xex_fragment_finder is a command line tool created by Bo98 to find fragments of XEX files inside a disk image. At this time, it only supports XEX2 executables using both encryption and compression. Support for unencrypted or uncompressed files may be added at a later date.
This is not an easy program for beginners. You will likely need experience with hex, some knowledge of the FATX filesystem, and a little knowledge of XEX files.
Note the help page below. Anything listed as REQUIRED must be defined in your command; however, you will most likely also need to define
image-offset-end. Since this tool is only intended for searching along cluster boundaries, you must define these values as a multiple of 0x4000 away from the fragment start. This means if your XEX start offset ends in 0x5000, your image start/end offsets should end in 0x1000, 0x5000, 0x9000, or 0xD000.
fragment-sizewill also likely need to be defined, but unless you know there's only one fragment and have the exact size of that fragment, it should be left as the default to start with.
Attempts to find lost XEX fragments. Usage: xex_fragment_finder [OPTION...] -i, --image arg REQUIRED: Input image file to scan and extract from. -f, --xex arg REQUIRED: Input XEX to find the fragment of. -o, --output arg REQUIRED: The output directory to place possibly valid XEX files from found fragments. !!!THIS DIRECTORY WILL BE WIPED!!! -x, --xex-fragment-offset arg REQUIRED: The offset of where the fragment would go in the XEX. If there are multiple to find, pick the first. -k, --key arg REQUIRED: The key to use for decryption. Pick from: "dev" or "retail" --image-offset-start arg The offset to start scanning the image from. (default: 0) --image-offset-end arg The offset to scan up to in the image. (default: 18446744073709551615) --fragment-size arg The size of the fragment to find. (default: 16384) --threads arg The number of threads to use. (default: 16) --help Print help.
