Recently one of my ds game's cartridges is acting up and keeps on freezing or not loading properly and I'm getting fed up with it. When I look at the golden pins I see that there are some green marks and I tried to clean it but it simply won't clean, so I want to know if I can open the cartridge and take the "game" out, then open a separate cartridge and switch it? Would I have to reconnect wires or anything like that? Is this possible to do, or is it likely that I'll just ruin my game by trying this?
