    Heya,
    I was just going through my games and noticed somewhere (forgot where) people are trimming the size of cso's down even more by deleting the update folder, is that safe to do? Im using UMDGEN 4.00 so I know how to do it I just want to make sure it wont screw anything up. Are there any other files I can remove but keep the game fully working?

    Cheers

    (No it shouldnt be in help its just a quick questions =P)

    Update folder is fine to remove. There won't be any side effects what so ever; besides loosing an update of course.

    Another thing that can be ripped from ISOs and don't effect game play at all is padding. Padding is only used for when you have the UMD. It can be ripped safely. Also, padding is only found in some games...not all.

    You can also rip music/sounds and movies. Yet, if you take those away, you'll obviously loose something from the game.

    There's a tutorial in the tut section. It has a lot more info.


    Edit: Look at my post count :twisted:

    You can also delete the boot.bin file...it usually isn't very big, but...

    Actually, you can delete the eboot.bin OR the boot.bin, just not both...

    Here's the great guide to shrinking your ISOs.
    http://www.psp-hacks.com/forums/viewtopic.php?id=15071

    Read it.

    Update and pad files do not have to be dummied...I believe. I think you can just delete them. Read the guide to be sure. :|


    Dammit...my post count isn't 666 nomore :mad:

    I've tested almost 100 ISOs and deleting the boot.bin has not caused a single problem with any of them...

    The psp-hacks guide is very good, but misses this point entirely...

    Not true for all isos.


    Deleting the update folder will render certain ISOs useless due to LBA Protection.

    You would have to export LBA addresses first, delete the update lines from the text file, dummy the update folder, and then import the LBA addresses to force the files to use the new LBA positions.

    If you delete the update folder from a particular ISO and find that your ISO doesn't load, then the game has LBA protection.

    True, but generally, UMDGEN will give you an error when recreating the ISO when this is the case...at least I've seen it with version 4.0...

    Ahhh yes. I've forgotten about LBA Protection. Mainly because I never had to deal with it. :lol:
    I believe Bleach is one of the games with LBA. Not sure which one. :|

    I guess, follow the guide and tread carefully. Be aware of which games have LBA and which don't. Google.
    Use Rip kits if necessary....UMDgen....etc..etc..:mrgreenthumbsup:
