RomM is a self-hosted app that allows you to manage your retro game files (ROMs) and play them in the browser. Think of it as Plex or Jellyfin for your ROM library: it automatically fetches metadata, artwork, and game information from online metadata sources to transform your folders into a browsable collection. You can play games directly in the browser for consoles like the N64, Game Boy Advance, Nintendo DS, and PlayStation 1, using the integrated web emulator (https://emulatorjs.org/). Members of the community have released integrations for Playnite (Windows), muOS…

Hey HN! Been working on this emulator on and off for the last couple years, and thought now would be a good time to try and show it off here. As far as unique features... I think this is the only online GameBoy emulator with support for save files? So there's your reason to exist, I guess. The WASM port was something I had in the back of my mind but I just kept putting it off because it seemed like it would've been a pain in the ass to implement, but all in all I think it took less than a week so that was a nice surprise!
- PPPlay Pokémon to unlock your Wayland session2025 · github.com · ▲124
Hello everyone! I've created a gameboy emulator to unlock my Wayland session and wanted to share this project to everyone here! I've been a Linux enthusiast since I was a kid. What always captivated me was the freedom to customize my system exactly the way I wanted. With Wayland, we've reached an incredible level of performance. It's like turning your operating system into a video game! I've always been fascinated by the blend of fun and the serious, technical nature of an OS. That’s what inspired me to create this project. I started by studying Wayland, its protocol and how to build a…

Clipto MCP▲640Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hey we are Computable. We spent years building trading infrastructure at Jump Trading and Coinbase. From that point of view, compute looks like energy markets before 2000: everything trades through private bilateral leases, there’s no visible price, and nothing can be resold. The same H100 rents at a 2x spread depending on who’s asking, and once you sign a 24-month lease, it can never change hands. So we built a market for GPU nodes, sold by the calendar week. Here are three things you can do on it that you can’t do anywhere else: - Buy exactly the weeks you need. Three nodes for the last…

Parallel agents, diff reviewer, and multi-model comparisons
Dev tools · May 2026 · kilo.ai
Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
