Yes that's what I'm going to do.
I still have some insulation tape that I bought to put under the hood of my Celica GT4.
Whiche screen driver are you using ?
I use HighGFX but it's only 4 colours in 1024x768...
Have you tried to use blackborders or blankborders (something like that) to help your screen to remove those big borders?
(because it looks like an Atari ST lol)
