I am still amazed my own minimalist PS1 tutorial series [1] became as popular as it did, given that prior to it basically all learning material on the internet was written around the decent-for-the-time-but-horrible-now Sony SDK and often based on 30-year-old example code full of 30-year-old C practices (in particular the complete disregard for aliasing and concurrency, which resulted in plenty of headaches once people started using those ancient libraries and example code with modern GCC). We even have bleeding-edge C++ SDK options [2] complete with an STL and coroutine support, so if anybody here wants to try their hand at PS1 homebrew development I would highly encourage checking out the modern tooling we have now.

If you want a good horror bedtime story, you can peek at OpenBIOS within the pcsx-redux tree: https://github.com/grumpycoders/pcsx-redux/tree/main/src/mip... The commentary section starts with "The retail PlayStation BIOS code is a constellation of bugs and bad design." and it gets worse after that. There are hidden gems inside the source code comments of that simili-reconstruction.

Hey all, I posted this as I'm currently working on a PS1-related project that I hope to release soon. Does anyone have recommendations for a PS1 web/js/wasm emulator? PCSX-Redux [0] has been great on desktop, and DuckStation [1] as well. I found a few js/emscripten efforts, but if anyone has a rec, I'd appreciate it. Thanks!

PSn00bSDK maintainer here. Unfortunately the project cannot really be considered clean room; the original versions of most libraries contained code that was either lifted straight from Psy-Q disassemblies or heavily inspired by them. I have since rewritten pretty much all of it (with the exception of the GTE library which still has some Sony code) using only Psy-Q API documentation as a reference, but the "ship of Theseus" nature of the rewrite makes it hard to argue that it is a clean and legally safe project. On the flip side, there are plenty of other open source PS1 SDK options that have been written from scratch, do not reimplement the same API as Psy-Q and can thus be considered clean for the most part. Here's a few of them: - https://github.com/grumpycoders/pcsx-redux/tree/main/src/mip... - https://github.com/ChenThread/candyk-psx
