Hi all. I've been trolling around the forums for a while now, usually not having to post any questions due to the ridiculous amount of research I put in to problems I have. But now I'm stuck. Here's the deal: I was rocking the System Menu 3.2u with Starfall(!) and decided it was time to update since BootMii came out (kinda recently I think). I updated to sysmenu 4.0u, and now have BootMii installed as well as Preloader for the hacks. I also installed Waninkoko's cIOS 13b. Everything's working fine, except for USB Loader. I formatted my 2 Gig SD (MicroSD in an adapter) card using some tools I found on here, and I found 2 games I had would be small when scrubbed, and are on the compatability list as working. The games are Carnival Games and Smarty Pants. Now, I load up USBLoader 1.5, pick to load from the SD slot, and that's where things stop working. Both games when started flash a green screen, and then give me a 'dirty disc' error message. I've tried two other loaders (USB Loader GX & Ultimate USB Loader) thinking maybe one of those would work due to their mods, but they don't even see the card as a device. I also had formatted the card originally with 2 partitions, one with FAT and the other WBFS, but after none of the loaders found it, I reformatted it to just 1 WBFS partition. Still no good. I've spent most of today searching for something about USB Loader and dirty disc errors, but can't seem to find anything. Here are my questions: Is the card most likely not compatible since 2 of the three loaders won't see it? Does the fact that it's a microSD in an Adapter make a difference? I could try other MicroSD cards, or I have a regular SD card around here somewhere I could try. Any reason why USB Loader would see the card, but not the modded versions? If I've missed something obvious, please let me know and I'll reread any documentation I need to. Or if I haven't mentioned something I need to, just ask and I'll give whatever information is needed. In the meantime, I'll try the standard SD card I have (if I can find it) in case it's simply that my MicroSD isn't compatible. Thanks in advance!
