Cannot get Dios Mios to work; repeated "apploader" errors.
I recently re-modded my Wii, following the instructions in the "Softmod Any Wii" guide, and it went wonderfully, with everything installing and working as I hoped it to. I can play Wii games without a problem via USB. The reason I even re-modded, though, was because my little brother wants to be able to play again some of the Gamecube games we had ages ago but don't work anymore or have been lost. So I tried to install Dios Mios Lite, as per the instructions in its respective guide.
Here's where I started running into issues.
I followed the instructions and put Luigi's Mansion on the SD card, in its proper directory and everything. The guide I followed linked to DML 2.2, I believe (though as I understand it there is a 2.6), and my USB Launcher GX is 3.0, if that helps any. The channel icon for Luigi's Mansion appears fine, and I tried to click it and press start. The Dios Mios logo, as well as the GameCube logo, both appear, but then are followed by a rather disheartening error of some sort. I've obtained 3 such errors so far; the one currently splashed across my screen says "Fatal error apploader size is zero!". There is a retail disc in the tray at the moment, Twilight Princess. I tried without a disc in as well, I got a different error that I don't remember.
I haven't tried updating DML to 2.6, but I did download and install regular Dios Mios 2.6 and uninstalled DML 2.2. For the record, I don't remember which IOS it was that I used, if that matters.
After installing DM 2.6, I put Luigi's Mansion and Metroid Prime on my USB hard drive, plugged it into the lower slot, booted up USB Launcher GX. Luigi's Mansion and Metroid Prime are still channels, but when I click them it tells me that the games are on the USB and it asks me if I want to move them to the SD card or not. The other options are "Cancel" and "View SD Card", or perhaps it's "Delete SD Card", one of the two. There is no option to play from USB, which, as I understand, is the entire point of regular DM.
I'm no expert with this kind of stuff, I'll be honest. But it's frustrating to know that I can follow instructions to the letter and still wind up hopelessly wrong and not know where I went astray.
Any help would be appreciated! I've been up all night trying to do this for my brother and I'm going to get some sleep for now.
