Hi Tyrem,
as you know - I have the same TV Ideal Arkanoid.
Would be best to team up here

There are different Arkanoid version. Which one do you wanted to use?
I was thinking in going with the yellow/purple Control Panel (and maybe using this image as the marquee). In addition I have a friend over in Bremen who owns an original TV ideal Marquee for the game (which is entirely in purple if I remember correctly).
The TV Ideal is wooden on the sides.
I was thinking of leave it as is....or give it a grey coat and maybe add some romstar images? I like the artwork from my amiga game boxes so maybe this would be an option for a nice side art, too.
