byuu says: Added MBC1 emulation, although battery RAM doesn't save or load to disk yet. Made up a fake MBC0 which is really just saying 'no MBC', for consistent handling of all MBCs. Added bumpers to stop ROM/RAM out of bounds accesses. Added STAT interrupts for LY coincidence, Vblank and Hblank (not for OAM access yet, I don't know the timings.) Fixed timer interrupt [Jonas Quinn] Made all interrupts call a CPU function instead of just setting a flag for better control (to allow below addition.) Added HALT and STOP emulation, the latter permanently locks the Game Boy for now. The former breaks on interrupts. Rewrote all the rendering code to suck 50% less, though it's still absolutely miserable and scanline-based. Added pixel-level horizontal scrolling to BGs. Fixed OBJ rendering error that was making them render upside down (I was flipping to compensate before.) Added OBJ 8x16 mode. Added OBJ priority support. Added window (but it's broken to all hell on Mega Man II.)
