Current Steam binary seems to not match any SHAs of known NA binaries

[Wesmania]

The binary I downloaded in my Steam has this sha256sum:

042e9fef839eb1c7722cee971d5f50c132b018ec02aa0d4ae38dbc62d5a9daa8  NieRAutomata.exe

This does not match any sums in Utils.h. Moreover, I can't seem to find at least one of the patterns in FindSteamOffsets, for g_pGraphics. I opened the binary in Cutter and didn't find 48 85 db 0f 84 anywhere in the exe. Same goes for patterns in FindDenuvoSteamOffsets.

This is very confusing since steamdb claims that the binary has not changed in 2 years. I am on Linux, but the game runs via Proton so I'd expect the executable to be the same as in Windows. I have no idea where the issue lies, but maybe this report will be useful.

Also a note on symptoms:

• At first the game crashes in bcrypt functions, that's because Proton has them stubbed out and always dereferences the handle as a pointer. After rebuilding the dll with the hash check removed, the crash happens near the end of FindSteamOffsets. Presumably because g_pGraphics search returns nullptr, which is then dereferenced.

Even weirder: downloading a depot manually via Steam console gives me a binary with a known SHA256:

download_depot 524220 524221 4633942970953135000

5171bed09e6fec7b21bf0ea479dbd2e1b228695c67d1f0b478549a9be2f5726a  NieRAutomata.exe

It's indeed not the issue with 2BHook then, but still weird.

Steam is replacing the binary on startup. Odd.

Doing chown root:root and chmod -w is a workaround, and the dll does load without crashing.

nvm i actually do have a definition for the steam packed w/ steam drm. So it crashes if it doesn't know the sha? Actually that makes a bit of sense cause the offsets & sigs might change.

Crashing is linux-specific behaviour, Proton doesn't support windows bcrypt API fully and always tries to dereference one of the arguments that can be either a pointer or a special constant. It only crashes later because I removed the check altogether. I assume on Windows it just doesn't load further if the sha check fails.

If you mean my SHA256 thing i still let you load it all that changes is it would say NieR:Automata (Unknown Version) in the debug console but if a critical sig isn't found it would probably crash for that i just warn %s is null! This may have fatal consequences! I have never ran this on linux tbh.
