Hacking Is there a way to convert a .wbfs or .iso to .wad?

I believe that nintendo implemented a 40MB file-size limit for wiiware

You can do like, channel forwarders that have the same function in the end that you're looking for.

As for a straight-up .wbfs/.iso to .wad packer like you are looking for, while it doesn't exist such a thing would be technically possible to develop. Sure there are obstacles like a disc game's file size usually being larger than the available internal storage, but anything is possible if you believe in yourself.
