No.21461 ICEknight Tester May 26, 2023, 22:36	But if graphics bugs are not reported so that they can be fixed, those systems will be marked as "imperfect graphics" forever.

Game Boy Color is one of those systems. The PPU needs a complete rewrite anyway, and at that point everything will need to be retested and existing bug reports will be useless.
