Hi experts/gurus. I have a hacked 3.2u japanese wii that displays in english and can play backup game discs, but can't play newer games eg. iron man2 or motion plus games. I've googled and found few youtube tutorials etc. to hack the wii, but mostly are relating to system menu version 4.0 as a prerequisite. But my version is 3.2u. Do I need to upgrade to 4.0? If so, how? There are so much information out there but none that addresses my particular version and worried about bricking. Please help.
