Changelog:
- nall: `#undef OUT` on Windows platform
- GBA: add missing CPU prefetch state to serialization (this was
breaking serialization in games using ROM prefetch)
- GBA: reset all PPU data in the power() function (some things were
missing before, causing issues on reset)
- GBA: restored horizontal mosaic emulation to the new pixel-based
renderer
- GBA: fixed tilemap background horizontal flipping (Legend of Spyro -
warning screen)
- GBA: fixed d8 bits of scroll registers (ATV - Thunder Ridge Racers -
menu screen)
- SFC: DRAM refresh ticks the ALU MUL/DIV registers five steps forward
[reported by kevtris]
- SFC: merged dmaCounter and autoJoypadCounter into new shared
clockCounter
- left stub for old dmaCounter so that I can do some traces to
ensure the new code's 100% identical
GBA save states would have been broken since whenever I emulated ROM
prefetch. I guess not many people are using the GBA core ...
