Now it is your chance to learn NES Programming with 6502 Assembly [Vintage is the new old] [[source]]

Pikuma has released a new course to teach you 6502 Assembly to be used on the Nintendo Entertainment System through a 22-hour-long video. At the end of the course, you’ll have a working knowledge of 6502 assembly language, a comprehensive understanding of the NES hardware, and a toy homebrew game project that we’ll code together from scratch. We’ll start with small examples and proceed to glue everything together in a final project that demonstrates how a simple NES game works.

The course is presented by Gustavo Pezzi is a university lecturer in London, UK. He teaches fundamentals of computer science and mathematics; his academic path includes institutions such as Pittsburg State University, City University of London, and the University of Oxford.

I’ve been taking another course available at Pikuma, targeting the Atari 2600, and it is excellent. I am 30% done, and so far, I like very much the way the instructor presents the information, the code examples and also the visual aid tools (animations, etc). If the NES course follows the same pattern, I am confident it will also be great.
