
- this is going to be slow, as we have to hash the frame to detect the
GBP logo, it'll be optional later on
- Emulator::Interface::Palette can now output a raw palette (for Display
Emulation shaders only)
- color channels are not yet split up, it's just the raw packed value
