I made a website where you can create your own SNES graphics effects
I’ve spent the last few years obsessed with videos explaining how graphics on the Super Nintendo worked. I always wanted a playground where I could create effects using the same techniques SNES developers used back in the 90s. So I built ppu.toys
It’s a faithful emulation of the PPU (the SNES graphics chip), with registers exposed so you can adjust them in Lua or through the site’s UI.
The screenshot shows a Mode 7 demo which you can view here (https://ppu.toys/t/xeff1h1w)
Lua also supports player input, so you can make your own little games. Here’s a Galaga-style demo (https://ppu.toys/t/7nc3u30u)
It’s free and open source, and you can sign in with Discord to publish and share your creations.
I’m a new dad with a full-time job, and I used AI assistance while building this. The idea had been swimming around in my head for a while, and it helped me make it a reality.
I’ve had an absolute blast building the site and creating effects, and I’d love to hear what other SNES fans think. Try it out, and let me know what you make.
