And now the C128 version is fixed again. C128 now always uses bank switching, as it should. On the PET you can disable bank switching to gain about 100 Bytes of valuable RAM.

Let's Code MS DOS 0x30: VGA 3D Textmode
New video: Let's Code MS DOS 0x30: VGA 3D Textmode
The EGA and VGA card can do a lot of magic tricks in textmode. This time we will investigate how you can draw a rotating 3D cube overlayed on normal text by utilising the EGA/VGA feature of a second character set.

Let's Code MS DOS 0x2F: Mandelbrot Fractal
New video: Let's Code MS DOS 0x2F: Mandelbrot Fractal
Everybody knows the Mandelbrot set. It is one of the most famous fractals. And it is easy to code! At least if you don't care about speed... So let's try to code it for ancient MS DOS PCs with VGA cards! And there will be color cycling!

One hour to go! Then it's #letscode 6502!
I am planning to do a Let's Code Livestream on Sunday, 8th June 2025, at 20:00 CEST, 18:00 UTC. We will be hacking away on an Infocom interpreter for the Commodore PET -- and I barely speak 6502 assembly! What could possibly go wrong???

This is not enough information and slightly incorrect, Mr. Ferraro! The selected maps go in BL, but how? And if two maps are active, you can choose from 512 characters!

You want to know how to code a game for the Commodore PET, one of the first personal computers from 1977?
Let's Code Commodore PET 0x02: Snakes on a PET

#letscode #commodore #commodorePET
Neato: my Snake game now also runs on 8K PETs. You can trim down printf so that it doesn't support float or long types, which we don't need. This frees up a lot of code, so the .prg is now 3.1K in size!

New video: Let's Code Commodore PET 0x02: Snakes on a PET
In this episode we code a simple game for the PET. It is the classic snake game, where you control a snake that picks up food and grows longer. We learn how to read from the keyboard, and how to limit the speed of the game, as the PET is slow, but not THAT slow.
