From the sources
This is a complete decompilation of LEGO Island (Version 1.1, English). It aims to be as accurate as possible, matching the recompiled instructions to the original machine code as much as possible. The goal is to provide a workable codebase that can be modified, improved, and ported to other platforms later on. Note: This repository is for decompilation only and its code is true to the original release. It will not compile for targets other than 32-bit Windows. For a modern adaptation of the LEGO Island codebase with native compatibility for all major platforms and the Web, see isle-portable instead. The reccmp reports compare every recompiled function with the retail binary. The ReproBit…from github.com

I made a Doom-like game fit inside a QR code2025 · github.com · ▲531I sometimes pick up random projects just because I can, this was one of those times. I made it as a week long project a while back this year but never shared here, so thought to go for it haha. I created a game inspired by Doom and the backrooms called The Backdooms under 2.4kb in minified html. (for reference, this entire post would be around 1.8kB haha) I had to use a not popular way of using GZip with Zlib headers (had to write my own script for compressing it, also in the repo) to eventually convert it a size 40 QR code that works right in your browser using Decompressionstream API. This…
Decomp Academy – Learn to decompile GameCube games into matching CJun 2026 · decomp-academy.dev · ▲197Over the past few months I've been heavily involved in the decompilation community. I've been hands-on decompiling a beloved game from my childhood (Star Fox Adventures). I started this journey with zero prior decomp experience—and to make things worse I had never really touched C nor assembly either. Learning how to decompile was challenging. It's difficult to find any good learning resources for it and any open-source projects for this are inactive and/or contain little actual learning material. So I put together Decomp Academy! Decomp Academy is an interactive way to learn how to…

- D1Doom (1993) in a PDF2025 · doompdf.pages.dev · ▲369
I made a Doom source port that runs within a PDF file. I was inspired by the recent HN post about Tetris in a PDF (https://news.ycombinator.com/item?id=42645218) and I wondered if I could get Doom to run using a similar method. It turns out that old versions of Emscripten can compile C to asm.js code that will happily run inside the limited JS runtime of the PDF engine. I used the doomgeneric (https://github.com/ozkl/doomgeneric) fork of the original Doom source, as that made writing the IO fairly easy. All I had to do was implement a framebuffer and…
Development Journey on Game Decompilation Using AI2025 · gambiconf.substack.com · ▲5Hey, ever wanted to fully understand or tweak a nostalgic game that you love? So, I’m documenting my journey on matching decompiling a retro game, step by step, using AI and self-made tools. Three chapters are done, and the fourth is in progress. Matching decompilation is a fun reverse engineering challenge that paves the way to learn more about a game and fully customize it. Let me know your thoughts about my posts and the VS Code extension that I'm developing, called Kappa! Have you ever heard of matching decompilation, by the way?

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
