Project mention: Show HN: I wrote a Christmas-themed Space Invaders clone in 8086 Assembly | news.ycombinator.com | 2025-12-24
I've had a goal for the past three years to learn Assembly language. This December, I finally put some real effort into learning the language. I followed the tutorials in Oscar Toledo G's "Programming Boot Sector Games" and used Gemini as a tutor to help explain the concepts I was stuck on. It was tempting at points to vibe code some of the trickiest pieces, but I found resisting the temptation and using Gemini just to be an expert tutor to answer my ignorant questions brought back the joy of coding again. The result is a Christmas-themed Space Invaders clone written in 8086 Assembly.
The code isn't perfect, and neither are my line-by-line comments, but it's a good exercise if anyone else is trying to learn a language.
The game compiles to a .com file and runs in DOSBox. I'm not trying to fit it into a boot sector (512 bytes) like the original tutorial (https://github.com/nanochess/Invaders/blob/master/invaders.a...), so my code assembles to more verbose (around 700 bytes).

This lead to the creation of vxdiff, a pure assembly AVX512 based reimplementation of the core odiff algorithm. It only implements the default set of odiff options (and odiff has some interesting options to tweak its behaviour), but it's still a capable tool. It's also easier to start simple rather than trying to implement all the possible options right away.
