Half-Life on a Real PlayStation 1 | Full Hazard Course, Uncut

Half-Life running natively on an original PlayStation 1, captured directly off a SCPH-9002 through a RAD2X capture card. Not an emulator and not a demake: a renderer and game runtime written from scratch in Rust.

This is the full Hazard Course, all 7 maps, start to finish in one sitting with no cuts. The deaths, the retries, the moment I get stuck inside a wall and die, and the audio glitches are all still in it. 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.

Built on PSoXide, a PS1 development suite I have been writing in Rust: emulator, SDK, engine and editor: https://github.com/EBonura/PSoXide

Some of what it takes to fit: BSP traversal doubling as painter's order for the ordering table, PVS culling, 16 colour CLUTs at 4 bits per pixel, LZ4 map chunks streamed into a static buffer, animation frames pre-posed at cook time because there is no FPU and no heap, SPU ADPCM audio and 27 Red Book CD tracks on the disc.

For legal reasons there will never be a downloadable disc image or a ready-to-play build. What will be published is the source code, which is currently sitting in a private GitHub repo. I have written to Valve asking them to greenlight the project, and if I have not heard back in a month or so I will take that as no objection and make it public. Once released you will need your own lawfully obtained Steam copy of Half-Life: the converter reads it on your own machine and builds the disc from there.
