I was having trouble running Viewtiful Joe: Revival with Nintendont (weird missing music and other issues) so I gave Devolution a try. I was able to get it working on a physical Wii as follows:
- Get devolution src zip and copy data/loader.bin from that archive to sd:/apps/games/gc_dev/loader.bin (it doesn't seem to be included with binary distribution for some reason)
- Make sure UsbLoader GX had its Devolution loader path pointed at above path (it was by default)
- Use CleanRip to extract the iso and move it to sd:/games/Viewtiful Joe Revival.iso (not subfolder)
- Start up Devolution from HBC and register my disc as normal (insert disc, wait for game to start once with physical disc in the drive)
- Copy the the iso to sd:/games/Viewtiful Joe Revival [GVFJ08]/game.iso (there are now two copies on my sd card, one for Devolution and one for USB Loader)
- Run UsbLoader GX which can now see the game in its list and configure it to start with Devolution
Game seems to run fine on the Wii. I haven't tried getting it to boot on vWii yet but I expect similar process would work after pairing the wiimote, etc.
