however many moons ago, i installed reinand CFW onto my N3DSXL. well fast-forward to today, my N3DS is on the latest firmware for reinand and upon trying to play a DS cartridge of Professor Layton, my 3DS just hangs at the black screen. on the other hand, 3DS cartridges still seem to be working. i never experienced this problem before installing the latest firmware and i wanted to know if there was a quick fix for this that i could do? after learning the process of installing .CIA's, i never looked into anything hacking-related anymore since i figured i wouldn't need to do anything so long as my games work. basically, i am pretty much completely unfamiliar with the process of hacking so simple explanations would be much appreciated! thanks in advance y'all!
