ekey / er.bdt.tool Goto Github PK

I have tried to use this following the instructing, but it did nothing. The command window flicked and gave no message, no error, no nothing. Is this method still working?

Expect BDT tool to unpack files into readable files, however the output folder created is called __Unknown and contains many files of differening sizes.

When Unpacking Data0.bdt with .\ER.Unpacker.exe "Z:\ELDEN RING\Game\Data0.bdt" "Z:\ELDEN RING\Game\Unpack" , it shows error below,

Uncatched Exception:  Org.BouncyCastle.Crypto.DataLengthException: input too large for RSA cipher.
    in Org.BouncyCastle.Crypto.Engines.RsaCoreEngine.ConvertInput(Byte[] inBuf, Int32 inOff, Int32 inLen)

    in ER.Unpacker.BinderUnpack.iDoIt(String m_BinderFile, String m_DstFolder)

How can I resolve it？

During my work on Binder Tool, I found all the file names for the current game version minus 12 weird ones that seem like near-identical duplicates of the data0 shader files. My fork is here. The file names are in /BinderTool/DictionaryER.csv, but they're stored with the alias roots the game uses (e.g. "map:/"). You can use a simple search-replace in a text editor or something or use the FileNameDictionary.MakeHashable function in Binder Tool - FileNameDictionary has a list of all the aliases used in DictionaryER as well as what they should be replaced with.

regulation.bin is the regulation file for Elden Ring. Data0.bdt is a data file now, unlike previous DS3 etc.

I found a lot of parameters from the regulation file, just like other from software games.

Hi @Ekey,

When I run the tool, I get the following exception:

Any ideas how to fix it?

Thanks a lot for the tool.

Hello!
I'm getting this error despite having copy-pasted oo2core_6_win64.dll in the unpacker folder, am I missing something?

Most of them are BND file, except 92FB1CEB78F552AD which is a PSC file.

I can unpack all BND files using BinderTool. The unpacked files contain lots of .ppo and .vpo files. It seems that they are shader and texture.

Hi, Sir, nice tool! However, don't know how to use it. In visual studio? or directly in cmd (apparently not)? dotnet build doesn't work neither.

Looking forward to your response!

Hi ! im new to modding Fromsoft games. The readme file does not have any instructions. would love to know how to use this
