The problem is its a black and white TV so i wanted the space invaders nes rom hacked to be like arcade.
cause then i could add an overlay and make it colour

i was playing psx on the tv to test out and u dont notice the black and white after a while.
Can't you use a colour wheel and have it spin real fast infront of a screen to get full colour? i know they did it for the gameboy cam to make it colour.
i saw some arcade emu's for the psx so i might try that if not it has to be a pong mini cab
