A list of playable boot sector games, most of which are on github. Fun to play, great to learn from. There are also many cool non-booting boot sectors out there that aren't games (so more like demos), but this page is just reserved to interactive boot sectors / games. This list is also not complete, but not on purpose, it is a best effort collection of games, so if you know of any fun boot sector games, please contribute.
This page lists a collection of 26 games spanning several authors: nanochess, me, daniel-e, shikhin, JulianSlzr, XanClic, QiZD90, darkvoxels, guyhill, w-shackleton, egtzori, VileR, ish_works, franeklubi, and queso_fuego. peterferrie should also be mentioned as he has touched a lot of these games.

Tetris Clone. Full color, no score. This was one of the older boot sector games out there.
