mgsv_path_hasher

Creates a filename hash used in fmdl/fv2 files in MGSVTPP (probably .dat files too). See http://forum.xentax.com/viewtopic.php?p=121141#p121141 for more details on fmdl/fv2.

Put filenames you want to hash into 'input.txt', grab hashes from 'output.txt'.

Options

• '/r': re-reverse hashes;
• '/p': print hashes to console;
• '/h': supress any messages.

Hashes

Hashes are reversed by default so you can just copypaste the output and search for it using your favorite hex editor. Hashes are also truncated to last 12 bytes out of 16 - sometimes first 3 bytes differ. Small hashes are padded with zeroes from left ie hash 12345 becomes 000000012345 - I am not sure is this the right way.

Path length

Game doesn't recognize long filenames (or filenames with dot in filepath).

Example:

-	-	-
Hex representation in fova		5b ee d2 04 a5 a0 a2 84
Full filepath	/Assets/tpp/item/ewr/Scenes/gog1_main0_def	84 a2 a0 a5 04 d2 ee 5b
Trunkated filepath	tpp/item/ewr/Scenes/gog1_main0_def	2 a0 a5 04 d2 ee 5b

Based on atvaark's tool. https://dotnetfiddle.net/3RBp5V - online version without reversability.

Compiling

1. You will need .NET 4 and CityHash.dll - https://www.nuget.org/packages/CityHash.Net.Legacy/.
2. Put CityHash.dll along with main.cs.
3. Execute C:\Windows\Microsoft.NET\Framework\v4.0.30319\csc.exe /r:CityHash.dll main.cs
4. Done.
