>>30979208NTR is for 3ds games
The way the rom is loaded in is as a virtual console game, so literally all I could try to do is figure out how to extract my save (which would be a bit fucky), throw it on my pc, load up the game through an emulator, cheat for items, export save, and import it back onto my 3ds
Might do it later on if things get on my nerves too much
