I'm currently developing a GameBoy Color Emulator for learning purposes. I also wanted to emulate the GameLink functionality (poké-fight ftw!), but I did not found any documentation, examples, references or source snippets on how to emulate the GameLink.
All GameBoy emulators I found on github didn't provide this functionality.
Programming Language doesn't matter, I'm just curious if there are resources on that topic out there.
Has anybody an idea on where to start with this feature?
A few links that might prove useful :

The key appears to be to search G for gameboy gamelink protocol.
Apologies if you already know of them
