Jun/04/2019 http://nanochess.org https://github.com/nanochess This a game recreating the Invaders game in 512 bytes, that can be run as a COM file or put into a boot sector of a floppy disk to be run. Move with Ctrl key to left, Alt key to right, any Shift key to shoot. (maybe you'll need to disable StickyKeys in Windows) The previous commit worked with left arrow, right arrow and space key, but you had to press the space key to stop the spaceship. Also didn't have the barriers. Now it's compatible with 8088 (the original IBM PC) but still it has the option for 80286 code in the source code. So you now have to look for a 8-bit compatible VGA card if you want to run it over original hardware ;) A small video of the game running over emulation: https://www.youtube.com/watch?v=pC976eejfms If you want to assemble it, you must download the Netwide Assembler (nasm) from www.nasm.us Use this command line: nasm -f bin invaders.asm -Dcom_file=1 -o invaders.com nasm -f bin invaders.asm -Dcom_file=0 -o invaders.img Tested with VirtualBox for Mac OS X running Windows XP running this game, it also works with DosBox and probably with qemu: qemu-system-x86_64 -fda invaders.img Enjoy it!
