THPS2 Demo Decompilation

Source-only work-in-progress reconstruction of the PlayStation THPS2 demo.

This minimal public snapshot contains the recovered C/C++ under src/ and the scripts needed to compile-check every translation unit. It is an unofficial research project and is not affiliated with or endorsed by Tony Hawk, Neversoft, Activision, Sony, or any other rights holder.

Not included

This repository intentionally excludes:

• the original executable, game assets, MAIN.SYM, and MAIN_STRUCTS.h;
• Psy-Q SDK files, ASPSX, PSYLINK, and other Sony software;
• downloaded compiler or assembler binaries;
• target disassembly, generated objects, link products, and matcher caches;
• recovered or leaked original source and development-project files; and
• private work logs, experiments, IDE state, and local paths.

Use only external inputs that you are legally authorized to possess.

Compile check

The supported environment is Linux or WSL with Bash, Python 3, GNU cpp, wget, and tar. Supply your licensed Psy-Q 4.6 (DTL-S2360) SDK headers at:

toolchain/psyq-4.6-sdk/INCLUDE/

Then run:

bash setup_toolchain.sh
bash build.sh

setup_toolchain.sh validates the user-supplied SDK headers and downloads the separately distributed GCC compiler. It does not download Sony software or game files.

build.sh compiles all recovered translation units as a source-integrity check. It does not link a game executable or perform binary matching; those workflows require proprietary and target-derived inputs that are deliberately outside this repository.

Evidence and rights

The reconstruction is based on permitted binary/debug evidence and reproducible compiler experiments. Unlicensed original source, editor/tag databases, and development-project files are not accepted as evidence.

This repository has no blanket open-source license. See LICENSE_SCOPE.md for the copyright and third-party-rights scope.
