    Didn’t know what sub to put this on but this just seemed closest I was wondering what Wii Scrubber actually does and if it can extract the SZS files from a rom?

    You can do that as well as scrub "garbage data" as WikiTemp says, if you have Dolphin you can already do this (right-click game, go to Properties, Filesystem tab, and extract data from there)
    A more up-to-date solution (in comparison to WiiScrubber) would be Wiimm's ISO Tools

    It can pull apart Wii ISOs of some flavours (if it is plain iso or scrubbed one then yeah, some of the more exotic stuff it can have troubles with. https://wit.wiimm.de/ if you need the fancy stuff).

    Its main purpose is scrubbing isos and has a few modes there.
    Some explanation.

    Wii isos are encrypted across the whole disc, kind of rare before then but hey.
    Anyway this does also include the blank space between files (your single layer DVD has 4.35 gigs or whatever it was for Nintendo's slight tweak, even if you only use 200 megs then you still have 4.whatever of data).
    This means at the start every iso was 4.whatever gigs and could not be compressed down any further. One game however was noted as not having random and incompressible data in the padding between files and thus could be compressed. As the Wii has better things to be doing than checking the contents of random padding some wondered if then it was all blanked out you could at least compress it down and store that instead as a far smaller file. Turns out you could and indeed the Wii did not care one bit.

    There are a few variations on the theme, normal, safe and reordering or whatever it was called inside it.
    Normal trimmed basically everything it could without disrupting the main game. Safe missed trimming a few things that theoretically could have been detected if Nintendo or whatever had wanted to.
    Reordering... early DVD drive hacks only allowed unmodified games to run. Later after the trucha bug we could run unsigned for people in turn took all the files, slammed them to the front of the iso and this style of scrubbing then needed a software modded wii (basically all will be this today, nobody uses drive mods/chips as the primary method) to run those but got the best compression results.

    Anyway yes Wii Scrubber has the ability to flick files out -- it has to know where and what they are to do its job so was no great effort to also pull files out. It is not its primary purpose but was the go to tool for a long time which is probably why you read an old guide/forum thread/whatever and are asking this.
