Alright. I feel that I've tried every thing (and every combination of things) that I've found or read about on any forum I could find on this topic. I run my Wii backups from USB, of course, so I thought I'd set the GC games on an SD. Originally I tried with a 2g FAT32 with 32kb cluster, with Dios Mios Lite. I tried on both IOS249 and IOS236, got this error. Switched to Dios Mios with USB, same same for formats, one IOS then the other, same error. Switched to SDHC, 32gig with 32 or 64 kb clusters, IOS249, then IOS236, back to DMLite....same error. Yes, the games are in the "games" folder and have been optimized (tried various programs for this but are currently optimized by DiscEX). I've tried using DMLizard and installing both the DML wad and the RVL-BC-V6 wad. I've tried DMToolbox. I've tried using NeoGamma, WiiFlow, USB Loader GX, ConfigUSBLoader, and ConfigUSBLoaderMOD. I've tried reformatting, reinstalling, etc. a number of times. I've tried a differed USB drive and different SD cards. I always get the exact same error. Did I miss something? Help!!
