The Last Guardian: unofficial PC port

An unofficial PC port of The Last Guardian (PS4: the US release CUSA03627 or the European release CUSA03745) for Windows. It is not rebuilt from the game's source code: it runs the game's own PS4 program, from your copy of the game's files, on a compatibility layer made for this game. The program's x86-64 code runs directly on your processor, without CPU emulation; the PS4 system libraries it calls are reimplemented for Windows (high-level emulation), and its graphics commands and shaders are translated to Vulkan. This project contains no game data, no game code and no keys, and it decrypts nothing.

• No CPU emulation: the game's own x86-64 code runs directly on your processor.
• Windowed, borderless or fullscreen, with a render resolution from 1280x720 to 3840x2160.
• 30 fps (the game's own limit), 60 fps or uncapped, at the game's normal speed: its timers count time, not frames.
• The languages your copy of the game carries: the US release's English, Spanish, French and Portuguese, or a European release's.
• Mouse camera with raw input; every keyboard and mouse control can be changed.
• DUALSHOCK 4, DualSense and Xbox controllers.

The PS4 has an x86-64 processor, like a PC, so the game's program can run on a PC processor. The port loads that program (eboot.bin and the libraries in its sce_module folder) from your files and links it to its own implementation of the PS4's system libraries: memory, threads, files, saves, sound (the game's NGS2 mixer with ATRAC9 and HE-VAG audio), movies, video output and controllers. While loading, it adjusts a few kinds of instructions: thread-local storage goes through Windows, and AMD's SSE4a instructions are emulated on processors that lack them.

The game drives the PS4's graphics chip directly, without a graphics API like DirectX. The port executes the game's graphics command stream with Vulkan and translates its shaders to SPIR-V as the game uses them, the same work a PS4 emulator does for graphics. A few patches to the game's code, applied as it loads and only to the exact 01.03 program, add features such as the raw mouse camera and the resolution setting.

Nothing from the game is in this repository.

• Windows 10 or 11, 64-bit, and a graphics card with a Vulkan 1.3 driver (NVIDIA, AMD or Intel) and about 4 GB of video memory.
• A recent processor with high single-core speed. Tested on a Ryzen 9 5900X with an RTX 4090: 30 fps everywhere, and with the 60 fps limit 60 in nearly every area, about 51-57 at the ending's start and 42-45 in the final battle; about 25-30 fps on a 6-core laptop CPU from 2019.
• Your own copy of The Last Guardian for PS4 (US release CUSA03627 or European release CUSA03745) at version 01.00 with update 01.03, as decrypted folders. The game folder holds 'eboot.bin', 'sce_module', 'sce_sys' and the 'trico_*.psarc' archives; the update folder holds the same for 01.03, or the update is merged into the game folder.
• About 25 GB of disk space for those files.

1. Download TLG-Port-<version>.zip from Releases.
2. Right click the zip, choose Extract All..., and pick a folder, for example 'C:\Games\TLG-Port'.
3. Start 'tlg-launcher.exe'. If Windows says "Windows protected your PC" (the launcher is not code-signed), click More info, then Run anyway.
4. On Game files, choose the game folder and the update folder. Leave the update folder empty if the update is merged into the game folder.
5. Click Play.

Unzip the new release over the old one or into a new folder, and start its 'tlg-launcher.exe'. There is nothing to set up again: your game folders, settings, key bindings and saves are in '%APPDATA%\TLG', which every version uses, and the shader caches in '%LOCALAPPDATA%\TLG' carry on too.

• Portable install (below): unzipped into a new folder beside the old one, the new version takes over the old one's settings, key bindings and saves at its first start (the old folder is left as it was).
• If your game folders are inside the old release's folder, keep that folder, or click Move here on Game files: they move into the new one's folder.

Delete the folder. Settings and saves are in '%APPDATA%\TLG', logs and caches in '%LOCALAPPDATA%\TLG'. If you moved your game folders into the port's folder (Move here on Game files), move them out first, or they are deleted with it.

Controllers work like the PS4 pad: Xbox and other XInput controllers, DUALSHOCK 4 and DualSense (USB or Bluetooth).

Keyboard and mouse (defaults):

In menus the left mouse button selects, the right one goes back and the wheel moves the selection. All controls can be changed in the launcher.

• Display mode, resolution, frame-rate limit, graphics card, volume and language are set in the launcher and apply the next time the game starts.
• Settings and saves are in '%APPDATA%\TLG'. Before each new save, the previous one is copied to 'save-backups' there (the newest 20).
• An empty file named 'portable.txt' next to 'tlg.exe' keeps everything in a 'user' folder beside it.

• At 60 fps the game's timers and effects keep their normal speed, but the game has not been played through at 60 fps yet.
• Uncapped is not recommended: at 116-119, 156-179 and 237-359 fps the game runs slower than real time.
• No mouse pointer in the game's menus.
• The title screen's music plays quieter than it should.
• Tested with NVIDIA graphics (a laptop and a desktop). AMD and Intel graphics have not been tested yet.
• The European release is tested with an English-only copy. Its other languages are offered when your game files carry them, but have not been tested. Japanese and the other Asian languages are in the game's program but need a copy that carries them.
• Now and then the game closes with an error just after an area starts loading (seen with the 60 fps limit and with none). Start it again and choose Continue: the game goes on from its last checkpoint.

Run tools\bootstrap.ps1 once. It downloads the pinned Rust and llvm-mingw toolchains into 'local\tools' and checks their SHA-256. Then tools\package.ps1 builds dist\TLG-Port-<version>.zip.
