Gran Turismo 6,
statically recompiled.

The PS3 version of Gran Turismo 6 (BCUS98296) translated ahead of time into C++ and built as a native x86-64 Windows executable. A true native port in progress.

Current gate: resume the real manager's state-2 boot-project continuation, then observe K/IE / K/WD. The genuine frame is still the black cover.

Where it stands

Boots and presents a 1280×720 window
Full ADCH boot script parsed — 857 KB, 255k reads to EOF
UI packages and menu scripts load — MenuClassDefine, cursor.*, arcade/option/gtmode/garage/gtauto
Font / file-worker gate passed — generation-based lwcond + synchronous host-font reads
MGOM.start fires and sets the boot-project request
D3D12 present path reaches the screen — flips and clears land
First visible frame still in progress — manager remains at state 2; K/IE and K/WD are not yet observed
Far from playable

The RPCS3 oracle confirms the v1.00 disc alone reaches the legal / loading screen, first-run UI and intro. Prototypes.adc is a native loader artifact, not a missing game file.

What this is

An experimental static recompilation of the PlayStation 3 version of Gran Turismo 6 (BCUS98296). The game’s PPU code is translated ahead of time into C++ and built as a regular Windows executable.

This is not an emulator. There is no runtime interpretation of PS3 instructions. The long-term goal is a true native port.

The project ships code and documentation only. No game assets or copyrighted material are included — you must supply your own legally obtained disc files.

What works

GT.VOL: 4,207 TOC entries, 32,591 files
Boot script: Full ADCH012 parse, 255,264 reads
PPU lift: 75,652 functions
SPU / SPURS: 15 job images, dispatch rc=0
HLE / threads: 1,216 NID handlers
Present / clears: Flips reach D3D12
UI scripts: MenuClassDefine, cursor.*
PFS cache: Boot/presents + fonts seeded
Frame capture: Backbuffer BMP + verifier
Intro (offline): 136 s 1080p H.264/AAC

Next up

01Resume the state-2 menu project continuation through the original callback/update path without forcing cleanup.
02Observe K/IE / K/WD, bind a real GPB texture, and render the first non-black legal frame with GT6_BRINGUP_DDS=0.
03Then menus, audio and input; in-engine PAMF playback is a separate clean-room HLE task.

Contribute

Still very early. Experience with PS3 reverse engineering, static recompilation, D3D12, or the GT engine is useful. Issues and discussion are open on the repository.
