aloha Chaos,
Billyhome is right on materials and tools
Before solder though, I'd like you suggest that if you push down firmly w/o breaking the teeth from the modchips you will not need to solder. Try several things:
1) Push firmly down on your mod chip that's on top of the drive, while pushing firmly, try to click the on button, if it turns green. Then you just needed to have the chip firmly placed. What I did to help keep mine is place which btw, is working well is I used the electrical black tape. While pressing firmly, I placed the black tape (around 2.5 inches by 3inches) over the board w/ the dip switches. I made sure the tape was tightly stuck to the board. They dont say it but it truly to me is to aid in securing the adapter. I checked several times w/ a back up before I sealed my wii.
I havent have a problem with it getting loose as of yet, and I have taken it to several of my friends places to play games. Give it a try first.
Let us know which way you choose? Goodluck
