I recently bought an external HD and installed the homebrew channel on my wii using the ModMii installation guide. I was able to launch a couple applications from my SD card (Homebrew browser, a couple homebrew games), but when I used Modmii to make apps loadable from my external HD, (Formated it to Fat32 and copy/pasted all the given files into the root of the folder) nothing would show up. I had placed the Configurable USB loader on there, and a Gameboy emulator, but neither was showing up on the HBC. I then placed the USB loader on my SD card, and I was able to launch it and play a game from my USB drive. I realize this might be because my HD isn't compatible with the HBC, but is it possible I did something wrong that could have messed up the HBC or the HD? Also, is there any way I can launch apps stored on my USB drive, through something stored on my SD card, similar to the USB backup loader? My SD is quite small, but I plan to do a bit of emulation in the future, and it wouldn't be able to hold all the roms. Is there any way I can launch a loader from the SD that would be able to access files on the USB for loading, instead of on the SD card?
