Welcome to SizeCoding.org

SizeCoding.org is a wiki dedicated to the art of creating very tiny programs for the 80x86 family of CPUs. By "very tiny programs", we mean programs that are typically 256 bytes in size, usually created by members of the demoscene. The size of these tiny programs is measured by their total size in opcode bytes, and are typically delivered as executable .COM files to be run in pure DOS, a Windows DOS VM, or an emulator such as DOSBox. Despite their tiny size, these programs are able to produce amazing graphical displays, playable games, and sometimes music. There are even some surprisingly effective programs in under 16 bytes, such as a maze generator in 10 bytes, and an "Enter the Matrix" screensaver in only 8 bytes.

The intent of this wiki is to help teach x86 assembler programmers the various tricks and techniques used to create tiny demoscene intros. While these techniques can be used for other applications (boot sectors, BIOS and firmware code, etc.), the information presented here is firmly oriented towards the demoscene.

This wiki is still under construction, and is not yet open for business.
