Color effects can now be disabled in WININ/WINOUT registers
Alpha blending can now be applied multiple times (Lord of the Rings)
Disabled alpha blending for pixels with no second argument (Lord of the Rings)
Added window support to bitmapped screen modes
Changed LDM instructions not to write back base register if it has just been loaded from memory (Golden Sun 2, Kong, VRally 3, etc.)
Now setting R12=0x04000000 in VBlankIntrWait() and IntrWait() (Bubble Bobble old and new)
Added QOpARM() and WOpARM() functions for fast opcode fetching
Removed data rotation in unaligned 32bit writes (Downforce)
Modified BIOS decoders that write to VRAM to use words, not byte
Now returning correct 'broken' values when program tries to read BIOS area by bytes and 16bit words
Now doubling byte writes to VRAM and palette
