Rust for PSP? Meet rust-psp – A Fresh SDK for Homebrew Dev

Big news for PSP homebrew devs: there’s a new kid on the block called rust-psp, and it’s bringing modern Rust power to everyone’s favorite handheld console.

This isn’t just a port or a wrapper — it’s a full-on replacement SDK built from the ground up in Rust. No dependencies on the old C/C++ PSPSDK. Just clean code, better performance, and all the tools you need to make PRX plugins or full homebrew apps.

🔧 What You Get with rust-psp

• Build both PRX modules and regular homebrew apps
• Full system access via native Rust bindings
• no_std and no_main support (because this is Rust, after all)
• Macro-based VFPU assembler for low-level math magic
• 3D graphics support — and in some cases, faster than the original PSPSDK
• alloc and panic = "unwind" support coming soon
• Goal: Reach full parity with user-mode functions from the original SDK

Here’s what a basic module looks like:

#![no_std]
#![no_main)]

psp::module!("sample_module", 1, 1);

fn psp_main() {
    psp::enable_home_button();
    psp::dprintln!("Hello PSP from rust!");
}

Nice and simple. And it runs!

Why This Matters

If you're into PSP dev, this could be a game-changer. No more wrestling with outdated toolchains or fighting with legacy C++. With rust-psp, you get:

• Modern language features
• Memory safety by default
• Easier debugging and development
• Clean API design that feels natural for Rust devs

And yes — it works with existing PSP homebrew environments. Whether you're making a demo, a game, or a plugin, rust-psp gives you the tools to do it your way.

Try It Out

Check out the examples in the repo to get started. The project is still in active development, but already capable of running real code on real hardware.

Want to build something cool for the PSP using Rust? Now’s your chance.

Final Thoughts

Rust continues to prove itself as more than just a systems language — it’s becoming a go-to for retro and embedded development too. And rust-psp is leading the charge for one of gaming’s most iconic devices.

If you’ve ever wanted to dive into PSP homebrew without the pain of C++, now’s the time to give Rust a shot.
