This repository contains the scripts I wrote in the few days I spent reversing the Frozen Synapse game. They are released in the hope that someone wanting to write mods for the game will find them useful, but as for me, I've seen enough about its internals and don't plan on digging further.
I realize that these scripts could be used to enable cheating in multiplayer modes, so all I can say is: don't be that guy.
All the code is released under the terms of the GPLv3 license.
The python files were made using Python 2.7
This script is a quick client implementation which enables you to log into the game's server and get information from the lobby. You can also use it to download encounter files, which describe games.

* Server ping *
To use it, modify line 67 (if not login(s, "[username]", "[password]"):) with your own username and password. uncomment s.send("textcom\tcommand\tselectMT\t[game ID]\n") to obtain turn files for a given game.
Read through the script to find more commands to communicate with the server. You are also encouraged to use Wireshark and snoop on the game's traffic if you want to extend the client's capabilities.
An incomplete parser for MT (multiturn) files, which describe a Frozen Synapse match.
Only the file's header is parsed; the rest of the format hasn't been reversed yet (although the script contains some pointers). I may go back to it one day. If you want to do it, you should look at the Encounter::saveTo(Encounter *this, const char *) function with IDA.
$> ./frozen_parse_mt.py enc/caff_finished.enc
Game 1321834 (finished with a score of -40.00 in 4 turns)
Player 1: caffinator (Rank: 4276 - Level: 18 - Wins: 52 - Losses: 62)
Player 2: SniperZwolf (Rank: 188 - Level: 129 - Wins: 610 - Losses: 248)
Match history: caffinator won 0 time(s) and SniperZwolf won 1 time(s).
This is a decompiler for DSO files. It is compatible with the latest version of the Torque engine, and also the old one used by Frozen Synapse. The code it generates can most of the time be used to replace the original DSO files which is quite nice, but it is far from being 100% foolproof. You may have to manually correct syntax errors if the game stops working as intended. Worst case scenario, you should still be able to read the game's code. If you're working on an interesting mod and face some issues with the decompiler, get in touch with me and I'll do my best to fix the problem!
You can probably use this script to decompile other Torque engine games, but depending on their version, some modifications may be necessary. At some point between version 36 and 44, an offset was introduced in the opcodes. If you encounter problems, your best bet is to modify the translate_opcode function in torque_vm_values.py so opcodes are translated for the version you are working on. Again, feel free to get in touch with me if you need a hand here.
