The custom paths for most folders list "usb8:"
usb8 is a symptom of no drive found at launch.
when booting into the loader, it mounts the SD card to search for a suitable partition to load a config file.
if it can't find one, it checks on USB if there's one (the first found takes priority, because some users don't want to use SD, but place everything on their USB : games, but also homebrew, the usb1:/apps/ folder)
if the first partition doesn't contain a config file, it checks the second partition, up to 8th partitions (up to 4 primary partitions, on two USB ports).
if no config is found, it should go back to the first compatible partition to create one (usually SD). but it seems to fail to find a suitable partition.
What's strange is that you still have games displayed, so your USB is compatible.
Maybe not the expected partition format for the config ?
@blackb0x :
I updated cucholix's thread. I added an update message and linked to your vWii UNEO version.
it's the direct link. I think it would be better to point to a place where all next releases will be located too, so the link is not outdated on next change or fix. But if it works, I guess it's ok for years now.
A version number or a date in the filename would have been usefull to know which version is newer. Dimok and me last forwarder release was 5.1
