Archive: extract psp-rust-raytracer.zip. It is laid out from the root of the Memory Stick: copy it there, so you have /PSP/GAME/RustRaytracer/.

Start it from Game › Memory Stick. On a PSP Go without a Memory Stick, use /PSP/GAME/ on the internal storage.

About Rust Ray Tracer

Four spheres orbit over an endless checkerboard while the camera circles them. The CPU traces the spheres, with shadows and a bounce off the chrome one, and the PSP's Graphics Engine draws the floor and sky. L and R switch to a rasterised version that takes its shading from the ray tracer. Left alone, the demo swaps every six seconds.

It needs custom firmware or an emulator. The author has only run it in PPSSPP.
