Thank you! I replaced the luma/title folder and the remaps from that 7z and it worked.
I am still having a weird issue with Kid Icarus Uprising. The remap works, and in the menu I can use the c-stick as the face buttons, and it also works when having a land battle in the game, with the c-stick moving the reticle when the control options are set for the face buttons to move the reticle. However, in air battles the c-stick does not move the reticle, it instead moves Pit, as if it is just replicating the circle pad. The actual face buttons still move the reticle, but the c-stick is just replicating the circle pad.
I'd like to know if anyone else has this same issue or if it's just something weird on my end. I know KI:U is one of the first games that came to mind with rehid so I'm curious if this is a wider issue.
Thanks for all the help! Looking forward to playing around with more games.
