#C

This video explains the Von Neumann architecture and demonstrates, with real BBC BASIC and C code, how computers fundamentally cannot tell the difference between data and executable instructions.

How to write code for the Agon Light (and Console8) using C instead of BASIC, under Linux. It might work with WSL2 in Windows, and it might work on a Mac.

Come back to a time when 640k was enough, and when a 486 DX2/66 was considered a fast computer. None of this modern multi-core rubbish or branch predicting exploitable nonsense here. Just you, me, DOS and a C compiler.

In this video, I’ll show you how I built a tilemap system from scratch in C for the Agon Light, and integrated it into my existing game engine. Getting the physics engine to handle collisions with the tilemap was no easy task, but I’ll walk you through how I made it work. On top of that, I explore some game design, sketching out ideas for where the game is heading.

Join me on a journey as I attempt to write a game for my Agon Light using nothing but raw C programming. In this second episode I figure out how to make a very basic 2D rigid body physics system work.

Join me on a journey as I attempt to write a game for my Agon Light using nothing but raw C programming. In this first episode I figure out what kind of game to make, look at some shareware games of the past and get a basic game engine working, using nothing but C code – no external game engines or modern development tools.

Early computers weren’t powerful enough to draw full-screen moving graphics, so they had to use clever tricks. Let’s explore how Nintendo’s techniques for creating tile-based games on the NES can be applied to modern hardware. Using these methods, I built a scrolling tilemap system for the Agon Light using C programming.

The end result is a fairly pretty scrolling text routine that demonstrates how to draw multiple bitmaps to the Agon Light’s display using VDP commands.

This builds on my previous Agon Light C Programming video where I explained how the Agon Light’s screen works, and how to draw lines and shapes.

Dive into the exciting world of DIY hardware hacking. Join in as I explore joystick integration, keyboard inputs, and serial debugging using the versatile Agon Light platform. Delve into the technical intricacies of GPIO pins, assembly language programming, and C compiler usage for low-level development. Discover the power of computational thinking, boolean logic, and UART serial communication as we navigate through hardware interfacing challenges.

Instead of bashing away in BASIC, it’s possible to do some coding in C on the Agon Light. Let’s find out how in this introduction to an ongoing series where I figure out the Agon hardware and work on a game. I have no idea what game I want to make, and I’m not entirely sure how to achieve some of the necessary functions, but it’ll be fun figuring it out and I hope you come along for the ride!
