Are you talking about backing up Wii game discs or generic discs (e.g. Iso 9660)?
If it’s just Wii software I know there is something available which uses the web browser, which I’ve used myself but can’t recall the name of, but I wouldn’t recommend it as there’s no checksum verification.
The tool is on wii.guide
https://wii.guide/dump-games.html (To PC over network)
But honestly I would prefer CleanRip for dumping games to SD or USB.
======
For the purpose of backing up arbitrary DVDs (non Wii/GC discs): If you don't have any optical drive in the house,
please order an external DVD±RW drive. They are dirt cheap and it will work much faster, much more reliably and can read (and write!) CDs as well (Wii can't).
Reading DVD±R with a Wii can cause major frustration and DVD±RW may even be impossible (depending on your Wii drive – they are picky).
========
Anyway, I have to test this: No idea what is going to happen:
I inserted a pressed Windows 7 Ultimate installation DVD into the Wii and lied to the dumping program saying it is a Wii DVD. It mounted the disc (without name) and offers downloading "
.iso" . But it says the file has the full 4.3GB (like a Wii disc with padding). This will take forever; even with wired (Ethernet) connection the dumping process is slow as a snail (about 435KB/s). Is this going to be a functional Windows iso or will it crash once it reaches the end of data on the disc (about 3GB)??
Edit 1:
Maybe ftpIi is an option. Will try that as well later. Copied 800MB at the moment.
WiiXplorer-SS should have an ftp server as well (but my WiiXplorer crashed when trying to open the Windows DVD)
Edit 2:
The file loaded while I was away from home with the full 4.3GB which doesn't make sense (maybe it is padded with zeroes), but it can be mounted with
mount -o loop win7.iso /mnt
I didn't try if that iso image really works for installing Windows. If so, the
truncate command should be able to trim it. I will continue tomorrow with testing ftpii and WiiXplorer-SS.
Edit 3:
Now to ftpii:
Filezilla is able to connect without problems and the transfer rate is a little better (about 8 MBits/s).
- Windows 7 DVD failed. Seems the UDF file system isn't supported. Maybe that is why WiiXplorer crashed when trying to open the Windows DVD.
- Tried a PC game disc (Sims 3) but ftpii gave an error when trying to mount it. Strange it is a standard DVD as far as I can tell
- Unprotected (non-CSS) pressed video DVD is mounted right now and I'm pulling one of the VOB files.
It already gave one crash (stackdump) on Wii when trying to pull a NAND backup from SD.
For now I would say ftpii is a possibility to extract individual files from DVD (ISO9660). It requires patience. DVD video decryptors should be able to use the encrypted files that can be copied from CSS video DVD.
