[Release] Source - C9U Text String Decompiler/Compiler

[fallenfate]

Hi all,

Spent an hour digging and found this for us all. It seems to only convert text strings from C9U files, but it's start, no?

Attached is a compile and below is the source. Credits to Brouznouf.

Instructions

1) Download and place this .exe in a folder - View attachment c9udecode.zip.
2) This is a console app, so it runs via command line only.
3) Place any C9U file you want in the same folder as c9udecode.exe
4) Run the .exe like this:

c9udecode.exe 0 filenamehere

0 = Decode, 1 = Encode

NOTE: When encoding, you need to have the _translate_file.txt document for the file in that same location as well as the .new.c9u file.

When you will stop release a per day? xD Nice tool it's useful thanks mate

 

[Oraclebr]

 

[NaiWan]

Always crash, But thank you.

 

[fallenfate]

Always crash, But thank you.

It crashes when you compile, or the compile crashes? Works fine for me, keep in mind the usage directions.

 

[NaiWan]

It crashes when you compile, or the compile crashes? Works fine for me, keep in mind the usage directions.

I'm trying to run .exe with command

 

[fallenfate]

@NaiWan Strange, and the .c9u file is in the same folder as the .exe? :/

 

[WireShark]

I'm trying to run .exe with command

always run as administrator your cmd and then go to the path where your decoder and files

example: cd c:\c9udecoder\c9udecode.exe 0 c:\c9udecoder\filenamehere hope that helps
also dont forget

NOTE: When encoding, you need to have the _translate_file.txt document for the file in that same location as well as the .new.c9u file.

 

[NaiWan]

Tried, but still error

 

[WireShark]

Give me the file you try to encode and ill try on mine

 

[CrazyGuardian]

Help Please

 

[hemaprince]

@fallenfate please attach a translated c9u to english if possible

 

[xlmansox]

How to use : start c9udecode.exe 0 filename

save as bat file.

 

[fallenfate]

@fallenfate please attach a translated c9u to english if possible

Any particular c9u? As long as it isn't like 10000 lines long, I have time to translate one file for you, sure . Unfortunately I cannot test anything massive, not yet. My main PC is having issues but I have tools on my laptop, it just won't run things well enough without me ripping hair out, and I'm running out of it already.

@Stunn Sorry for the delay, will try to test what you PMed this week.

 

[Stunn]

@fallenfate ok, if it gives any error, just use CHSFILEMANAGER, to update c9cfsinfo.dat to the folders that were changed.
