Source code of some commercial games, with useful information.
Game-name links lead to original source archives; convenient ports are listed separately.
Reconstructed or recreated games have unlinked titles and a marker after the original platform: (reconstruction) for source recovered through reverse engineering, (reimplementation) for a replacement engine reproducing the game, and (remake) for a recreation with substantial gameplay or presentation changes. The marker and Language entry describe the main project linked in the Port(s) column.
The ports list includes those who are updated to make the project easier to understand/build, while being faithful to the original; ports adding/changing signficant features are generally not included.
Release dates refer to the listed platform and use YYYY/MM where the month is documented, or YYYY otherwise.

Boulder Dash is represented by a commented C64 disassembly for research, with its annotations, generation scripts and archived listing; a complete rebuild has not been established. The readable listing is published by the author.
Maniac Mansion is represented by a commented C64 engine and disk-loader disassembly for research; a complete rebuild has not been established. The separate game-script disassembly documents the game logic.
Prehistorik is represented by Olduvai's faithful Classic DOS mode; optional enhanced presentation is also available. Prehistorik 2 is represented by a recovered Python source port. Both require original game data.
Tyrian is represented by OpenTyrian, a C translation of the original Pascal/assembly source licensed to the port developers; the original source is not publicly released.
SimCity is represented by the Unix/X11 source lineage released as Micropolis; its Language entry refers to the historical C/Tcl version. MicropolisCore is the later C++ refactoring.
