Game Boy Color on My Conference Badge

Summary

At GitHub Universe, Simon Willison revisited the conference badge, a programmable color-screen computer. He met Steve Francia, who used Gemini to get a full NES emulator running on the badge and then went further with Game Boy and Game Boy Color emulators, meaning Zelda: Link's Awakening can run on it given a ROM. Flipping the badge upside down exposes built-in touch game controls.

Game Boy Color on My Conference Badge. I'm at GitHub Universe this week and, similar to last year, the conference badge is a full-blown color screen computer.

I've been hacking around with it again, and then I ran into with Steve Francia... who worked with Gemini to get a full NES emulator working on it, and then went a step further and deployed an emulator for both the Game Boy and the Game Boy Color.

Which means, if you can obtain the ROM, you can run The Legend of Zelda: Link's Awakening on your conference badge!

A neat feature of the badge is that you can turn it upside down and then use game controller touch buttons that are built into the badge body.
