Worklog Egg Boy Color

[leggomyfroggo]

Hey all! I'm back for a second year, and intend to finish this time -- as a matter of fact, I've already made it farther than last year by posting a thread.

Setting the Stage
You may know me from my prior projects where I made custom form factor Game Boy Colors using original hardware:

1. Frog Boy Color: full size, mostly fully featured, wide Game Boy Color -- serious business
2. Tad Boy Color: small, while still using OG cartridges, most features preserved
3. Time Frog Color: stupid side quest -- Game Boy Color in a watch, including tiny custom cartridges -- completely impractical

The Idea
As my GBC mods continue to get smaller, and I approach the minimum possible size with the TFC, I think it's time to round out my ever shrinking amphibian themed family with the smallest practically usable GBC I can imagine. And so, I'm Introducing the Egg Boy Color: the answer to the question, "what if Benjamin Button, but Game Boy?"

Key Features

• Built using original Game Boy Color CPU and RAM for compatibility with original software
• Compatibility with the same tiny cartridges I designed for the TFC
• Audio output via speaker
• Custom tiny buttons
• Small enough to reasonably fit on a keychain

Stretch Goals

• Magnetic charging dock using pogo connections
• Link port support over aforementioned pogo connections

Worklog
For ease of reading, I will post a summary of worklog entries in this main post in addition to more fleshed out ones as separate posts.

Project kickoff! Started working on the main shell design, both front and back. Front shell is designed around a 1.54" 320x320 IPS screen so I can get a clean 2x upscale on the GBC video.
