Duplicate Channel Remover's boot.elf

[Antibiotics]

I'm throwing my console away, but I wanted to preserve all of its content before doing so. I copied the NAND to Dolphin, and it works. It, however, has two duplicate channels, and I want to erase them. Since HBC is broken, I'm trying to simply open the app with "Open", but I get a black screen. Any other way to remove these duplicate channels is welcome, too. I don't want to do it on my Wii and copy the NAND again for various reasons.
