ScrapHacks

History

Daniel Seiller 7afdfb5869 Lots of changes, expand to read - Add notes folder with MDBook documentation (the NOTES.md file was getting kind of large) - Add rz_analyze.py, does the same a r2_analyze.py just with Rizin instead of radare2 so the project can be loaded in Cutter (and it's faster) - Add Scrap.rzdb, Rizin database for the Scrap.exe executable - Add Scrapper_rs, Rust version of .packed extractor and repacker - replace helplib.txt with helplib.md - add Py_Docs folder which contains generated documentation for the binary python modules built into Scrap.exe		2021-01-20 23:53:14 +01:00

Features

read and write memory
disassemble memory (using zydis)
change DirectX state
Draw DirectX overlay (still need to make a useful overlay)
Dump various data structures to the console
Assemble and execute code on the fly (using asmtk)
Can be controlled via keyboard shortcuts (TODO: allow defining own shortcuts for commands)

Prerequisites

Visual Studio 2017/2019 (others might work)
CMake
Python 3.6 or newer

Building

Open VS 32-bit command prompt (vcvars32.bat) and run the following two commands

cmake -G"NMake Makefiles" -B build
cmake --build build --target install

This will find the Games's installation folder, verify that the version you have is compatible with ScrapHacks and drop the compiled .pyd file into the correct folder to be imported

Getting started

open the ingame console (Ctrl+^)
type import ScrapHack
type $help
