PS2 Iso Hacking

[rednekcowboy]

Ultraiso does not save TOC/LBA data properly.

I used S**Y's CDVDGEN or Apache3 to rebulid the iso image.

I would just edit the system.cnf file points to uLe and create new folder holds uLe and CB

K, I get what you are saying, but how do I find out the LBA data? I can use CDVDGEN but I'm not sure how to code the LBA data or where to even start....

Just as an aside, Ultraiso must do a heck of a lot better job than I was doing with cdvdgen because I now get it to boot whereas with the generator, it was not. EDIT: I realize that may have sounded like I was being a smart-a$$, that was not my intention in the least and I'm sorry if it came across that way....

Quick question about LBA. If I open up the iso with Isobuster, it shows an LBA column. Do I just open the iso with a hex editor, go to that line, copy the string and then insert it in the new iso I've created?

I've actually got both methods that I've listed here booting up, can select and boot codebreaker, but when I go to boot the game, I just get black screen with and without loading codebreaker first so I'm assuming, it's like Lee said. I need to ensure that the lba is correcct in order for it to be bootable just don't know how to do that.

When you insert new files, larger files, or otherwise move things around in the image, the table of contents needs to be updated to reflect the new location on disc. That's it. If you use a tool that can rebuild the image, it should update the TOC for you. Lee4 suggested some tools you can use. If you know where to find the contents listing, yes, you can update it manually with a hex editor. But why waste that time?

I'm reasonably certain PS2 games typically seek using the TOC, as opposed to the situation on the PSX where you'd often find LBA listings compiled into files, so it could seek directly by address. So if you have the TOC updated, you at least shouldn't have seek issues.
