    The idea is actually quite simple. As a Japanese learner and a coder, I've always wanted there to be an open-source, 100% free for learning Japanese, similar to Monkeytype in the typing community. Unfortunately, pretty much all language learning apps are closed-sourced and paid these days, and the ones that are free have unfortunately been abandoned. But of course, just creating yet another language learning app was not enough - there has to be a unique selling point. And then I thought to myself: why not make it crazy and do what no other language learning app ever did by adding a gazillion…

    So, me (dev) and my friend (designer) have been building a website/mobile app to help users manage their game library (think MyAnimeList, but games) for a little over a year. We launched with a very basic set of features, and have been slowing expanding since then. All the code is open source, and most of the things we implemented were direct feedback from users (e.g. being able to import games from Steam/PSN, and the Posts feature). We don't show ads or have any kind of subscription. This is just a hobby project. Any feedback would be greatly appreciated, as honestly the hardest…

    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, Over the past ~1.5 years, I built an open-source FPGA retro emulation handheld that can play Game Boy, Game Boy Color, and Game Boy Advance cartridges. To my knowledge, there isn't an existing open-source FPGA emulator that can play physical cartridges like this. One of my main goals was to do all of the pieces myself, and be able to understand every component of it, so I designed my own PCB, wrote the firmware, wrote a Game Boy and Game Boy Advance emulator for the FPGA (using the Chisel HDL), and designed a 3D-printed case. I detailed the design and development process in the…

    I'm making a platform for simple open source games you can play anywhere. Games are all just JavaScript classes and you can read the source of every game on the platform. I started working on initial "games" (mostly rendering tests) in 2018 and eventually built all of the platform stuff around it to make it easy to share games. There's also an in-browser editor available for you to make and publish games all from the browser. Would love some feedback on the games and studio features as well as the platform overall. All of the code is available at https://github.com/homegamesio

    I was looking for apps to track my retro game collection and everything looked.... really dated and not great. So I spent the last 5 months making my own. I've made a lot of apps for other people over the years, but this is the first one I've made for myself. iOS and Android. Let me know what you think!

    Me and my friend built an unique content based Recommendation System, where user can just select Anime or write synopsis and our system will find the most similar anime available. We used Qdrant Vector Database for the Recommendations. Other Features includes, Streaming, Custom watchlist creation and sharing of watchlists. We update our Database regularly and plan to introduce new features in future.
