>>34834740>3DS has an IR port>Game Freak didn't bother emulating GBC's portBusiness as usual I guess.
Anyway, I don't know about save editors but it should be possible to turn a 3DS save data into a regular .sav (and viceversa) which you could then use in an emulator to use gameshark codes that I'm 100% confident exist
I would know since I used them back in 2002Or maybe gameshark codes could be turned into NTR codes? I haven't looked into that.
