An open-source DIY link cable for the Tiger game.com handheld.
You can use an Ethernet cable as a "base" and cut off the connectors. The Ethernet cable has 8 wires, but you only need 7, so you can remove one. Push the Ethernet cable already through the connector part and then solder onto the PCB. The PCB side with 4 connector pads to the game.com link port needs to face towards the Ethernet cable shell part. Connect the solder pads as follows between the two ends:
| Pad End A | Pad End B |
|---|---|
| U1 | U8 |
| U3 | U3 |
| U5 | U6 |
| U6 | U5 |
| U7 | U9 |
| U8 | U1 |
| U9 | U7 |
Pads U2 and U4 remain unconnected. Many thanks to Xiden for providing the pinout of the original compete.com link cable!
The PCB is 4 layer and should be ordered with ENIG and 1.0 mm width.
The STL files for the shell can be found inside the STL folder. I'm not 100% happy with the design/fit, but it's working for me. Anybody who is eager tweak it is obviously welcome to improve it :) .
Use the files to build your own link cable at your own risk. This adapter works fine for me, but it's a simple hobby project, so there is no liability for errors in the board files and/or shell design. Use at your own risk.
