Here is some completed images of the DMG, the buttons are from a NES controller (the A,B, and D-pad buttons all fit right in with no mods)
Ever wanted to do something to your DMG besides paint it? Me too, so I busted out my sculpting tools today and some Aves Apoxie Sculpt and went to town. My original idea was to just do some red Mario style bricks, but in tradition of the DMG's nickname "Grey Brick" I decided to do just that.
Step 1: Prepping
I got this old DMG-01 from the goodwill for 4 bucks, so I wasn't going to be bummed if I screwed up somehow. Take your GB apart (assuming you know how and already own a tri-wing screwdriver) all the way down to just the face plate. Then carefully pop off the screen (good time to replaced your screen cover if need be). After you have it all stripped give it a light sanding (I had to go nuts since my $4 DMG was crapily spray painted black)
