- This repository contains the fully reverse-engineered and commented source code for the Atari 2600 classic, Raiders of the Lost Ark. \ Unlike a raw disassembly, this project aims to provide a semantic understanding of the game logic. Variables, constants, and subroutines have been renamed and heavily commented to explain how the game works, from the procedural flute music to the complex collision logic in the Map Room.

THOUGH THE CODE WILL ASSEMBLE INTO THE EXACT GAME ROM, THE LABELS AND COMMENTS ARE THE INTERPRETATION OF MY OWN AND MAY NOT REPRESENT THE ORIGINAL VISION OF THE AUTHOR.

Indus is one of the 12 figures formed by the Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman from stars they charted in the southern hemisphere on their voyages to the East Indies at the end of the 16th century. It was first shown in 1598 on a globe by the Dutch cartographer Petrus Plancius and first appeared in print in 1603 on the Uranometria atlas of Johann Bayer.
