WeirdBoy Mini: Retro NFC Keychain

Let’s be honest—blowing into a cartridge probably never worked, but we all did it anyway.

WeirdBoy Mini: Retro NFC Keychain
is kind of like that:

A small, fun nostalgia that lives on your keyring.

Tap it, and it launches your favorite retro game (already on your phone).
It’s silly, it’s simple, and it was made with love.

Works like a real-life cartridge
with a modern twist!

A miniature Game Boy-inspired cartridge that’s secretly a smart shortcut to your favorite retro games (Game Boy and Game Boy Color classics) via Delta Emulator* on iOS. It looks like it came straight from 1989, but it’s powered by modern NFC tech. With a quick tap, this little cart brings your handheld memories back to life — no blowing required!

It’s not high-tech, but it’s a satisfying little moment
that brings back big memories.

Originally created as a bonus item for the WeirdBoy Case project — a handmade Game Boy-style case — this little cart got so much love we had to release it solo! Check out Homepage to learn more, join the waiting list, or support the project on Ko-fi. ☕️
