I'm pretty sure you've hex edited files before, so I'll throw this out there: hbl2hbc.elf uses sd:/hbl2hbc.txt because that's what's hard coded. You could put multiple copies of the elf in different SD:/wiiu/apps directories, then hex edit each elf to use a different txt file, like sd:/hbl2hb1.txt, sd:/hbl2hb2.txt... Just make sure you overwrite the filename characters and don't insert or delete any.I wasn't aware as well that it has to be on SD root.
That means we're limited to just one HBL2HBC?
I know that we can put multiple vWii channels in the txt file but I wanted separated HBL2HBC icons to launch separated vWii channels.
The file name is at 0x15064 in hbl2hbc.elf v1.1u1
