# Loading B/W games with GBC hardware set results in severe gfx glitches

- Source URL: https://github.com/MiSTer-devel/Gameboy_MiSTer/issues/45

So, when you load up a standard non-colour game in a real GBC, you get the standard boot intro and then the game loads with a predetermined palette if the game ID is found in the list in the bootstrap rom (https://tcrf.net/Notes:Game_Boy_Color_Bootstrap_ROM). Palettes can be set with a button press when the Game Boy logo loads. Benefit of using GB games on a GBC include that there's actually more colours in play - sprites have a separate colour.

Anyway, it's pretty glitchy on the current core build. I've taken some comparison photos to explain. MiSTer screenshot first, real hardware second:
