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.
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).
The report also gives the boot executable's data (383,391 bytes of initialised data, for the Data bar on ByteMatch). None of it is matched yet: the build places C functions' code and discards their objects' data, so all of it still comes from retail's dumps. The levels' data is not measured.
| Functions | Code | |
|---|---|---|
| Boot executable | 1,470 of 3,390 | 170,200 of 1,049,464 bytes |
| Levels | 1,471 of 5,710 | 147,888 of 4,484,136 bytes |
| Total | 2,941 of 9,100 | 318,088 of 5,533,600 bytes (5.75%) |
The 27 levels hold 106,337 function placements; C covers 38,445 of them.
84 of the matched functions are the original's own assembly (ASM_FUNC), kept as assembly.
tools/levels.py dumpreads the boot executable and the 27 level programs from the disc.config/boot/functions.tsvandconfig/levels/functions.tsvlist every function once, with its places (docs/LEVELS.md).src/lists every function once, in address order, as its C or as anINCLUDE_ASMmarker, as rac1-decomp does.tools/build.py alldisassembles each program, links the C in place of its assembly, and compares every loaded byte with the retail program (docs/BUILDING.md).
