Guys, wanted to know one thing.I had a korean Wii and it bricked and i changed the whole motherboard for an american one and the technician added the neo gamma R 9 to launch my disks. From the normal disk lauch disks don't start. It says unable but from neo gamma everything works fine.

Want to know..does my Wii have a chip or is this what is called Soft mod. do you need wii to be chipped to get that to work or you can just add it to any wii to play any games.
Also what other loaders are there similar to Neo gamma that work fine.
Thanks
