Disassembling a C64 Game from Scratch: Jeff Minter's Gridrunner

In plain words

This is a detailed technical guide to reverse-engineering Jeff Minter's Gridrunner, a classic Commodore 64 game. It walks through the process of disassembling the original game code from scratch, making it useful for retro computing enthusiasts, game developers interested in historical techniques, and anyone studying 1980s assembly language programming. The guide breaks down the game's architecture and mechanics at the code level, providing hands-on learning material for understanding how early home computer games were constructed.

  Unity like game editor running in pure WASM2023 · raverie-us.github.io · ▲644

  In the wake of all the Unity nonsense, just wanted to toss the Raverie engine into this mix :) We’re building off a previous engine that we worked on for DigiPen Institute of Technology called the Zero Engine with a similar component based design architecture to Unity. Our engine had a unique feature called Spaces: separate worlds/levels that you can instantiate and run at the same time, which became super useful for creating UI overlays using only game objects, running multiple simulations, etc. The lighting and rendering engine is scriptable, and the default deferred rendering…

  Hi, As a 8-bit C64 game coder in eaarly 90ties and currently mostly FE-focused dev, decided to give a go to a simple retro game archive. This is purely fun project - so i decided to post it to HN, mayne it'll resonate :)

  My platforming game written in C 892023 · zamfofex.neocities.org · ▲127

  I have been working on this game somewhat sparsely for the past three years or so. However, it is still in a very early stage, and there is a lot of work to do. One of my friends encouraged me to post about it here, since he felt people might find interesting how I don’t use any libraries for it. The game can be played on a browser by virtue of WebAssembly. There are native ports using either MiniFB or SDL2, but you have to build those yourself. I decided to write the game in C because I feel like it is a simple language that a lot of people can understand well enough, and I didn’t think I…

  Talanoa▲337

  Hi 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…

  After 2.5 years on my side project, it has hit £500/month revenue▲647

  It's been a long slow hog and I almost gave up a few times (more than a few) but when covid hit this year it gave me some time to really focus on my product. There were stupid user journey things that I knew needed fixed. There were some features I knew needed added. And I knew the pricing was wrong. I spent some hardcore time working on these things back in March / April and since then my MRR has continued to grow. My product is SongBox (https://songbox.rocks) - it's an alternative to things like bandcamp and soundcloud for creators who need to share audio files privately.…
