Hello, I have an old DSi LL with Zelda Four Swords and I'm pretty sure I have Xidia (spelling?) too. But they are on my DSi LL not my 3DS LL (both Japanese). My 3DS LL is currently on 11.0. If I update my 3DS LL to latest firmware and do a system transfer to get these exploit games onto my 3DS LL, will DSiWarehax work? Will that then allow me to downgrade? Or has something been patched? Should I bother? Or is it a lost cause? Thanks!
