compression question

[dparr59]

Now that i have my SH-D162c Kreon Flashed drive, I have one question. I don't want to ruin the existing read dumps I have of three games sitting on my PC. I have burned them and they work fine in the Xbox360. I just have one question. I have heard that several people have a hard time when they make copies of copies. I am just wondering (for storage of images purposes) is it possible to zip or compress the images so that they can stay on the computer as a backup file. I know I can zip them by running winzip, what I am wondering is how much space would that really save on a 8G file of this type and would unzipping it cause any damage to the file so that it wouldn't work any longer when burned. Just curious if anyone else has thought of this? I haven't seen any posts searching on the forums.... It is mainly a time saver if a copy disc gets scratched beyond readability and it would be much quicker to burn a new one from an existing image instead of dumping a read of the image and then burning it again. In case anyone thinks I am talking about stealing games from Blockbuster and having to re-rent them, I am not, I am talking about games I own solely.

Thanks,

Jeff

At this time, it is not possible. The game files themselves are normally much smaller than the normal raw images. Whereas the normal rip is always over 7gb in size, the actual game content may be 5gb (varies on the game). It's basically 2gb of dummy data .. but it is necessary. At the current time, all of the security placeholders (aka that dummy data) is necessary. It contains certain information which is required for the image to boot and run correctly. People are currently working on possible methods of removing the security placeholders or at least the ability to remove them, then replace them later on.

Both are not possible at the moment. Of course, you can still use conventional archiving utilities like WinZIP, RAR, 7-zip, etc... but I don't think you'll be saving much space.

So as of now, there's not much you can do in terms of image compression.
