So I want to mod Breath of the Wild, and Smash 4. SDCaffiine is nice but Breath of the Wild pushes mods out of RAM after a while and it can be unstable with Smash 4. A workaround for that would be editing the files with FTPiiU Everywhere, thus permanently installing the mods. But this too has drawbacks because I still want to play vanilla BotW and Smash 4. So my question is if there is a way to change the Title ID or some other identifier in order to install both a vanilla copy and a modded copy of games, without just having two hard drives and swapping them.
