One last set of questions, what are the main differences between this version of WiiFlow and the one found here https://sites.google.com/site/completesg/backup-launchers/usb/wiiflow ?
Also, what are the main differences between Configrable USB loader, WiiFlow and USB loader GX?
I'm currently following this guide: https://sites.google.com/site/completesg/before-you-begin
I find text guides much more reliable.
They all boot Wii games (and GC games when paired with another loader) but WiiFlow and CFG Loader aren't maintained very much anymore. AbdallahTerro and fledge68 here are still supporting forks of WiiFlow, though. USB Loader GX just got updated this week.
If you're following that guide when you get to the cIOS installation don't install the beta53 version of d2x. Just use v8 or v10 beta52. Beta 53 has game compatibility issues.
