I was playing the Legend of Zelda Wind Waker with my GBA SP plugged into my Gamecube and it started to run out of juice. So I quickly ran down to the fridge and pulled out some orange juice! I poured it in a glass and ran to the poor thing. Acting quickly I sat down at my desk and started this up!
Step 1: Materials
You will need a Game Boy Advance SP, a GBA to Gamecube cord, A Phillips screwdriver, and something to pry it apart which could be a knife, a screwdriver, or a multi-tool!
Step 2: Dis-asemble
First you have to take the adapter apart, just take out the screws.
Step 3: The Insides
This is the insides of the adapter. All you need to do is just pull the electronics out!
Step 4: The Needed Piece
This is the only part you need so you can just throw the rest away!
Step 5: Plug It In, Plug It In!
Video of proof!
