Currently studying how PS1 SPU works. Will need to implement my own sequence music reader/converter from scratch! See how Persona 2 uses PS1 sound chip nicely. Initially I thought it was CD audio, but no, it’s all sequenced!

If someone has done sequenced music for some PS1 game, let me know. I want to learn stuff, but there’s not much info except for raw specs. I want to know about the creative process/limitations/tricks.

More jams. Love that reverb so much.

What tool do you use to visualise the SPU state?

It's DuckStation's SPU debug window

You are doing a great job, which in the future can help many to create their own game for PS1

Thank you. Yeah, there’s so little tools/documentation/guides out there, need to do a lot from scratch pretty much 😅 My code is already open, but I also plan to write some articles and possibly make some videos about it all in the future.

PS1 SPU is an ultimate 24 voices amiga MOD player :)

Seeing the PS1 SPU in action is so cool. It's how I realized the car selection themes in Rage Racer and Ridge Racer Type 4 are sequenced

You should look after SNES music tutorials, after all, the SPU is nothing more than a souped up SPC700!

After two weeks of programming, my sequenced music finally works on PS1. Previously, I could only play existing PS1 tracks from other games from .SEQ/.VAB/ADPCM files. Making my own tracker format + properly encoding samples was incredibly complex, but I did it!

I implement Silent Hill fog in my (real) PS1 game. It's exactly the same technique that Silent Hill uses (reverse engineered it). It's pretty incredible, looks great and pushes PS1 to its limits. I'll write a blog post explaining how it works later. :)

I’m making some slides for my “how fog works in Silent Hill on PS1” video. And the best way to show how PS1 works is on PS1 itself, right? So I just made the best slide ever… 😂

Working on PS1 stuff... The cat has learned how to jump, btw. (The collision was hard to implement and haunted me for weeks)

i spent the past 2 days making a ps1 inspired version of my character from scratch! she has 1.2k polys-- i wish there were less, but i needed them to make the face tracking work.

Built this farm from scratch by myself. Was all overgrown 4 years ago. All you need is a vision, and to do it! Thought I was going to get fired from my job during Covid so this was my backup plan.

I built a biologically inspired spiking neural network from scratch and it learned with %5 accuracy to do addition :) There is no backpropagation, no artificial loss functions - just spikes, synapses, and dopamine-like reward signals. it uses STDP -> "Spike-Timing-Dependent Plasticity" with modulated rewards This is super fun and I will try to get it to learn with better accuracy. I also need to better understand how all the moving parts fit together Link to source code in comment which has a detailed readme and html with animations explaining how it all works

I downloaded all my ps1/ps2 classics on the new ps3 and I love how they all came with digital scans of their manuals This is something I would love to see the classic games bring back for PS+ Premium on ps5

A historic moment... I bought a CD burner and now my game launches from the CD on a real PS1! I don't have a modchip, so I'm loading it using Unirom, also it takes a while for the CD drive to spin up... so skip to 00:41 if you just want to see the gameplay.

There's more! Herc's Adventures (Saturn/PS1, 1997) is a spiritual successor to Zombies Ate My Neighbors, and it’s amazing. This is the PS1 version.

I animated Lain on PS1. (The animation is somewhat janky, but it's hard to make such a complex animation smooth on PS1 :D)
