so I have two files on my 3ds- both related to smash bros. CTR-P-AXCE, and CTR-M-AXCE. the CTR-M is what I'm worried about though. I know the CTR-P is my game, but what's the CTR-M? can I safely delete it from my sd card? will it affect anything in particular? I've had smash installed before now, could it be left over data? my card is only 8 GB, so space is an issue from time to time. Thanks in advance!
