When they built in an wasabi chipset you can update your system anytime
errrrmmmmm thats the one they built in in Thomas WII.
Burned about 50 games now and they all work,
I used Imageburn too but you also need a second tool (wiU 1.1) to remove the update from the isofile!!!
And burn the dvd`s on verbatin - dvd!!! thats the advice I got and what works for everybody that I know who do it.
You can try to burn it on a dvdRW to check if it works but not all WII will accept the dvdrw
