I’m wondering if and what psx/ps2 dual stick controllers are able to use the right stick to map the buttons to play games that would traditionally use two sticks but were released before the original analogue controller was released. I just picked up Namco Museum vol. 4 because it includes one of my favorite old arcade games: a tank game called ASSAULT but it is virtually unplayable using the d-pad and buttons. Other games with similar control would be Project Overkill and those using Smash TV-style setups. I remember I used to have an old mad catz ps1 dual shock that had a mode to let you use both sticks like this - are there any equivalents for ps2? Would any of the flight stick-type controllers brought out for games like Ace Combat work?
Ideally I would find/build something that resembled the really cool Virtual On dual stick controller for the Sega Saturn
