btw, the dev mode on the series x--that retroarch is official. every game aside from the mystical ninja prototype game has worked for all systems. the prototype isn't supposed to work with any emulators, but it works with original hardware. I tested it with the mc2sio on the actual ps2, and it worked without a problem. that was working designs last game. if you're too young to remember them, they were like the originators of the special editions of games, so all their games cost more, but you got a lot of shit with them.
