iTouchDS firmware v2.3b off GBAtemp + ExpLoader. Both older versions prior to the exclusion and the new 0.58b patched are freezing up. They will do as much as detect the EZflash's presence, 58b will say the hardware is NOW available, then, all versions reach the 'initializing' screen. There, they freeze up. My Supercard has no issues operating the EZ. I've tried scanning the microSD for errors, reformatted from FAT16 32K to FAT32 4K, deleted the ini and emptied the GBA folder. It just won't work. Other homebrew like MoonShell 1 and 2, DSOrganize and commercial ROMs run fine.
