An overview of the Spectrum Next’s Layer 2 bitmap display

I found a real bitmap display for the RC2014 and here’s how I made it work.

How I wrote a game in a week using just my web browser.

How writing code for a 40 year old computer made me a better computer science teacher.

Let’s draw a lit 3D scene without defining any 3D objects. Yeah no it confused me too.

Today I figured out how to draw a line, and then make it wiggle using some basic maths.

Let’s spend this week learning about GLSL and making fancy images from code. The first one, a nice computationally intensive fractal.

Today’s lesson in curing headaches by banging your head on the wall until they stop involves joysticks and mice. This is a bit technical, so ensure your seat back and tray table are in the upright and locked position. Please keep all arms inside the ride at all times.

How to write GameBoy Advance (GBA) homebrew using modern tools and systems in 2020. Compilers, editors, debugging and more!

This isn’t the definitive way of doing things, but it’s a way that seems to work for me. Also you might read this and think it a bit convoluted and full on. I didn’t create it all in one go, it’s a workflow that has evolved over time.

Back in the mists of history, sometime around the 90s it was quite common for games and demos to display text on the screen. Since we’re talking about old computers with barely any usable RAM, the text was stored as images. A giant single image with every character placed within it. To display words programmers had to be a bit inventive. That’s the topic of today’s post.
