Ratchet & Clank: Going Commando

A matching decompilation of Ratchet & Clank: Going Commando for the PlayStation 2 (USA v1.01, SCUS_972.68): C that compiles to the game's own bytes, on the way to a native PC port.

No game files, disc images, rebuilt executables or proprietary tools are distributed: bring your own copy of the game.

Progress

Every distinct function counts once: the boot executable's 3,390 and the levels' 5,711 that the boot does not also have. A function many levels share is one function, however many places it has. A function is C when its C links into a program that comes out equal to the retail one (progress/report.json, tools/progress.py).

	Functions	Code
Boot executable	1,411 of 3,390	161,996 of 1,049,464 bytes
Levels	1,470 of 5,710	147,828 of 4,484,136 bytes
Total	2,881 of 9,100	309,824 of 5,533,600 bytes (5.60%)

The 27 levels hold 106,337 function placements; C covers 36,986 of them. 84 of the matched functions are the original's own assembly (ASM_FUNC), kept as assembly.

How it works

• tools/levels.py dump reads the boot executable and the 27 level programs from the disc.
• config/boot/functions.tsv and config/levels/functions.tsv list every function once, with its places (docs/LEVELS.md).
• src/ lists every function once, in address order, as its C or as an INCLUDE_ASM marker, as rac1-decomp does.
• tools/build.py all disassembles each program, links the C in place of its assembly, and compares every loaded byte with the retail program (docs/BUILDING.md).

Layout

Path	What
src/core/	the boot's core code (SDK, libc), one file per original object
src/game/	the boot's own program
src/levels/shared/, src/levels/NN_name/	level functions in several levels, and in one
nonmatching/	near misses, never linked
config/	the function catalogues, per-file compiler flags, naming research
tools/	disc reader and catalogue, build, progress, the compiler recipes
include/	shared headers
ports/pal-functional/	functional C for the PAL release (not matching)
docs/	building, the level format, the compiler, game research
