Atlus Script Tools

WIP set of tools developed for handling Atlus' script formats including

• flow script files (.bf)
• message script files (.bmd)

All of the code is written in C# and licensed under the GNU GPL.

Latest build:

• https://ci.appveyor.com/project/tge-was-taken/atlus-script-tools/build/artifacts

Overview of repository structure

Source

• This is the source code directory of the project. This is where the main solution and its projects are.

AtlusScriptLibrary

• This is the main class library of the project. All of the core functionality will be implemented here, with the other programs serving as a front-end.

AtlusScriptCompiler

• The commandline frontend for the script compiler. This application is used for
  • Compiling & decompiling flow scripts from/to the uncompiled format (.flow) or from/to compiled format (.bf)
  • Compiling & decompiling flow bytecode code from/to the uncompiled format (.asm) or from/to the compiled format (.bf)
  • Compiling & decompiling message scripts from/to the uncompiled format (.msg) or from/to the compiled format (.bmd)
  • Compiling & decompiling message bytecode from/to the uncompiled format (.asm) or from/to the compiled format (.bmd)

AtlusScriptEvaluator

• This application is used for
  • Evaluating compiled or uncompiled flow scripts (.bf & .flow) and providing statistics
  • Evaluating compiled or uncompiled message scripts (.bf & .flow) and providing statistics

Utilities

• This is where misc utility programs using the library will be stored. Also serves as a reference for anyone wanting to use the library.

AtlusMessageScriptExtractor

• This application is can batch extract the text from message scripts from within various binary files. Use this is if you want a quick dump of the text from a game.

AtlusFlowScriptExtractor

• Similar to the previous program, it can batch extract scripts from within various binary files. Use this is if you want a quick reference of all the scripts used in a game.

AtlusFlowScriptInterpreter

• WIP interpreter for flow scripts. Not suitable for use yet.

packages

• Nuget packages.

Documents

• This directory contains all kinds of documents to serve as documentation for the file formats, and other things such as reversed engineered game code.

Scripts

• This is where any misc. scripts will be stored, for the sake of keeping everything safe from being lost. ¯_(ツ)_/¯

Build

• Not visible on the repo but this is where all of the binaries will compile to.

What's finished?

Finished

• Reading and writing of flow & message script files.
• Simplified representation of both flow & message script files.

Somewhere inbetween

• Decompilation and compilation of message scripts. They're both missing an implementation of function aliases, but besides that they work.
• Compilation of flow scripts. The compiler is currently able to compile some decently complex scripts, but some things still need to be worked on.

Unfinished

• AtlusScriptEvaluator
  • Evaluating compiled or uncompiled flow scripts (.bf & .flow) and providing statistics such as syntax errors or stack over or underflows.
  • Evaluating compiled or uncompiled message scripts (.bmd & .msg) and providing statistics. Not sure what kind of statistics would really work here though.
