Great. :) You who do this are awesome. :) many people don’t want to create cheats just because of online cheating. :/ but i only use thing offline. To mod characters to be strong like in Wiiu did help very much. :)
We have CrossArc to view the files of the game. To load mods, view my guide. But injecting into the data.arc and having a copy of that on your card is the only method of loading mods as of now. Soon it will be a drag and drop system like most games and/or Smash 3DS and Brawl.
