Dolphin, the GameCube and Wii emulator - Forums

Hey guys! I am new here and have a couple of questions that I am hoping you could answer:
1. Do you need a wii for it be legal to rip the images? I will still have the wii games, of course.
2. Currently building a new system and am wondering what CPU is better for a Dolphin build -> i5 750 vs the new AMD Phenom II X4 665 BE C3 revision
3. Where can I find a DVD drive that can read the Wii games?
4. Do you need a seperate sensor bar to use the Wii-motes on your PC? If so, is there a sensor bar that is USB compatible?

Thanks in advance!

1_ As I understand , no . You only need a legal copy of the games ( the wii only make things easier )
3_That are difficult to find , but you can dump your games to your hdd . see this http://forums.dolphin-emu.org/thread-2900.html
4_ If you need a sensor bar try a wireless one. But if you use two candles It will work too

Sorry , I don't know about AMD CPUs
