So I've been meaning to do a little wireless interaction with some of my games. I have everything set to go but I'm missing on important thing. The newest shop update, and a psycho ex girlfriend stealing my DS Lite has prevented me from updating my firmware. However, I think I found a way around it but I wanted to check here first. So here's my question: If I format the system memory on my DSi will I be able to start using my Flash Cart again as I won't have the current system update, preventing me from using it now?
People have been saying it is not possible to undo an update on a DSi, but I don't own a DSi so I'm not sure.
