Invaders

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 ori

Definitely. For example, a boot sector Space Invaders in 512 bytes. https://github.com/nanochess/Invaders

The author has other interesting bootable games, like: - https://github.com/nanochess/Invaders (Invaders) - https://github.com/nanochess/bricks (bricks and paddle) - https://github.com/nanochess/bootRogue (Rogue) If you like learning assembly language/OSDev, his repos are a must to be bookmarked.

Along that line.. • SectorForth - https://github.com/cesarblum/sectorforth - sectorforth is a 16-bit x86 Forth that fits in a 512-byte boot sector. • TetrOS - https://github.com/daniel-e/tetros - Tetris that fits into the boot sector. • BootMine - https://github.com/io12/BootMine - Bootable minesweeper game in a 512-byte boot sector • Invaders game in 512 bytes - https://github.com/nanochess/Invaders The author has written a book called Programming Boot Sector Games. > A crash course into 8086/8088 assembler programming, in an easy way with practice at each step. You will learn how to use the registers, move data, do arithmetic, and handle text and graphics. You can run these programs on any PC machine and no program exceeds 512 bytes of executable code! https://nanochess.org/store.html Examples from the book: https://github.com/nanochess

This guy has written a bunch of boot sector games, although not boot sector games in forth ... https://github.com/nanochess/Invaders

> though I suppose it doesn't do the BASIC thing What's this then? bootOS programs: (Oh yes! we have software support) fbird https://github.com/nanochess/fbird Pillman https://github.com/nanochess/pillman invaders https://github.com/nanochess/invaders bootBASIC https://github.com/nanochess/bootBASIC And one can test the image: "find a pre-designed disk image along this Git with the name osall.img"

What an amazing story, thanks for sharing! I just watched some of TV interviews with the family and saw the rest of his work, and it's pretty amazing. Check out Invaders in 512 bytes [1][2], or Aardvark game for the Atari 2600 ([3]). Also seems he has just self-published a book (as of July 27): Do you would like more details on the inner workings? This program is fully commented in my new book Programming Boot Sector Games and you'll also find a 8086/8088 crash course!
