Quickly revisiting an old bug I already talked about here a while ago, but with more GIFs!

For literal years, there was a bug in my emulator that was just sneaky enough to kinda break a few games.

@kefen sneaky!

@Hiro @kefen nice post, thanks. BTW, do you have any unit testing in place for instructions or PPU behaviour?

@sardaukar @Hiro Thanks! I do not have unit testing — I barely have a workflow at all for this project — but I have been using test ROMs such as Blargg's (https://github.com/retrio/gb-test-roms/tree/master) or Gekkio's Mooneye test suite (https://github.com/Gekkio/mooneye-test-suite).

@kefen @Hiro Yeah, that's the approach I'm going for with my emulator project too. Just wondering if you had found a better way 😃
