A few things noticed on "Super Mario Allstars", this stubs SetGpuTimeSliceBoost and adds a fix for the "Return to title selection" menü.
Basically ExitProcessAndReturn now starts/restarts the process on program_index 0 (main menu / title screen) and fixes a device memory clear when using that method.
