So I recently bought an old wii, specifically for the purpose of homebrewing. I’m able to understand so far as to what needs downloaded on the Wii and how to backup, but I can’t find any sites with games. I noticed Vimms Lair wasn’t an option anymore, and other sites I look through use ROMs for emulators. (Unless, those do work on the console). I think you need .wbfs files, and I’d really appreciate if I was pointed in the right direction
I think you’ll download .iso’s, then convert them to .wbfs using Wii backup manager, which should also manage the folder structure / transfer to your SD card. I don’t think the console needs .wbfs per se - it’s the method you choose for running the backups which determines format restrictions instead - but Wii backup manager was fairly straightforward to use in my recollection so that should be a good option.
There might be some repository online already in .wbfs, it just used to be standard to convert from an .iso because that’s the standard container a disc backup will be dumped into. There’s nothing too special about .wbfs other than it omits the garbage data included in retail disc backup .iso’s to pad the discs to 4.3gb, so .wbfs will be smaller
