What are you talking about? USBLoaderGX is supposed to suport ext2/3/4, and wiiflow has a config string inside of the information at the bottom of the ini file. I changed it and it shows it, andthen immediately crashes upon trying t start it up.
I have a pny 128gb flash drive, MplayerCE works fine, wiimc works fine, so does vgbagx, fceugx, all of the other emulators work just fine. Only the usb loaders don't work. And I don't do ntfs because ntfs is utter and complete garbage in terms of a fs. I always do an ext* based filesystem for my flash drives unless I absolutely must use them with something else.
I am currently on real wii, I did have r1200 or something, originally. It's on the left-hand port with the wii sitting in it's stand thingy. I'm pretty sure that that's port0 as it's the one that worksmost with the rest of the homebrews. Also I don't know why it wouldn't work, it supports the complete usb3 specification and only the backup loaders don't work. All of the homewbrew media players work jut fine, and eve nintendon'tloads teh games jut fine from the games folder.
It's ios249 whatever was required/told to be used when Installed it. I also had to get an updated usb2.0 ios according to ninendon't.
R1188 actually shows the games, but immediately upon trying to start them. It ends up doing the same thing that Wiiflow does, which is locking up the wii, and near-constantly doing something on the flash drive. I went all the way back there and then it behaves like wiiflow.
Edit: With r1218. And then me using one of my ow rips that I redid for testing this. fat32 drive, wbfs Wii Sports. WiiFlow gets to the "make sure you have the strap around your arm" screen and then freezes. USB freezes immediately.
I believe I have a launch wii or very very close to it anyway as I got it pretty early on. Copyright 2006 on the bottom of it. And I got it only a little while after tp came out.
