Yep, I wanted to do a playthrough of Sonic Adventure DX. I played it back in the day on the Dreamcast, and liked it just fine. Unfortunately, the options for adjusting the controls for the game are somewhat limited. It won't let me used the D-Pad for movement bindings, and the joystick is broken moving directly forward, and only directly forward.
Can't play this particular game this way. This project will have to wait.
