Slop-free Wii library managing

I recently acquired some Wii games, and I wanted them on my USB hard drive to avoid damaging the discs.

Since the last time I had to do something like this, I switched platforms, I went to wii.hacks.guide, only to discover that what they recommended was slopware:

wii.hacks.guide page for managing backups

Since all I really care about is making WBFS files so they fit on my FAT32-formatted drive, I don't need a full-fledged GUI anyway, so I did some digging and here's what I found.

Note: This is fairly GNU/Linux-centric. Windows or macOS users might be able to replicate this, but I provide no guarantees.

Prerequesites

• "cat" and optionally "md5sum" and "sha1sum" for hash verification
• Wiimms ISO Tools (WIT) (you can check Repology to see if your operating system packages it)
• A file manager
• A homebrewed Wii with a USB loader set up (you can use wii.hacks.guide as a reference)

Wiimms ISO Tools (WIT)

Since I'm running Alpine, I made a Debian 13 distrobox, because I'm lazy.

Making an ISO

If your ISO is in parts, you can just follow wii.hacks.guide:

Jointing PART files in wii.hacks.guide

Alternatively, run the following command, with "<ID>" being replaced with the ID of the game you're making a backup for:

cat <ID>.part0.iso <ID>.part1.iso > <ID>.iso

Then (optionally) run the following commands to verify the ISO hashes with the dump information in "<ID>-dumpinfo.txt":

md5sum <ID>.iso
sha1sum <ID>.iso

You can also use a GUI, such as Collision, to verify the hashes:

Making a WBFS file from an ISO

Make sure WIT is installed, then run the following:

wit copy --wbfs <ID>.iso <ID>.wbfs

In most cases, the resulting WBFS file will be suitable for use. If not, you can look at the documentation for help:

WIT copy command documentation

Moving the WBFS file to a hard drive

Look at the required directory structure, and just copy that:

Game Folder Structure

That's about it!
