I have a 3DS system that I previously used with R4i Deluxe. How do I delete/uninstall that I installed from R4i Deluxe before I switch to Gateway? Do I just format SD Card inserted to 3Ds and install Gateway or is there any other thing I need to do? I am kind of worried that Gateway will confuse the cart as using a clone cart and brick it just because this system was previously used for R4i and have some stuffs left from the previous cart. Thank you!
