Jet Grind Radio seems to play alright. I can’t really play it with how my joystick is atm, but it does “play”, and the frame rates seem workable so far.
>.> the itty bitty buttons on the back of my gameboy that act as L/R triggers are hard on the fingers for games like shenmue and jetgrind radio, that require you to hold them down for extended periods. But that’s an issue on my end i will eventually remedy.
