I'm not arguing that. All I'm saying is that I prepared the ground for insertion (as their colouring before wasn't ready), and you inserted it into your ROM and changed the pallette. So, credits for that would be slightly nice. Just until you replace them.
And it wouldn't be the same if you took a few tiles, as that is kinda the point of ROM Bases. A starting point to add your own stuff. You used some tiles from my ROM Base, exactly what I wanted people to do.
