I've been trying to hack Pokemon Sun/Moon today and found an unexpected problem - decrypting a ROM of the game (.3ds file) is now impossible because the file is too big. I can move a file less than 4 GB on my SD card, but it doesn't let me to do the same with the >4 GB .3ds file of the game (why did it have to be so large?). The error I keep getting is "File is too Large for Destination File system". I tried to look up some solutions, and they either failed to work (I was interested in the ones that don't wipe out the whole SD card because I obviously have my CFW on there and re-installing everything is huge headache) or just advertised some malware by baiting with the search. Can I decrypt the game in any other way? Sadly, I do not possess a cartridge.
