Yeah. Remember, Freecycle!
Its a gay yahoo groups thing, but the stuff you can get through it, its worth putting up with a substandard forum for it.
Just thinking of doing a USB Flash Stick, yet both that I've got here as spares, both have a CDFS partition, which needs removed. WBFS doesn't see the drives either, so that sucks.
So back to the SDHC card for ease atm.
If this is any help to anyone, hears a simpler way i used to get this going.
1 - Just get any SD card at least 512mb or over. Insert into your pc or reader and right click and format the card to fat32.
2 - Open WBFS 3.0 available on first post and then format the card with it. You should be able to see your card even if its in a reader connected to your pc as a removable device.
3 - Next using WBFS 3.0 just add the NSMB iso and load to the card. This will show as 0.34gb. It is important here to use the iso that is stripped of its protection, this is the one i used available on most torrent sites.
4 - Then insert card into Wii and turn it on. Use neogamma 7 and select SD/HC card and press A. Then select Mario game and all works well.
