The original Super GameBoy cartridge did not have a link port for multiplayer gaming, like the later Super GameBoy 2 cartridge did. This board allows you to add a link port without having to destroy an existing console. This board uses a GBA-style connector, because that's the only one I'm able to source as new parts at this point. The GBA link port is fully compatible with GBC link cables, which is what the SGB2 used for its port. GBA cables, however, will not work (even though they will physically fit into the port).

This mod is intended to be paired with the SGB Clock Mod, otherwise the incorrect clock speed may cause desyncs when paired with properly-clocked consoles.

The Flex PCB adapter is an optional add-on which makes installation much easier. It is not necessary, but installing this mod without it requires manually soldering several wires directly to the small pins on the CPU.
