Okay, that's not a valid NAND backup. No idea what it is. One last thing that you can try:
- Dump a valid EmuNAND backup using EmuNAND9
- Maker a backup of your corrupt one
- Overwrite the first (exactly!) 512 (=0x200) bytes of your corrupt one with the first 512 bytes from the valid one
- Now try to inject that (altered corrupt) one into the EmuNAND.
