I would like to ask for your assistance regarding my friend's wii. He has a PAL version(bought from Australia) and would like to have it converted to NTSC. My question is, are all the Motherboards of the Wii the same hardware-wise? Are the contents of the NAND the only thing that is different between the different regions? As far as i know back in the Gamecube days, the motherboard was different for the US, Japan and PAL versions. I could of course run US gamecube games from the Japan version using a mod-chip but for the PAL version, it was also running but in black and white. Plus i had to solder some wires to make a Japan to USA switch. If i use Any Region changer (which i have used to convert Japan and Korean region versions to USA NTSC), will I successfully be able to convert it to a USA version (NTSC video, USA Region, USA language) without any problems? Thank for your insights/input regarding this inquiry.
