Goku Hishouden & Goku Gekitouden in hhugboy (and VBA, all versions) image image BGB: image image These seem to be the only games affected by this issue so guessing some quirk in the way they send SGB data. May occur in other games by the same developers but I have literally no idea who developed them (TOSE?)

the problem seems to be when it sends an ATTR_TRN packet at the title screen (and in other places attributes are used), the data read from gameboy VRAM into the SGB memory isn't what it should be..

I've attempted some debugging but idk much about the SGB at all and the emulators it works properly in are all closed source so I don't have much to work on
