wdc65816: fix PLB wrapping in emulation mode #299

Closed Screwtapello closed 6 months ago

Screwtapello commented 11 months ago

@asiekierka found an issue in ares' WDC65816 emulation and we can probably (hopefully) copy the fix from ares.

Regarding PLB, it looks like it reads from $200 and snes9x, mesen, bsnes, and the official CPU manual all got it wrong.

Reproduced and verified on real hardware via https://github.com/gilyon/snes-tests
