PlayStation Development Network

Hi all,

I'm completely new to PSX development and just starting to explore how the original PlayStation works under the hood. I've always been fascinated by retro console architecture, and the PS1 seems like a great system to learn about low-level programming, MIPS assembly, and game development workflows.

So far, I’ve been:
Reading through the Net Yaroze and PSXSDK docs
Looking into how to set up a working toolchain for compiling and testing

If anyone has tips for: Advice on learning MIPS for PlayStation specifically

I’d really appreciate the help!
Thanks, and excited to be part of this community.

The downloads section here has the MIPS instruction set PDF for the R3000A, which is the same ISA as used in the PSX.

It's quite lengthy, but it's a good start to get familiar with it.
