I call my project the Game Boy Color Advance, since it is a Game Boy Color that is shaped like a Game Boy Advance. I will take a Game Boy Color and "Horozontalize" it, hopefully adding fun extra features that were not in the original system, like a front light screen, and rechargeable batteries.
Some random extra features might come about as well, keep an eye out for those.
This mod is taking priority right now as it is for a time limited contest.
Here is a mock up of the system, I drew this in MSPaint.
