===Patches===
 +
Unfortunately Keen was from an era of computing before downloadable patches were a norm. Instead, a fully patched version of the game would be sent in the mail. The old version had to be uninstalled and deleted and the updated copy installed in its place. As the update is already the full game, it would be illegal to distribute it. Luckily, Several dedicated fans have made [http://dosclassics.com/keen/dl.php?id=of homebrewed patches] to update (or downgrade if you want) every official keen game. These patches edit the files to make the changes, no warez used! The original discussion thread for them can be found [https://pckf.rigeltechnical.com/viewtopic.php?f=1&t=21&sid=90a04012cef1c483fba6131d8da5e810 here].
 +
{{ii}} An unofficial fan fix that fixes additional issues not addressed in the latest official patch can be found [https://pckf.rigeltechnical.com/viewtopic.php?f=4&t=3746 here].
 +
 +
===Episode launcher===
 +
A launcher for the entire Keen series can be found [https://gist.github.com/maxlefou/e6fe35739a1ffad1b85543eb800c36f4#file-keenstrt-bat-L15 here] (runs in [[DOSBox]]).

{{ii}} The executable names (keen*.exe etc.) may have to be edited to fit your particular version of Keen. There are many versions. You could also replace the executable calls with CKPatch scripts if you wish to keep a customized aspect of the game always that way when you run it.
 +
 +
===[http://www.shikadi.net/keenwiki/CKPatch CKPatch]===
 +
CKPatch is essentially a tool needed to load some mods (such as total conversions, or even just simple hacking) into the Keen engine. It does so by "patching" the engine in memory, hence it's name. For simple single script patches for Keen 3, look [http://www.shikadi.net/keenwiki/Category:Keen_3_patches here].
 +
{{ii}} If loading of a mod/script fails, you may have to uncompress the keen executables using [http://www.shikadi.net/keenwiki/UNP UNP] or [http://www.shikadi.net/keenwiki/UNLZEXE UNLZEXE].
 +
 +
===Source ports===

Three reversed engineered source ports are available.

Version differences

Commander Keen in Invasion of the Vorticons

The retail release of the game, which includes the first 3 episodes of the series: Commander Keen in Marooned on Mars, Commander Keen in The Earth Explodes, and Commander Keen in Keen Must Die!

Commander Keen Complete Pack

A compilation pack containing the entire Commander Keen series (excluding the final episode Commander Keen in Aliens Ate My Baby Sitter! and the "lost" episode Commander Keen in Keen Dreams).

All games in the pack are pre-configured to run with DOSBox.

Essential improvements

Patches

Unfortunately Keen was from an era of computing before downloadable patches were a norm. Instead, a fully patched version of the game would be sent in the mail. The old version had to be uninstalled and deleted and the updated copy installed in its place. As the update is already the full game, it would be illegal to distribute it. Luckily, Several dedicated fans have made homebrewed patches to update (or downgrade if you want) every official keen game. These patches edit the files to make the changes, no warez used! The original discussion thread for them can be found here.

An unofficial fan fix that fixes additional issues not addressed in the latest official patch can be found here.

Episode launcher

A launcher for the entire Keen series can be found here (runs in DOSBox). For a modified version of this same launcher that also supports Keen Dreams (for people whom don't have the native Steam version), try the following:

The executable names (keen*.exe etc.) may have to be edited to fit your particular version of Keen. There are many versions. You could also replace the executable calls with CKPatch scripts if you wish to keep a customized aspect of the game always that way when you run it.

CKPatch

CKPatch is essentially a tool needed to load some mods (such as total conversions, or even just simple hacking) into the Keen engine. It does so by "patching" the engine in memory, hence it's name. For simple single script patches for Keen 3, look here.

If loading of a mod/script fails, you may have to uncompress the keen executables using UNP or UNLZEXE.

Source ports

Make space-bar fire

In the earlier Commander Keen games you had to press both the jump and pogo buttons in order to fire, some find that inconvenient.

Use a CKPatch script[2]

Copy the following into a plaintext editor and when saving be sure to give it a .pat extension.

%ext ck3
#Change the controls to: Space, shoot; Enter, status.

%patch $11AF  $5274W

Notes

Some Keeners consider this cheating as it makes firing much easier, removing challenge from gameplay.
If you wish to utilize these changes in mods you will have to integrate this script into the mods' included script.

Notes

  1. 1.0 1.1 When running this game without elevated privileges (Run as administrator option), write operations against a location below %PROGRAMFILES%, %PROGRAMDATA%, or %WINDIR% might be redirected to %LOCALAPPDATA%\VirtualStore on Windows Vista and later (more details).
  2. 2.0 2.1 File/folder structure within the installation folder reflects the path(s) listed for DOS game data.
  3. 3.0 3.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/9180/ in addition to or instead of this directory. The app ID (9180) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
