Thanks to everybody's advice I've revised my plan for SMG:
[Current situation: PAL wii 3.0E with wiikey 1.9g updated]
1. Wait til I can update my PAL wii to 3.1E (go to my mate's house tomorrow)
2. Download SMG (done), extract iso and burn. No regionfrii, no brickblocker.
3. Insert disc, start SMG update, unplug at 10%.
4. Restart wii. Play SMG.
5. Mid-November, download PAL SMG and run PAL update.
Is there anything I'm missing out ?(still not too sure whether regionfrii should or shouldn't be used)
Don't forget to apply the brickblocker to the 2nd copy.
Ah! I knew there was something!
Thanks!!
