Stealing Ideas From Doom

Part of the fun of making a game from scratch is desinging the systems that run in the background. This time I accidentally try to program a cooperative multitasking operating system. But it’s OK, this is how you do this sort of thing…

Mode X Madness

After learning about Mode 13h last time, I’ve been digging about in the ancient tomes of wisdom and discovered Mode-X. Let’s make a PC’s VGA card do odd things it was never designed for.

Fixing the PC BIOS Boot Screen Recreation

Thanks to @hobbified on YouTube, making the EPA logo look correct was quite straight forward…

Let's recreate a 90's PC BIOS Boot Screen

Because why not, it looks simpler than it really is and we’ll get to fall down a rabbit hole trying to draw the Energy Star logo.

Nostalgic DOS Development Part 2 - Writing our first programs

This is part two, go read part 1 first.

Gamedev the hard way - doing it all myself

Writing games is hard enough by itself, requiring a lot of different skills. So how can I make this even harder? How about I do literally everything myself, starting with nothing but a blank source file and write all the code by hand. No game engines or libraries. If I need something, I need to write it myself. And since we’re doing this the hard way, let’s write games for an embedded microcontroller based around a Z80 CPU.

Agon Light Graphics Tests

It’s the Easter holidays and I’ve got two weeks off work. Amongst highly exciting things like weeding the garden and waiting for a new washing machine to be delivered, I’m doing some programming.

Learning how to draw things on the Agon Light

I’ve been having a bit of a play around with my Agon Light, trying to come up with some ideas for a future video. I’ve discovered it has quite a nice 320×240 64 colour video mode that has just enough pixels to be interesting.

Agon Light Joystick Test 1

I’m working on getting a joystick port working on my Agon Light. They don’t come with joystick ports, but there is a set of GPIO pins that can be read through assembly.
