As previously mentioned, AtlusScriptCompiler can decompile .BF
and .BMD
into .FLOW
and .MSG
respectively. This allows us to view scripts in plain text and edit to our liking.
First, you must tell the program what file we're working with.
For decompiling, this must be a .BF
or .BMD
file.
You can simply drag AtlusScriptCompiler.exe
and then input.bmd
onto the command prompt window.
This will automatically wrap each paths in quotes, which keeps arguments separate in case your paths contain spaces.
Now, let's tell the program what to do with that file.
Add -Decompile
, separated by a space.
A Flowscript Library instructs the compiler on function names and parameters.
In order to work with the input file, you have to tell the compiler which Library to use with -Library
.
Not all games have libraries available. Knowledge of reverse engineering game executables is required to generate a library, as you'll have to find the offsets of function signatures yourself. A sample script for dumping that data from P3/P4 (PS2) can be seen here.
An Encoding can be specified using -Encoding
.
It lets the compiler know what set of characters to use.
Finally, you can name the Output File using -Out
.
If -Out
is not specified, it will default to the input filename and folder, but with the output filetype appended. In this case, that would be C:\Path\To\input.bmd.msg
.
At this point, you can press Enter
to begin decompiling.
