... I just wanted some smokes, man! (crashes car into tree) No, I mean is it safe to delete CIA files from my 3DS? I installed a Game Boy Advance game that was improperly patched and didn't run, and it's cluttering up my home menu. Can I safely remove it? I tried using FBI to delete it but it didn't do the job. Also, aren't CIA files supposed to run faster than 3dsx files? Because I haven't noticed much of an improvement with RetroArch in particular. I realize an Old 3DS isn't gonna run them very well, but I have to believe it can do NES emulation better than this.
