A small intro/demo type thingy as the result of me trying to "dust off" and re-learn some 30 year old assembly.
This took most of my Christmas break. Starting out I was really stumped by some of the VERA stuff: The registers, the layers, loading data, 4bpp colors, high bit addressing. But, eventually it started to make sense a bit.
All this would have been impossible for me without the very helpful blogs at https://www.8bitcoding.com/ and https://justinbaldock.wordpress.com/category/retrocomputing/commander-x16/. The Vera Graphics Convertor was also very useful.
I used KickAssembler for the code. I've uploaded the .asm file as well, just in case it's useful for anyone else learning this stuff.
