Snowdrop OS v10 (homebrew operating system from scratch in assembly language)
Snowdrop OS is my homebrew operating system.
It is very simple, and is programmed from scratch, using only assembly language (for the x86 processors). It has a custom PS/2 mouse driver, serial port driver, and supports basic multi-tasking.
It comes with a Tetris clone and a multiplayer (over serial port) snake game, also written in assembly language.
Also includes a file manager, text editor, and a graphics library which can render BMP image files and software sprites.
