Brilliant! I award the "mad scientist" award!

We need Galiga... just to put it on the bridge of a flying Aircraft Carrier

Alright then thanks !

Yes @Moss, the GameInput framework used on this game detects every key that can be detected by Programable-blocks, Just replace the lines

if(input.A) Position += new Vector2(-InvaderGame.player_speed, 0);
if(input.D) Position += new Vector2(InvaderGame.player_speed, 0);

to

if(input.Q) Position += new Vector2(-InvaderGame.player_speed, 0);
if(input.E) Position += new Vector2(InvaderGame.player_speed, 0);

(use Windows Notepad or something like that to find this lines)

This is amazing any plans to put other great Atari games into a cabinet

This is great but is it possible to change A to Q ?

Amazing.
