Also are non legit copies of the game allowed like stolen ones (No I did not steal one) My friend has one and they were wondering if that was allowed aswell as they want to get into the speedrunning

The only mouse I have is the logitech g502 se and i was wondering if runs could still be valid if there is no scroll wheel active like using 3rd party software for remapping it? I dont use scroll wheel anyway for it anyway.
