    Hi I just want to ask how to combine 2 Disc ISO into 1 Iso , because I downloaded the The Legend of Heroes : Trails in the Sky Second Chapter and it comes in two iso, I want to combine it and make it into one ISO.

    As in they're two separate ISOs and not one split into two files? If they are just separate ISOs, I can't think of any way to safely merge them and it work. Theoretically, with a lot of work you could build an eboot out of them, but that would be an insane amount of work for a minor convenience, and I wouldn't even know where you would start.

    If they're just a split ISO, you should be able to run something like:
    Code:
    cat Part1.iso Part2.iso > Complete.iso
    
    Well, using a linux distro with a terminal. Not sure about under Windows.

    Hehehe... yes its two ISO Disc 1 and Disc 2, with 1.3gb Disc 1 and 1.2gb Disc 2, I think i'm just gonna go and play it in two disc, if combining it will take to much time and searching for solution take so much time also, : ) thanks for the reply.

    it's not easy to merge two discs into one.
    first you need to extract both, then compare the folders and files (filename could be the same but with different content!, different menus or data based on disc or story progress)
    then merge all folders.
    But that's not all, the game need to know that it can read the files without switching discs, so you need to edit the file table, and hack the executables to read files instead of asking disc swap, etc.

    extract and rebuild ISO is the easier part.
    editing and hacking the game is hard
    There's also a size limit (2GB?) for ISO, not all CFW are compatible with big single ISO.

    If size is the concern, run them through UMDGen. It has an option to optimize and shrink padding. So you'll be left with mostly just the game, little to no garbage data they put in to push to the data to the outside of the disc.
