Unlocking all Stages and Levels
There are 13 stages in Luxor and between four and 10 levels for each stage. The cheats used to unlock the stages, levels or both the levels and stages are command line parameters, meaning they are not ordinary cheat codes you can enter during gameplay or into a password screen.
The parameters are as follows: "-unlockstages" unlocks all 13 stages while "-unlocklevels" unlocks all levels, but only those levels in stages which are already unlocked. Finally, you can combine the two, "-unlocklevels -unlockstages," to unlock all stages and all of the levels within those stages.
There are two ways to use these parameters. The simplest way is to navigate to the Luxor game directory and make a shortcut to luxor.exe, which will probably be listed as luxor with a file type description of "Application." Once you have made the shortcut, right click on it and select properties. Find the target line and type in the appropriate parameter after "luxor.exe" so that the finished product reads "luxor.exe -unlocklevels -unlockstages," or some variation of that.
If you prefer, you can also use the DOS command prompt. First, navigate to the Luxor game directory, then type "luxor.exe," a space and then the appropriate parameter, for instance, "luxor.exe -unlocklevels -unlockstages."
