just switches between PS1 Digital and PS1/PS2 Analog mode
it was a weird thing back then because analog sticks didn't exist until the Playstation Analog Controller (with weirdly elongated handles and concave thumbsticks) showed up in the latter half of the PS1's lifespan
a lot of games only worked off of the 'Digital' (aka DPAD, shoulder buttons and face buttons), while a limited selection of games supported the Analog mode (all of Digital + 2 analog sticks and their respective buttons)
a lot of early PS2 games also straight up still had the same design, example being Armored Core 3 and Silent Line
