I have one of the original Wii's from when they first come out. It is a PAL system. It is currently getting modded professionally, with the Wiikey. I have been looking through the forums to clear up a few things but getting really confused. I am just looking to play a few games that have been backed up. Fistly I see there is update images (currently 1.9b) and setup disc images (currently v1.3). I know that the Wiikey can be updated, but I am unsure of the difference between the two images and what each of them does. Secondly why is it important that the Wiikey is updated. Thirdly does the system firmware have any effect. Can I still upgrade it via the internet with the Wiikey installed. I guess to sumerise I just want to know what I should do, and in what order, when I get my Wii back to play latest backups of games. Thank you in advance for any help!
