Update! I'm currently trying to put together a set of tools to make hacking in general easier. This will include some existing tools (like CTPKTool as well as the existing DSC editors) as well as some custom tools to make editing the game's files easier. Currently, there's only one custom tool (made by /u/betasequence on Reddit) which extracts the contents of the spr_ae files and separates them into the individual CTPK files for easy modification. This tool uses Python 3.X Note: you still have to repack the textures manually into the original file, I might make a repacker when I have more Python experience.
