Scrapland Reverse Engineering notes and tools

Scripts:

• parse_save.py: Dumps information extracted from Save file
• scrapper.py: Extractor and Repacker for *.packed files, needs the construct and tqdm python modules and python 3.x

• Run scrapper.py -h for help

• r2_analyze.py: uses radare2 to parse and label a lot of interesting stuff in the Scrap.exe binary
• lib/dbg.py: general Script for poking around inside the game's scripting system

• Run import dbg inside the Game's Console, this will load all builtin modules and enable godmode
• The dbg module also enables writing to the ingame console using print <var> and defines two global functions s_write() and e_write() for writing to the Ingame Console's Stdout and Stderr Stream
• dbg.menu() Displays the Game's built in Debug Menu (doesn't work properly)
• dbg.enable_all_conv() allows you to "overwrite" any character, even if they are protected/invulnerable
• dbg.become(name) allows you to transform into any character
• dbg.helplib() generates a file helplib.txt in the Game's folder containing all available Documentation for all available classes and functions
• dbg.settrace() Logs all Python function calls together with their arguments into a dbg.txt file inside the Game's folder
