SFormats is a collection of Python scripts using the Construct declarative data parsing library to define a few different file formats I've worked with and had to parse over the years.

Each structure file has a brief description of its purpose in the header.

At one point I was attempting to write a Flash (ActionScript 3) decompiler. I never quite got it working, but I did manage to parse SWF files, ActionScript code blocks, and AS3 bytecode instructions.

I've done a lot of work relating to Hamumu games, and in the process of this work had to parse graphics, world data, and save and profile data.
