3rd party Gameboy online adapter.

I've been wondering if this is a thing since technically the link cable is a LAN cable for Gameboy so what if there was a link cable that connected to a USB port and a program that connected it to a friend using the same cable over the internet. I'd love to play GB and GBC games with other people out there who still play them.

The Game Boy Color was capable of online connectivity, but I'm not sure about the GBA. Maybe if you somehow reprogram the japanese GBC games and make a custom server...?
