I'm looking to buy my brother a Wii for his birthday, and was hoping to mod it with a Cyclowiz chip. Are the latest versions of Wii still hackable? I remember there being a big deal with newer Wii versions that weren't compatible with modchips a while back. Also, what tools are required to mod a Wii? I know that the chip needs to be soldered on, so I have that down. Do I need a special screwdriver to open the thing?
