GBC-101 modded motherboard and solderless ribbon cable
You'll be purchasing a modded GBC motherboard (pin3 mod, all pins cut flush and masked, contacts cleaned, led removed) and a modified ribbon cable which requires no soldering to install.
What you need:
GBA101 LCD - Chinese reproduction, not used parts
Modified GBC shell, you can mod your own or buy pre-modded. It's a pretty big job to remove enough plastic and keep it looking neat, but many have done it. Look at Kylesawesomelife YouTube video for guidance (he's releasing a new video in the coming days!!) Avoid ThisDoesNotCompute's guide as he made a real mess of the mod.
Vinyl or electrical tape to mask a black border. I recommend automotive pinstripe tape as it has a sharp edge, easy to handle and doesn't shrink or make a mess like electrical tape. You can skip this step if you don't mind the white border
Motherboard versions will be shipped from available stock v02-v06.
Untested with Everdrives - I've heard they work but some have had issues with the earlier versions and the eBay clones.
If you're unsure, ask questions!!!
