Cool, I'm going to have to figure out how to build total replay on linux so I can try the latest.

One weird thing, I was trying Gumball (having watched a video on youtube) and when playing with a joystick I can speed up production with joystick up but can't slow down production with joystick down.

If I hit CTRL+K I can do up/down with (E and C) left/right (S and F) D to center, Return to toggle crosshair, Space to flip valves.
CTRL+J for joystick.

Running applewin under linux with wine, the joystick can do up/down, but under mame only up seems to work with gumball.
