Dev ports Half-Life to the PS1, asks Valve if it's cool with that, and says he'll "make it public" if he doesn't hear back in a month

People are really out here porting Half-Life to the PlayStation 1. Manny, of Bonnie Studios, is a self-described "software engineer, guitarist, and game developer from Sicily." His debut YouTube video promises "Half-Life on a Real PlayStation 1," and 14 minutes of glorious 1998 technology revisited with 2026 technology bears that promise out. "Not an emulator and not a demake: a renderer and game runtime written from scratch in Rust," Manny stresses. https://www.youtube-nocookie.com/embed/aEaa9CeCsbQ Manny is more broadly known for {LINK REMOVED}PSoXide, a PS1 development tech stack that, per his https://bonnie-studios.itch.io/ page, covers an "emulator + Rust SDK + game engine + editor + asset pipeline." In this case, Half-Life was written fully for the Rust coding language without reliance on a traditional emulator, and is running on a proper PS1 console – in this case, "direct capture" off an SCPH-9002 model PS1. "This is the full Hazard Course, all seven maps, start to finish in one sitting with no cuts," Manny explains in the video description. The Hazard Course is basically the tutorial prologue for Half-Life – a good sandbox for a demonstration like this. "The deaths, the retries, the moment I get stuck inside a wall and die, and the audio glitches are all still in it," Manny asserts. "It averages around 17fps, holding 20 most of the time and dropping to 10-16 in the widest areas. The capture chain adds about 100ms between the pad and the picture, so it plays tighter on the console than it looks here." As a quick refresher, the PS1 was released in North America by Sony in 1995, Valve dropped Half-Life in 1998, and the significantly more powerful PS2 arrived in 2000. Lauded for its advanced tech and physics, Half-Life launched on PC and only came to the PS2 in 2001.

Which is all to say: squeezing blood from stone. This being a fan effort, Manny says he's reached out to Valve "asking them to greenlight the project" before releasing the source code.

Dev ports Half-Life to the PS1, asks Valve if it's cool with that, and says he'll "make it public" if he doesn't hear back in a month

People are really out here porting Half-Life to the PlayStation 1.

Manny, of Bonnie Studios, is a self-described "software engineer, guitarist, and game developer from Sicily." His debut YouTube video promises "Half-Life on a Real PlayStation 1," and 14 minutes of glorious 1998 technology revisited with 2026 technology bears that promise out.
