We had a cable go bad on us, and I could never find a replacement. Finally, I saw the wireless device. I bought this for my daughter. She and I play pokemon on GBA. We no longer have to be within cable reach. but at least in the same room. Matter of fact, we have more fun now. The wireless is faster than cable. Its easy to put on and take off. You can hook up with multiple players using the wireless.
Note, you can't use the wireless and cable, its either/or. Also, with GBA, you have to have the newer games that says wireless. Its not backwards compatible. Recommend this device and the GBA TV Adapter.
