    Hey,

    Do any of the WAD managers out there support installing WADs inside of a zip file? I keep my WADs compressed on a USB drive, and it would be nice to be able to install them in one step rather then unzipping them and then installing. Thanks.

    Don't know of any WAD managers that support ZIP archives, but you can use WiiXplorer to unzip the WADs temporarily and then use any WAD manager to install them. This will allow you to not have to use a PC as part of the process at least.

    Like PPSainity said, no WM supports zip archives. Use WiiXplorer to extract them if you don't want to use a PC.

    My question is: why are you keeping them zipped anyway? Wad files don't even compress. You'd be lucky to save a few hundred kilobytes.

    To ensure the wads do not become corrupt. They should always be zipped or rared, md5 is good to.

    That's understandable for downloads...they won't extract if they're incomplete or damaged.

    But is it really needed once the file is on the SD card? Not only is it unlikely that the file would go corrupt for no reason (granted it DOES sometimes happen), the wads also have features (e.g. content hashes) designed to help prevent bricks from corruption.

    Last time I tried to install a hosed wad, the WM spit out an error because the hashes didn't match.

    it would be nice to see a wad manager with zip support. kind of annoying having to extract a zip each time you want to install a wad.

    There is no point in keeping them zipped, that's why. WAD is already a compressed archive format.
    Lazyness does not have limits apparently :-)

    If you are using Offline List to rename your wads, it's automatically zipped. [​IMG]

    Actually, WAD is not compressed at all, just encrypted. Some content inside might be compressed (LZ77 and ASH are common), but a lot of it often isn't.

    If you unpack a title and zip the resulting folder of content, some titles compress quite well, and even better compression can be obtained with effort.

    If someone made a WM that can install titles from a zip archive containing unpacked wad components (i.e. archive with a ticket, tmd, cert, and .app files inside), there could be a point to this. The zip could provide compression, convenience (no extracting), and brick protection (a CRC check on top of the TMD's SHA1 content hashes).
