I just set up and briefly tried out my new Gateway. Impressed with it so far. Just a couple of questions: - My 3DS XL is on Firmware 4.3.0U. I'd like to play my retail copy of Fire Emblem: Awakening on it, but that requires Firmware 4.4.0U, and I've already installed the Gateway exploit. Could I use my retail copy of Shin Megami Tensei IV to update the Firmware to 4.5.0U? - Will eShop / pre-installed 3DS games and apps work in Gateway mode? - When I want to change the game on my micro sd card, do I just reformat the card? - Can I remove the exploit from my 3DS completely if I want, and leave no trace of it being there? Thanks for any answers. EDIT: Technically that's more than a couple of questions... Oops.
