Commander Keen 1-3's saved game files are stored in SAVEDx.CKy. The same format and function is used for all 3 episodes of Keen. The files are 92 bytes long and consist of the following:
Data type | Name | Description |
---|---|---|
UINT16LE | gotBattery | Have battery part? 0=no, 1=yes |
UINT16LE | gotVacuum | Have vacuum cleaner part? 0=no, 1=yes |
UINT16LE | gotJoystick | Have joystick part? 0=no, 1=yes |
UINT16LE | gotPogo | Have pogo stick? 0=no, 1=yes |
UINT16LE | gotWhiskey | Have whiskey part? 0=no, 1=yes |
UINT16LE | gotKeycardR | Have red keycard? 0=no, 1=yes |
UINT16LE | gotKeycardG | Have green keycard? 0=no, 1=yes |
UINT16LE | gotKeycardB | Have blue keycard? 0=no, 1=yes |
UINT16LE | gotKeycardY | Have yellow keycard? 0=no, 1=yes |
UINT16LE[16] | levelDone | 16 values for each level, 0=incomplete, 1=completed. With the 32 levels patch this becomes 32 1-byte entries. |
INT16LE | numLives | Number of lives Keen has left |
UINT16LE | ammo | Number of shots Keen has left |
INT32LE | score | Player score |
INT32LE | posX | Location on world map, in "global" units (256 units = 1 pixel, 4096 units = 1 tile) |
INT32LE | posY | Location on world map, in "global" units (256 units = 1 pixel, 4096 units = 1 tile) |
INT32LE | viewportX | Location of left of visible screen, in "global" units. Usually player location minus nine tiles. |
INT32LE | viewportY | Location of top of visible screen, in "global" units. Usually player location minus three tiles, but variable. |
UINT16LE[9] | cities | In Keen 2, cities saved. 9 2-byte entries, the last seems not to be a valid city, but is kept in memory. |
Keycard values are usually set to 0 in saved games, since saving the game is only allowed on the world map and the game takes away all keycards when exiting a level in any way. Because this behavior only changes the keycard values when returning to the world map, loading a saved game that has the keycard values set to 1 will allow the player to enter any level with the keycards still in the inventory.
Notes
- Keen needs the 'pogo got' value in all 3 episodes of Keen, even though he's never without it and it's never displayed in episodes 2 or 3.
