The listing, GBA/GameCube Connection and charger cables has ended.
1) A car power supply with two ports (for two GBA's at once) and a home power supply cable for the Game Boy Advance. The original Advance did not have rechargeable batteries, so these units has a power pack that replaces the battery door and needs an active power supply to work.
2) Two connector cables that allow for system to system play across the Advance/SP and Game Cube/Wii. The silver cable has three tips: two GBA/SP ends and one Game Cube controller end. Since the Wii has Game Cube controller ports, this will work on the Wii, although this will only allow connection between either two GBA's or one + the Game Cube. The silver cord also has a port to connect another GBA connector cable. The blue has two GBA connectors and a port to allow for additional cables.
I have not used these since about 2007 but had worked fine when put into storage. I no longer have a GBA to test them on (since I have a Nintendo DS, I could if I had another system).
Shipping: 10.95 for flat rate medium box or 4.95 for flat rate envelope. I believe that I can safely pack them so they will not break free of it, the winner may chose. Payment via PayPal only
