Ok, I am so embarrassed for asking something once again but I read the ReadMii and I thought this would be cool!
[1c] [Optional]Autobooting and returning to USB Loader GX
It is possible to boot your wii directly into the USB loader GX. The only thing you need for this is a wii app called preloader. First download the newest rev of the loader or even better, the forwarder (dol format, see downloads at the top of the readmii). Place the dol you get in the root of your SD card (no need to rename it to boot.dol). In the preloader menu, choose install file and choose the dol to install. When its done, go to the main menu of preloader (B) and then choose 'settings'. You have to change 2 options here: Autoboot=file and Return to=preloader. Save the settings, then launch the Wii menu in the main menu. It will boot into the USB loader GX!
Anyway, it works pretty good. Though I cannot get into the Wii system anymore because it directly boots to the USB loader
And I couldn't find the preloader config on the SD card, do you know where it is so I change it a little?
It does return to preloader, but preloader is set to autoboot the file so it doesn't make much sense. If autoboot= file then return to preloader = autoboot.
