A small, bootable game written in x86 Assembly inspired by Space Invaders

Use macros instead of raw constants to improve readability

The code uses raw integer constants at many locations. Those should be replaced by #define macros with appropriate names to improve readability.

Colors

Colorize the game output.

Game Score

Record the game score.

Video Buffer

Add a video buffer as the new display target. Only print the buffer once every frame in order to minimize the amount of video interrupts.

How to make a bootable flash drive?

Hi, thanks for sharing this cool project!

I am unable to make a bootable flash drive. I tried to dd the generated image.img onto my flash drive but it still wouldn't boot:

# /dev/sdc my flash drive
$ sudo dd if=image.img of=/dev/sdc

I was able to make the asm_snake project bootable by going through their README. But I'm not sure how to make this one bootable.

Project Direction

so, I want to spent more time on this project in the future.

I have some feature idea.

• Coding other than x86 assembly
• Recoding of score (time , number of killed invader etc)
• Adding game sound
• Coloring characters
  etc (reference: https://www.youtube.com/watch?v=MLSSxLe_AFE&)

Other than this project

• Creating other games in assembly (And creating games pack)
• Creating Educational tools of assembly(Because, many young people want to understand assembly but they think that it is difficult to understand assembly in japan(maybe around the world), so Educational tools that to learn by writing code are very useful for them)

Your code is nice and there are many things to learn!
Let's do the project for a long time!

check_game_state subroutine is not called from anywhere

Hi @flxbe !

check_game_state subroutine in game.asm is not called from anywhere.

A couple of thoughts:

1. To Delete to check_game_state subroutine in game.asm.
2. To Call check_game_state subroutine from space-invaders.asm.

Which is better?

Best regards,
