I tried to add an LED to my original screen, and it didn't go well. I ruined it, to be frank. The next step had to be something more straightforward, and this was that solution.
The precut bracket fit right into place and the screen sits neatly into it with a border around the edge to help it fill the aperture, since the screen isn't quite as big as the original. Soldering the single wire was no issue, and the touch pad sits at the top of the handheld, neatly out of the way. The product page didn't seem to mention the multiple palettes you can access by holding the touch sensor instead of just tapping it like you're changing the brightness, but there are 5 different settings: grayscale, green, red, yellow, and a faded one that looks more like the original screen but has less contrast than the others.
This was a great upgrade for the Game Boy Pocket I got back in the late 90s along with the new case I installed, the whole thing feels like it's grown up with me now.
