Some checks failed
CI / build (push) Has been cancelled
* All programs (rgbasm, rgblink, rgbfix, rgbgfx) support `-W` warnings * Use `rgbgfx -c dmg` for grayscale 1bpp/2bpp * Use new string functions and operators * Use `?` to silence nodes in warning/error location backtraces * Use single-quoted character literals for numeric values * Do not warn about overwriting bytes in the corrected header
