What StarPSX is

StarPSX is a Sony PlayStation 1 emulator for Linux, macOS, and Windows, written in Rust. The project describes it as lightweight and says it has no external dependencies. It opens with a graphical interface by default, and command-line startup options include auto-run, full-speed mode, debugger view, and VRAM display. Its component status lists full analog gamepad support and both per-title and shared memory cards as implemented. StarPSX requires a PlayStation BIOS image; its README recommends SCPH-1001 (NTSC-U), the version used for testing. The project points users to GitHub Releases for binaries and lists an Arch Linux AUR package named starpsx-bin. Its compatibility list covers tested NTSC versions and marks Crash Bandicoot, Metal Gear Solid, and Silent Hill as working, while noting that working games may still have minor issues. PAL timings are not yet supported. The project also reports GPU visual bugs, CD-ROM timing issues and unimplemented commands, and no SPU sweep-volume implementation. StarPSX is free and identifies its license as GPL-3.0.

StarPSX suits people looking for a free PS1 emulator on Linux, macOS, or Windows, including users who want either a GUI or command-line startup options. Its listed gamepad and memory-card support may suit players who want those emulator functions, provided they have a PlayStation BIOS image.
