I have a gateway but I no longer have the blue cart, I want to play classic nds backups but I'm not confident on what I should do. I've done some searching but I'm not positive that I am not risking my gateway usage. Please correct me if anything I assume is wrong. If I get a r4i Gold 3ds with firmware V1.80b on it, I will be able to play classic DS backups on my O3ds with sysnand 4.5 Installing the firmware and the r4i gold 3ds will not affect my ability to use my gateway card. will I have to be in my EmuNand to use the r4i ?
