for various technical reasons there wont be any official scummvm channel. the homebrew channel addresses all of these in a reusable way, so i dont see any reason to not use it to launch any application on a wii.
if you dont want to install the hbc on your wii you can also load it with just the
twilight hack or some other
loader.
And yes, you can also inject the scummvm wii binary into an iso, burn it and thus load it from a dvd-r(w) if you have a modchip. but that approach relies on the signing bug (aka trucha), which got fixed with the
system menu v3.3 update.
If you still think that this is worth it, you might wanna take a look at
this template we used for the hbc install dvd.
my advice: just use hbc
