Here’s how we bring native 960×544 rendering and first-class touch to PS Vita without changing the app. Engineering deep dive ↓ pocketjs.dev/blog/pocketjs-…

PocketJS 0.4.0 is fully open source. Source code and Vita setup ↓ github.com/pocket-stack/p…

PocketJS now supports PS Vita. ⚡ Native 960×544. Smooth touch pan + pinch zoom. A major milestone in our cross-platform journey! 👾

@xyaobo Yes, Linux in our plan. For example, the Trimui Smart Pro is very friendly for custom GUI stack.

@pocket_js It is support linux？

We got 1,000 followers in one week. 🎉 Thank you for joining us this early! More platforms, more experiments, and many more impossible things on the way! 👾

@metruzanca Thanks!

@pocket_js I have a buddy at Figma. I'll send this his way.

Please tell us you’re sending this to your colleagues at Figma 👻

Modders have brought Counter-Strike-style gameplay to the Sony PSP with a new open-source project called OpenStrike. This isn’t a port of Valve’s Counter-Strike, it’s a clean-room recreation built from scratch that captures the classic gameplay while avoiding Valve’s copyrighted code and assets. OpenStrike runs at the PSP’s native 480×272 resolution and achieves a locked 60 FPS on original PSP hardware. It is currently a single-player project with bots and round-based matches, Multiplayer is still in development.

Already cooking 🧑‍🍳 We’re aiming for pixel-perfect!

OpenStrike is a clean-room rewrite in Rust and TypeScript, built to be extensible and cross-platform. PSP is only the beginning. Here’s a Linux KDE UI built with @vuejs by @TeaboxDev from our Discord community. Imagine using Vue to build UI for Counter-Strike, or any 3D game!

@pocket_js Wait wait wait… So is “Can it run Doom” now changing to “Can it run Figma”? 🤨😂😂

Абсолютно невероятные вещи происходят в мире PSP

@slmn_sh Only PSP now, but we can make it cross platform 😈

@pocket_js wow. does it work on any console or just psp?

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.

Counter-Strike on a PSP? Yep, it works. OpenStrike hits 60 FPS on original hardware using Rust, JavaScript and PocketJS. It’s a smart look at how far Sony’s handheld can still be pushed. #PSP #CounterStrike #RetroGaming generationamiga.com/2026/07/10/cou…

Here is how we made it: pocketjs.dev/blog/pocket-fi…

Didn’t expect a Vita port this soon 🤯
