I use an elgato game capture HD which is discontinued but very easy to pick up online for pretty cheap (might wanna spring for the rca cable for PS1 stuff if yr interested and can find one) passing through an hdmi splitter to allow it to capture PS2 footage. I connect my laptop to 2 TV's (one for pc/rlly just obs and the other for Ape 2)
Admittedly, not the sharpest fidelity (I think it outputs at 480/720p(?) but still good and once again, pretty accessible if you aren't too concerned with having the highest end gear.
Hope this helps n you have fun goofing around in this goofy game! If you need any help, hit up the Discord sometime.
Casino City (aircrawls, first sick stage) Simian Citadel (the big tech, starjumps, stage is blue n coool) Skyscraper City (outside of window monkey, solid n some of the coolest rooms n catches in the game)
2nd half of ETM, Lookout Valley and Blue Baboon are all pretty chill too
