A PSX emulator written in Rust

ps.rs

A PSX emulator written in Rust

Project goals

1. Cross-compile to WebAssembly targets (dependent on WebGPU)
2. Play a sampling of NTSC-US games correctly
3. Work with open-source/emulated BIOSes to simplify distribution

Building

Run cargo build to build the project. Tests can be run with cargo test.

Running

The emulator requires a BIOS from a PSX, which can be dumped from physical hardware or found online. The bios should have the following hash:

sha1: 10155d8d6e6e832d6ea66db9bc098321fb5e8ebf
md5: 924e392ed05558ffdb115408c263dccf
crc32: 37157331

Place this in a project-root 'bios' folder, and name it SCPH1001.BIN. If your filesystem is case-sensitive, use all upper-case letters.

Then, run the emulator with cargo run.
