So I installed Homebrew on my Wii via Letterbomb and works fine. 4.3U, I'm able to play discs and games from my USB and SD card. I did the same thing to my friends Wii, 4.3U, using Letterbomb, and h is having issues. When trying to play a disc he receives the message "In order to use this software you must perform a system update." He's already on 4.3. Additionally, when trying to install this game to the USB via USB Loader GX, it freezes mid installation. Any suggestions? Will be posting a syscheck shortly.
