Metal Gear Solid: Integral (RE:INTEGRAL)

Drommedhar/mgs-reintegral

RE:INTEGRAL: an unofficial Windows source port of the PlayStation Metal Gear Solid Integral, built from the C code recovered by FoxdieTeam (their decompilation of the game) and the PsyZ platform library. Godot handles presentation and visual modding, and the native runtime handles gameplay, collision, animation state, audio, saves, and timing. 0.3.0 (October 15) brings the Godot renderer and a modding SDK together with the launcher and the preserved “Legacy 0.2” renderer. A preparation step, Prepare.cmd, extracts the data from your two campaign discs using the BIN/CUE images. Mods install as portable zips and there is a guide to making them. The project itself warns that campaign-wide acceptance of appearance, playability, and performance is still in progress. Windows is the only target; Linux is planned. The repository includes the project’s code and patches, and the releases also publish native debug symbols.

You needYour own Japanese campaign discs of Metal Gear Solid Integral: disc 1 (SLPM-86247) and disc 2 (SLPM-86248), as single-track MODE2/2352 BIN/CUE images; other regions and plain ISO files are not substitutes. Plus 64-bit Windows 10 22H2 or Windows 11 and .NET Framework 4.8 for the launcher, and a graphics card with Vulkan (Godot) or Direct3D 12 (Legacy renderer).

Metal Gear Solid (Alexbeav)

alexbeavs-ps1-ports/metal-gear-solid-recomp

A static recompilation kit for the European PS1 release (both discs, SLES-01370 and SLES-11370) for Windows, Linux, and macOS, built with psxrecomp and the recomp-ui launcher. It’s a separate project from coccofresco’s. The published releases are setup kits: a wizard checks your disc and your BIOS, generates the game’s code, and builds it on your PC; on Windows it can download portable build tools. It isn’t confirmed to be playable yet: the README says gameplay testing is still pending and that building it doesn’t prove the game works, and v0.1.1 states that it makes no claim about gameplay quality. On Windows, automated checks cover disc verification, generation, building, launch, and closing; the Linux and macOS packages haven’t been tested on those systems. The game uses the OpenGL renderer, in 4:3. v0.1.1 (September 30) is the latest of 2 releases: it fixes 0.1.0, which asked for the wrong BIOS and looped back to the setup screen after building. The README says the project was made with AI assistance on code, documentation, and investigation, and that Alex tests the game and decides what gets released.

You needYour own images of both Metal Gear Solid discs for PS1, European release (SLES-01370 and SLES-11370), as Redump CUE/BIN; the wizard checks the exact BIN, so CHD and other formats won’t work, and the second disc is needed when the game asks for it. Also your own European SCPH-5502 or SCPH-5552 BIOS (524,288 bytes). Plus Windows x64, Linux x64, or macOS (Apple silicon or Intel); Linux and macOS need CMake, Ninja, Python 3, and a C and C++ compiler.

Metal Gear Solid (coccofresco)

coccofresco/mgsone-recomp

Midnight Ghost Stone: a native Windows and Linux port of the US PS1 release (v1.0, both discs), by static recompilation of the MIPS code, with decompiled C routines replacing parts of the game as they’re checked against the original executable. The engine starts from PS1Recomp, by way of a Crash Bandicoot 3 recompilation, and uses SwanStation as a reference to compare behavior. Instead of reproducing the PlayStation’s drawing, a Vulkan presentation draws the disc’s original models and textures with floating-point geometry, per-pixel lighting, ambient occlusion, new water, fog, and particles, and CRT effects on the cameras and the Codec, at 4K by default and in fixed 16:9; game logic keeps its original timing. It has fast loading, automatic switching to the second disc, quick save states, its own pause menu, and keyboard and SDL controllers with Steam Input; an experimental 60 fps interpolation can only be turned on from the development environment. alpha.1 (October 10) is the only release, marked “untested”, and the Windows build was tested under Wine, not on Windows. The tests cover separate scenes from both discs, both endings, and the credits, but full fights, the jeep chase, and a continuous start-to-finish playthrough are still missing. The README states that the project’s own work is made with AI under human direction, and all 25 of its commits have Codex as author.

You needYour own images of both Metal Gear Solid discs for PS1, US release 1.0 (SLUS-00594 and SLUS-00776), as BIN files or single-track MODE2/2352 CUE/BIN pairs; other regions, Integral, and modified images aren’t supported, and no BIOS is needed. Plus Windows x64 or x86-64 Linux (AppImage or Flatpak) with a Vulkan GPU, and about 1.6 GB free for the import.
