I like those ideas. About the key combination however I’d recommend another combination, mostly one that doesn’t involve keys with an actual function, just in case (afaik the buttons without function are X,Y and SELECT, tell me if I’m wrong). I thought of Y+SELECT (or backwards), avoiding X as X+Y brings up NTR in the cia version which in case you don’t know is a tool you can use to do in-game stuff like cheating, taking screenshots and also recording on new3DS only. Wouldn’t affect the player as it stops everything to display a menu in the bottom screen (would be sort of like pressing HOME I believe), but just in case…
