We compiled reactive JavaScript into a cartridge. The same Vue component now runs on a 2KB RAM NES and a Game Boy Advance. No JavaScript engine. No GC. The computed values and UI effects are compiled directly into bare-metal C. This is Pocket Vapor. ⚡️

The Pocket Vapor experiment is now in the PocketJS repo under vapor/. It’s still early, not a release yet. But the compiler, console targets, and cross-runtime parity tests are already here:

How do you run Vue reactivity on a machine with 2 KB of RAM? The full technical writeup:

If yall can add support for switch and Wii U as well eventually you win Pocket js is sick !

They’re definitely in scope. PocketJS aims to cover a very broad hardware spectrum!

If I'm reading the numbers right, it means you can have a form with about twice as many elements before you run the NES out of RAM

Not quite. The ~940 B number is app state on the GBA, not the NES’s total footprint. The NES’s 2 KB must also hold the record pool, computed views, shadow screen grid, and C stack, so this demo is currently capped at 8 todos. There isn’t a generic elements-to-RAM ratio yet; the compiler derives and checks a static memory plan for each component and target.

But no canvas support or way to draw to gba screen instead of canvas?

Here is a JavaScript todo app running on a real GBA! 9KB cartridge size. Fully compiled to native ROM without JS runtime by the Pocket Vapor compiler.

From iOS 6 to Symbian. Pocket Shell now runs on a 2011 Nokia E7, with the same full-screen gestures and fluid animations as the iPod touch 4. This is what cross-platform JavaScript UI could feel like.

We asked how far PocketJS could push 2D UI. The answer was Figma at 333 MHz. A real .fig file, decoded and compiled into streamed tile pyramids, panning and zooming smoothly on PSP! Pocket Figma is now open source.

PocketJS’s animation engine just got a major upgrade, smooth on a $10 iPod touch. We recreated the classic Clear experience with Vue Vapor, including a custom keyboard and touch interactions. More than a decade after Evan You’s HTML5 Clear, JavaScript is doing it again!

Yes, that's Counter Strike on a PSP! Yes, that's DevTools inspecting game UI! Yes, it's PocketJS! Clean room implemented FPS engine, fully open JavaScript mod API, ~12MB RAM footprint, 60fps, fully open source. ⚡️

here's a small project i put together recently - a custom "bare-metal" protected-mode x86 NES emulator. it fits into 1MB RAM and loads ROMs from a floppy disk, no OS required. if you want to turn your old PC into an awkward NES clone with bad sound emulation then look no further.

Super Smash Bros. 64, running natively on iOS and iPadOS for the first time. Not an emulator. BrawlerPad is built on BattleShip, which already supplied the SSB64 source-port core, Apple Metal path, and SDL controller/audio stack. BattleShip ran on Apple Silicon macOS and Android. There had never been a public iOS or iPadOS port. Now there is. The game logic is compiled into a native ARM64 app and runs through BattleShip/libultraship’s Metal/Fast3D path. No N64 hardware is simulated, and no ROM is interpreted at runtime. Smash deserves a controller, so BrawlerPad supports physical controllers through the same input path as the game. Touch works too. I used Codex 5.6 Sol on the iOS integration. Full build guide and source below.

Blake Ilitch and Cole Duhaime, elite prep pitchers, are guiding Brother Rice back into the playoffs. Ilitch threw a no-hitter this season, and Duhaime compiled a 16K complete game. They’re not obsessed with their personal numbers — and that attitude is guiding their young team.

We wanted to show the performance and the insane power of the Static Hermes native FFI. But we don't yet support the all language features needed to compile React Native (soon though!), so we improvised. We imported the bindings for DearImGui (a popular C++ imperative game UI library that renders meshes), and Sokol (an amazing lightweight 3D backend in C) and wrote a small demo. "Imperative UI" means that the entire UI and the state of the screen is recreated on every frame, which suits our purposes to demonstrate SH very well. The demo runs 100% compiled native code. JavaScript runs in every frame and recreates the entire state of the screen. It is portable to all platforms, though the screen layout is not optimized for phone. We wrote the demo in C++ and in JS, to compare, and they both ran with the same performance. In the attached videos you can see the demo running at the stable screen refresh rate - 120Hz on my Mac, 60Hz on a old Moto G5 phone. It includes some widgets, an n-body simulation of planets, a playable game demo, etc.

Javascript, Ruby, and Go all use garbage collectors for memory management. But did you know your SSD has a garbage collector (GC) too? SSDs with high write/delete traffic are constantly being reorganized by the GC, which is built directly into the firmware running on the SSD controller. This is one of the reasons why sequential writes are still preferable to random, even if you aren't using a spinning disk.

We've been very busy working on the turn based combat engine for Former Dawn, an upcoming #RPG for the PC and NES! Watch the whole video; there's a lot going on! Yes, all of this is legal on the NES. No, this is not a mockup. This is our actual game engine! #nesdev #pixelart

I've integrated fluids into my physics engine. Fluids are made of the same particles as solid matter, but computed differently. Phase change is seamless, matter melts and hardens back on temperature change. It runs fast, and world size limits are wider than any game would need.

GTA 5 port now also runs natively on ALL Apple Silicon Macs 🍎 No CrossOver or Wine or any emulator layer used. Same engine as the iPhone port, compiled for M-series chips and rendering through Metal. oh and it’s FREE‼️ Demo is running on MacBook Pro M5 with 24GB of RAM @ Max quality settings, but also tested on many other Macs with as low as M1 chip with 8GB of RAM, all of which comfortably run the game at lower quality presets at constant 60FPS+.
