Silent HillPC Port

The game itself is not AI-generated. This port is built on the Silent Hill decompilation — the original game's actual code, recovered function by function from the PlayStation release — and that code runs essentially untouched.

The PC-specific work lives in a separate layer, fenced off behind #ifdef SH_PC_PORT blocks and a small pc_port module, on top of PsyCross: an open-source compatibility layer that emulates the PlayStation's hardware (GPU, SPU audio, controllers and so on) so PSX code can run on a modern PC. PsyCross has been modified and extended to fit this game's needs.

AI assistance was used to write and debug that porting layer — the 64-bit fixes, the hardware shims, the bug hunts — not to rewrite or invent the game. The core Silent Hill you're playing is the same game: same logic, same data. Mostly. There are certain parts of the code where the port bypasses the game code and uses its own. These are simply placeholders until the real thing is working, and many are already fixed.

Hand-porting a decompiled PlayStation game to PC is an enormous amount of work — thousands of low-level fixes spanning rendering, audio, memory layout, 64-bit pointer math and hardware emulation. Done solo and by hand, that's the kind of effort that takes years of spare time and a deep, specialized skill set.

AI lets one person move at that pace. It doesn't replace the human, though: I (KushAstronaut) drive every decision, test the game constantly, recognize when something is wrong against the real PSX behavior, and steer the AI toward fixes that stay faithful to the original. Years of hands-on modding, programming, and debugging experience are what make that guidance possible.

AI is part of modern programming almost everywhere now, at least in some capacity — autocomplete, refactoring, bug triage. But yes: there's also a port being worked on by hand — Silent Engine, by a contributor who works directly on the decompilation (github.com/Sezzary/SilentEngine).

Beyond porting, they're deobfuscating the code — turning the raw, machine-recovered functions into clean, properly named, human-readable source. That matters a lot: readable code is far easier to maintain, fix correctly and build on, and it benefits the entire decompilation effort, not just one port.

Cleaner, more readable code. That's a big deal for preservation — human-readable source is something the community can understand, maintain and keep alive long-term — and for modding, since clear code makes it far easier to find, change and extend the parts you want without breaking everything else.

The main one is readability. Because this port leans on the raw decompiled code plus an AI-assisted porting layer, the source is harder for a human to read and reason about than a fully hand-cleaned port would be.

Some game data is also still "unmatched" — not yet recovered byte-for-byte — which can complicate things. AI is good at working around those gaps, reconstructing or substituting the missing pieces so the game still behaves correctly.

That last fraction of a percent is mostly code that hasn't been matched byte-for-byte to the original compiler's output — it isn't strictly necessary for the game to run correctly. The port already builds and plays the full game start to finish.

And because it's built on top of the decompilation, whenever the upstream project closes that gap or improves something, those changes can be merged into this port.

Yes — this port is intended to be moddable. Some things may take longer to crack open than others, depending on how the engine is structured and how much we can change without destabilizing the code.

I plan to use AI to help build modding tools and expand functionality over time. How far that goes depends on how cooperative the engine is and how much compatibility we want to keep while we do it.

Yes! Just message me, or post it on GitHub via the issue tracker above. I'm most likely to see it fastest in the PSX Decompilation Discord, in the Silent Hill channel — this port has a dedicated thread there.

No game assets are included with or distributed by this port — no code, textures, audio or models from the game. To play, you must provide your own data, ripped from a legally owned copy of the original Silent Hill. The port only runs your data; it doesn't give you the game.

You are not obligated to support me in any capacity, and I do not provide any benefits for doing so. However, if you truly insist, I have a Ko-fi link in the sidebar. I do not expect to make any money from this project, but Claude does cost money to use, so any amount is appreciated. You could also just subscribe to my YouTube channel — that alone helps me out a lot.
