I think the problem is the patcher, if I set the Note FPS target to 120 & check the "Force Note FPS Target" box, it won't boot. When I leave the Note FPS at 60 & uncheck the force box, it works, but the charts only play at 60 FPS while the rest of the game is 120.
I'm also having issues with the subscreen, but I just disabled it via the patcher for now
