Anyone know how to run nes, snes, n64 games as channels?

Games that I've bought from the Wii Shop Channel show up on my Wii home menu as seperate channels. I was wondering if there was any way to get the games on my SD card (which I'm currently using snes9xgx to run) to show up as seperate channels, like the Shop Channel ones.

There is, but it's not really worth the effort. You have to dump one of you existing SNES VC games (i.e. one of the ones you purchased), edit the banner and replace the ROM, repack it, and then install it. Editing the banner is a bit of a hassle, and the whole process can be a bit buggy I think. You're honestly better to just stick with snes9xgx. You can install a channel to load snes9xgx if you want to be able to access it a bit faster.

Like SifJar said, you should just stick with the emulators. It's easier and you don't have to worry about messing up anything on your wii.
