PlayBoy Advance specifications

Added nearly 100 Opcodes.
Implemented THUMB Support
Many other CPU bugs fixed...MANY, about 30 or so...
Rewrote entire graphics core. Here's what's implemented:

• Mode 0 - Background 0, Background 1, Background 2, Background 3 with priorities, Vertical Mosaic, Horizontal Mosaic, Vertical Flipping, Horizontal Flipping, 256x256 through 512x512 tile map, Vertical Scrolling, Horizontal Scrolling.
• Mode 1 - Background 0, Background 1 with priorities, Vertical Flipping, Horizontal Flipping, 256x256 through 512x512 tile map, Vertical Scrolling, Horizontal Scrolling.
• Mode 2 - Background 2, Background 3 with priorities, 128x128 through 1024x1024 tile map, Vertical Scrolling, Horizontal Scrolling.
• Mode 3 - Fully implemented drawing routines, Vertical Mosaic, Horizontal Mosaic.
• Mode 4 - Fully implemented drawing routines, Vertical Mosaic, Horizontal Mosaic, Buffer 1 and 2 implemented.
• Mode 5 - Fully implemented drawing routines, Vertical Mosaic, Horizontal Mosaic, Buffer 1 and 2 implemented.
• OAM (Sprites) - Horizontal Flipping, Vertical Flipping, 8x8 through 64x64 size, Vertical Scrolling, Horizontal Scrolling, Implemented in Mode 0 and Mode 1.

DMA0 Implemented (Direct Memory Access High Priority)
DMA1 Implemented (Direct Memory Access Medium Priority)
DMA2 Implemented (Direct Memory Access Medium Priority)
DMA3 Fixed (Direct Memory Access Low Priority)
Keyboard support fixed...works now :)
Optimized immediate opcode data fetching.
Major general optimizing. Some demos jumped as much as 27fps to 60fps.
hblank removed for speed (not used in any games to my knowledge)
vblank minor optimizations and fixes, removes flicker from many demos.
Implemented a pretty powerful debugger featuring:

• Realtime instruction viewing during emulation
• Single Stepping
• Jump To PC
• Set Registers
• Set Flags
• Display GFX
• Debug Single Vertical/Horizontal Blanking
