Title Update hash mismatch

[Pollot]

Validation

• I have checked the Issues page to see if my problem has already been reported
• I have confirmed that this bug does not occur in the original game running on original Xbox 360 hardware

Describe the Bug

The installation process fails because the hash of default.xexp from the Title Update I am using is not present in the list of known hashes. As a result, the installer cannot proceed.

Expected Behavior

The installer should recognize default.xexp as valid and proceed with the installation, considering that this Title Update works correctly with all DLCs on Xbox 360 hardware and the Xenia emulator.

Additional Context

The Title Update in question was extracted from my Xbox 360 (I own the GoD version of the game). It is labeled as Title Update #1 (instead of #2), but it functions correctly with all DLCs on both Xbox 360 and Xenia. The contents of the work folder are identical to other Title Updates, suggesting that this may be a regional difference.

I calculated an XXH3 hash for my file, but its format differs from the hashes listed in the repository. Therefore, I was unable to build a version with this hash added.

We may just need to add this to the list of known hashes.

Can you build the tool available at https://github.com/hedge-dev/UnleashedRecomp/tree/main/tools/fshasher, which is responsible for creating the hashes of the known update versions? I imagine you must've dumped this from some source I do not have access to. Is it perhaps the EU GoD version?

If you can run fshasher on these files, we can add them to the known hash database so it accepts it.

For further reference, this is the file we'd have to merge in the hashes from the update to: https://github.com/hedge-dev/UnleashedRecomp/blob/main/UnleashedRecomp/install/hashes/update.cpp

It is indeed the EU GoD version. I will build this tool and try adding the hash to the array of known hashes.
