I got this working on a Wii with Wii-key 1.9s.
Wii firmware: 4.2E
Tonight i'll post some guides how i got it working.
Basiclly I installed HBC and cIOS rev14.
Then i launched NeoGammaR8B7 to play the game.
The ISO I used was the non-scrubbed version of 4,x Gb
although i ended up accidentally changing my nand with no way of going back bc i didn't know you needed a gamecube controller to restore it (i have a wii minus/1.1, which doesn't have gamecube controller support)
and if i find the sd card i have my NAND backed up on, i can not only restore the NAND if i solder the right part in, but i can also put my NAND on dolphin, then i can play dolphin online, like PMEX Remix or MKWii Riibalanced
