You can use WiiScrubber to extract/import files single files.
You can also use Wit/wwt tools, but they are command line only.
another way is to do it on the console, with WiixPlorer you can browse your disc's content (if you have the disc, of course)
ah, sorry
So, you already have the bin files and you want to convert/open them in a program to view the models.
a lot of game uses the Szs format for 3D models/textures, there are programs used to open/edit them. maybe you can try one.
Look for Szs Modifier, or Szs tools.
But some games have proprietary format, and you'll need specific tools (maybe not written yet).
Sorry, I can't help more, I don't do game modding and model editing. Other users might help you.
