    Trim/Scrub ISO's

    Hey everyone, just curious about trimming my ISOs.

    I would actually like to keep the ISOs on my PC as well as my external WBFS HD. Using Wiiscrubber it looks like WBFS Manager essentially does the "Trim" command for you but I noticed something odd.

    When I just added the Super Paper Mario ISO (full disc size) to my WBFS drive it came out as 0.41GB. However when I trimmed my ISO on my PC using Wiiscrubber and then added it to my WBFS drive it came out as 0.40GB. The game still works as I tried it out.

    Am I safe to go ahead and trim the stored ISOs on my PC to save space and still have them work in USB Loader?

    from what I can tell Scrubbing just replaces the useless data with 0's and leaves the ISO the same size. Trimming organizes the data so its all sequential and the free space is all in one area instead of scattered throughout the disc so it can be chopped off reducing the size of your ISO.

    If the game worked,i'd say you're good to go.

    Ok I've played around with this a bit more. I recently tried out MLB Power Pros. Before I added it to my WBFS drive I trimmed it using WiiScrubber. When I tried playing the game I would just get a black screen so I removed the trimmed ISO and then added the full ISO to my WBFS drive and now it worked.

    The odd thing is that WiiScrubber cant even open an ISO that its trimmed (well it can but it gives tons of pop-ups and you cant see the partitions).

    Bottom line is that this method will not reduce the ISO size for you to store on your comp. I'm sure there must be a way... I just dont know what it is
