Working in the lab. Not released yet.
Tell me when it's readyHow it works
- The Chromatic has Wi-Fi built in. Shiny Relay uses that chip to carry the link cable.
- The link port talks to Wi-Fi. When a game sends a byte over the link cable, the Chromatic sends it to the other player over your network, and brings their byte back.
- Unmodified games just work. The game thinks a cable is plugged in. Nothing on the cartridge is patched or changed.
- It is a firmware install. Shiny Relay runs as custom firmware on the Chromatic's FPGA and its ESP32 Wi-Fi chip. The stock firmware can be restored.
What works so far
Tested on a real Chromatic over home Wi-Fi. Honest list, nothing more.
- DoneLink test, both directions: 0 errors.
- DoneTetris DX 2-player matches over home Wi-Fi, from start to finish. The other player was a computer running the other side of the link.

- NextChromatic to Chromatic on two real units.

Questions
Does it need a mod?
Yes, a firmware one. Shiny Relay is custom firmware for the Chromatic's FPGA and its ESP32 Wi-Fi chip, so it is an install, not a plug-in accessory. The stock firmware can be restored.
Which games work?
Games that use the link cable. Turn-based ones work best, like trades and battles. Every byte crosses the network and back, so fast real-time link games can run slower than over a cable.
Is it free?
Yes. Shiny Relay is free.
Does it change my games or cartridges?
No. Games run unmodified. The game talks to the link port as usual, and the Chromatic carries it over Wi-Fi.
Does it work on other handhelds?
No. It uses the Wi-Fi chip inside the ModRetro Chromatic, so it is for the Chromatic only.
When will it be ready?
There is no date yet. It works in the lab today, and we will release it once it is ready for other people to install. Leave your email above and we will tell you.
Who makes it?
Shiny Gen, the app for making GBC games with AI. Shiny Relay is not made by ModRetro or Nintendo.
