This one time, I was messing around in 2-player mode (by myself) in SF2 to practice some moves. I notice that Player2 seems to be active, and I figured that, in the absence of a 2nd player, the game must have automatically filled the space. So I’m like “oh ok, guess I’ll train like normal”. Player2 managed to KO me, mostly from using fierce kicks to knock me out of the air (Player2 was Dhalsim)
But then I figured out what happened: apparently, the controls for player1 and player2 overlapped somewhat, but the mappings were different. For example: the same key I used to crouch caused them to perform a jab, the left/right directionals seems to be inverse eachother, and I’m pretty sure the jump key for player1 was also bound to fierce kick for player2. So basically, I managed to kick my own ass with random inputs.
