Someone just taught a Dreamcast memory card to do wireless Game Boy multiplayer. The project centers on 8BitMods’ VMUPro, a modern replacement for Sega’s original VMU that already plays Game Boy and other 8-bit titles via onboard emulators. The latest trick is upcoming wireless “link cable” support, letting two VMUPros talk to each other and emulate classic Game Boy link play without a cable in sight. Think Tetris battles or Pokémon trades, but on a postage stamp‑sized Dreamcast accessory that was never meant to do any of this.
For those not in the know, the VMUPro isn’t just a fancy memory card; it’s a full modern rebuild of the Dreamcast VMU with a dual‑core 240MHz brain and microSD support, letting you juggle thousands of virtual memory cards instead of hoarding plastic. It also doubles as a legit tiny handheld, running original VMU titles, 8-bit system emulators, homebrew apps, and even MP3s, all managed via its own store and custom SDK.
Instead of plugging two bricks together with that iconic purple cable, the VMUPro units connect wirelessly and sync their Game Boy emulation states for multiplayer. It’s not just a cute proof of concept either: 8BitMods is pitching this as a proper feature update for existing VMUPro owners, on top of things like Wi‑Fi save management, and all of the features described above.
Dreamcast fans were already spoiled with HDMI mods, ODEs, and fancy replacement VMUs; now they’re getting cross‑platform handheld weirdness bolted on for good measure. It also one‑ups a lot of “modern” Game Boy solutions by doing cable‑free multiplayer in a form factor you can literally park back inside a Dreamcast controller when you’re done.
If you had a VMUPro right now, what’s the first Game Boy game you’d want to play wirelessly on that tiny screen?

Terrible article…it was as you were handed an r36s after never knowing it existed, and was told to rewrite the steps on the archR GitHub page. You didn’t even talk about what makes this special or different.
Not all clones are supported, and performance at the moment is pretty abysmal since it’s an early release.
You need to mention this at the start of the article before someone else wastes their day like I did.
