decomp-toolkit-scripts

Scripts for setting up and using a matching-decompilation toolkit on Debian/Ubuntu. Contains no game code.

File	Purpose
install-debian.sh	Installs JDK 21, Ghidra (SHA-256 verified), radare2, MIPS/PPC cross gcc+binutils, clang, a Python venv (splat64[mips], capstone, lief, pyelftools), m2c, asm-differ, decomp-permuter, jadx, ilspycmd
env.sh	source env.sh to set JAVA_HOME/GHIDRA_HOME/PATH and aliases (m2c, asmdiff, permuter). Root via DECOMP_TOOLS (default ~/tools)
decompile.sh	Ghidra headless: ./decompile.sh prog.o [func ...] prints C
ghidra/DecompileAll.java	Headless script used by decompile.sh; ghidra/Decomp.java is the minimal original example
match-check.sh	./match-check.sh guess.c target.o mips-linux-gnu-gcc -O2 → MATCH or a disassembly diff
