i also used snes buttons and one of play it loud screens that were in better shape as the one it already had.
i also fixed the problem that the backlight would light up the white case outside of the screen (used black tape und black glue).
after reassembling the case for about 20 times - yes that awkward moment when you assembled everything and notice that there is a hair or dust behind the screen >:O
i used the diffusion film from kitsch-bent on the white dmg but it didn't make any noteworthy difference.
the black dmg got silicone buttons and a new black screen.

|what a couple|
|really love the colour combo|
