i sorta have trouble recording the game in windowed mode. theres this movie saving thing in bizhawk, but idk how the hell to actually view the movie when i save it bc its in some sort of .bk2 format. so, is running the game in fullscreen mode (i use geforce experience to record) allowed?

noob question ik but just aking

Its fine to run in full screen. The bizhawk movies are meant for tas recordings, don't use those.
