well, its a 2017 video but is providing prehistoric info.
wbfs manager? its known to corrupt drives
cios236? it is not needed anymore
cios r20b? it is more than 8 years old and latest stable is d2x (aka r21) rev8/9 or beta 52/53 for vWii.
usbloadergx without rev info on boot screen? very outdated.
you are on a Wii right?, so bottom port is actually port 0 (reverse of vWii), so you were using the wrong port all along...
I noticed from the start of the video and was very well aware that it was outdated. I knew that I would probably end up having to update a few stuff and make corrections, but hey, atleast it worked. I later had formatted back to FAT32 anyway because I wanted to use Nintendont as well.
