I have one thing to say about alt+tab = splice. Doing a splice like that would result in some audio artifacts and mouse jumps (granted that they don't put their mouse in another location). And, excusing that, assuming their on an emulator, their taskbar will highlight the last program touched, whether it's live split or OBS. There is no reason for the run being removed. As for the run being possibly cheated, It's 20~ hours long. Who is dedicated enough to splice that run while dealing with AI.
