I have a discussion posted in the Backup Loaders forum which shows the progression of my problem: http://gbatemp.net/index.php?showtopic=180977 But here's the summary: I received a Wii from someone who had a previous Twilight Princess hack installed. I performed xzxero's simplistic Wii mod (found here: http://gbatemp.net/index.php?showtopic=171901), and made sure to perform each step carefully and to the letter. So whatever is done there is what is currently done to my Wii, with the files he provided. Here's what I've found. Certain games I've downloaded will not work on my external hard drives (I've tried two: an Adata CH91 320GB external, and a Western Digital Passport Essential 320GB external), but will conversely work fine when I burn them to DVD. I so far have succeeded twice in this, with the games Super Mario Galaxy and Punch-Out!! Wii (there could be more, but I ran out of discs). But this is where it gets even more interesting: certain games will run fine on my drives! There are three confirmed so far (which actually let me play the game without freezing): Metroid Prime Trilogy (using alt-dol), Elebits, and Resident Evil: The Umbrella Chronicles. Here's an example of what will happen: I'll put Super Mario Galaxy on my drive, I will go to load it, and I will notice the light on my Wiimote shut off for a second, then turn back on. The screen remains blank, and never progresses from this point. With Punch-Out!! Wii, I get to the screen where it says "Loading..." at the bottom right, but it hangs indefinitely on that screen as well, whereas the disc copy I have loads within about 4-5 seconds. So now I'll provide as much info as I can about my Wii, and hopefully someone out there can provide me with a solution! - System firmware 4.1U - cIOS v14 (have also tried 222 and 223 options in games, instead of 249, but none of those work either) - Apps used: NeoGamma R7, USB Loader GX, Configurable USB Loader (all default settings) - preloader has all system hacks activated. Disabling them does not help. - Using WBFS Manager 3.0 in Windows XP through Boot Camp on my 2008 Intel iMac (the ISOs are stored on my Mac partition, and I normally just point WBFS Manager to the Mac side, but I have went as far as copying some ISOs to the XP partition before adding to WBFS Manager, and this did nothing) - certain ISOs have been pre-scrubbed, but I am not sure which ones, or if that has an affect on the proceedings I will happily provide any further info needed in order to get this solved. Someone, ANYONE, please help me out!
