Hi! I've been wanting to change the shell for my EZFlash 3-in-1 Expansion Pack because it's white and I have a black DS. I've been suggested to swap it off with a shell from a useless GBA game cartridge. Would this work? Is there a step by step procedure to do it? Sorry if this sounds like a very stupid question, but I currently own no GBA games (skipped out on the GBA generation) so I don't know how the cartridges are held together and built.
