My name is Max, I've known about the GBZ for a while now. Saw it for the first time on Reddit, and waited for the whole GBZ series to finish so we could start building.
Two of my friends and me are going to start this project together (3 GBZ in total). We already ordered the Raspberry Pi Zero's, the Game Boy shells (No original Game Boys) and we will order some custom hardware made by the fine members of this awesome forum!
We are very excited to begin this quest of soldering, cutting and all that stuff.

If you have any questions, don't be afraid to ask because I'm pretty sure we'll ask you all some questions soon lol.
