Can some body tell me CIOS version which supports both wiigator gamma launcher and USB Loader 1.5. As wiigator gamma launcher comes with its own CIOS. Which CIOS version is supported by both. I can run backups from wiigator gamma launcher , but when I run USB Loader 1.5, it gives me error ret=-1 instantly. I tried it both with SD card and USB drive and USB pen drive, but same error ret=-1. I think it is error of CIOS which does not support USB Loader 1.5. But I am not sure. Please guide me.
