SpawnWave released today video mentioning this mod and that part is full of shit
It's not "Secret Menu". I didn't find those settings in romfs ready to use. I took files responsible for settings, compared them with PC files, copy-paste from PC to Switch files with some tweaks and testing. Switch Pro is not coming.
Max FPS option is not for unlocking FPS, but rather for locking to 30 FPS for people that already has 60 FPS mod from other topic. I'm still testing some things, because just locking to 30 would be pointless if that means staying with the same dynamic resolution frametime interval. My goal is to find a way to save this lock with custom frametimes.
That's it.
