Game Boy signer

[alexgleason]

This is impractical. Just a thing I want to exist. I want a Game Boy cartridge that stores your nsec in the game save and can sign Nostr events over a link cable. You plug it into USB with a link cable adapter, and then use WebUSB to sign events. NIP-07 browser extensions could add Game Boy support.

Why? 1) it would be funny, 2) a lot of people have Game Boys.

Someone made it so you can trade and battle Pokemon through a Chrome extension using a link cable. https://pepijndevos.nl/TCPoke/

So the hardware side of this has been done before. Just missing the software.

It's amazing how far someone got with the wrong idea: https://www.theverge.com/tldr/2021/3/29/22356862/mining-bitcoin-game-boy-gpu-shortage-raspberry-pi-pico-mod

It's kind of mind blowing.

Id be willing to work with someone on porting my noscrypt library

I've been working on making a remote signer with the PlayStation Portable. I'm currently blocked on getting TLS sockets working, I'm looking into it -- after that noscrypt should just be able to be dropped in if it doesn't have too many weird dependencies.

As much as I would love that, I doubt it 😆. It depends on libc, libsecp256k1 and openssl or mbedtls, if you are already using mbedtls should be much easier.
