    If you unscrub (uncompress) a scrubbed (compressed) wii ISO through WiiScrubber, after using WinRar to extract is the quality better (i.e. video speed, game speed, sound, load time, etc.)?

    Thanks in advance~

    Scrubbed just mean they swap non compressable garbage data with zeros which are compressable garbage data. Where as trimmed/riped that means something was removed and that usually the update partitions.

    I wouldn't be surprised if some of the scrubbed isos are brickcrapped, but in general: scrubbed == data that is not used anyways is removed. The .iso is still 4.x GB, because the data should be at the end of the disc to allow faster reading. But scrubbed .isos can be compressed to their real size, while regular .isos can't be compressed under 4.x GB, even if it's Wii Play that is 200(?) MB big.

    How do you explain CLiiCHE's Resident Evil Archives release, compressed to 3.52 Gb? it always confused me, as it's definitely not scrubbed. I've compared the ISOs, even scrubbed it after extraction and got a much smaller ISO, one of the same size of the other scrubbed releases of the game.

    There's no difference in 'quality'. The only difference is the speed of downloading.

    And technically, scrubbing isn't just compressing. It's getting rid of useless files, then compressing.

    EDIT: I just remembered: some games (dual layer) have lots of problems when scrubbed.

    Yes but I don't really think they can be counted as they are unique cases in my opinion. By removing half of the data, there is bound to be issues.

    um, no dual layered games have issues. I have scrubbed versions of Brawl and metroid prime trilogy (the only 2 dual layers for wii), and neither have issues.
