What was done
ReGTA CTW is an independent reverse-engineering project aiming to port the European PSP version of Grand Theft Auto: Chinatown Wars to native Rust for Windows x64. The project is currently in pre-alpha, focusing on system implementation and PSP behavior validation.
ReGTA CTW is an independent reverse-engineering and native-port project for Grand Theft Auto: Chinatown Wars, specifically targeting the European PSP release (ULES-01347, version 1.01). The project aims to rebuild the game experience in Rust for Windows x64 without using a PSP CPU emulator. Current implementations include player movement, camera profiles, vehicle systems, and combat mechanics. As of October 2026, the project reports 184/184 passing unit tests and 166 indexed code overlays. The developer notes that these metrics represent progress measurements rather than full-game equivalence. The project documentation explicitly states that it is in a pre-alpha state with no public playable download available. AI models are utilized within the project's governance and documentation workflows, with commits documenting the enforcement of status updates across AI models. The project maintains a strict policy of not including proprietary game assets, requiring users to provide their own legally obtained ISO for local validation.
Reproduce it
Requirements: Windows x64, Rust toolchain (validated with 1.90.0), and a personal ISO of ULES-01347 v1.01. Run '.\Compiler.ps1 -Test' to validate the build, then execute '.\outputs\CTW-Rust\CTW-Rust.exe --iso "D:\Games\Chinatown-Wars-PSP.iso" --slice'.
