Now that I'm older though, a wormlight doesn't really cut it. This tutorial will show you how to very simply add an internal frontlight to your Gameboy Color. A feature that blows your wormlight out of the water.
Step 1: What you'll need.
2. A Broken Gameboy Advance Sp. (Make sure the model is NOT an AGS-101, this version uses the wrong light)
3. Tri-Wing screwdriver
4. Soldering iron and basic soldering skills.
5. Some wire and solder.
Step 2: Disassemble and remove screen
Once the screen is unplugged, you can remove the motherboard, leaving you with the screen inside the front casing. The screen has some adhesive around the edges, so it might take a little pulling to get it out, but it shouldn't be to difficult.
