OK - the search is a nightmare to find what I'm looking for, and wading through 100s of posts of mis-information is doing my head in. So. I have a PAL Wii, I ONLY play PAL games. I don't care about homebrew, I will only play backups from the DVD drive. Can I update, are there any issues with upgrading the firmware if I'm only ever going to be using a drive chip to play back-ups?
