Ok this does work full screen with sound on the k800, however the only problem being that 0 is the fire button, you can move the ship with the joy stick but you have to use the o key to fire.

This is 240 x 320 version of the game (except for the language select screen which appears a bit smaller than the screen but everything else is full screen).

If anybody knows of a version of this which fires when the joystick is pressed instead of using 0 on a k800 then I would be grateful to know of it
