Commander Keen Dream's saved game files are stored in SAVEGMx.CKy The same format and function is used for all versions of Keen Dreams. The files are of variable length and consist largely of a memory dump. First is Keen's inventory, then the level and finally the sprite data. (Music and tile property data is not saved for obvious reasons.)

The Dave 3-4 Saved Game Format is how saved games are stored in [[Dangerous Dave 3]] and [[Dangerous Dave 4]]. It is related to the [[Commander Keen 4-6 Saved Game Format]] and the [[Bio Menace Saved Game Format]], and is notable in that it doesn't store the state of the saved level. As such, when restored, the game starts the level from the beginning. The name of the saved game is kept as the filename, and both games display a list of saved games when restoring. Games can be loaded\saved to subfolders in the game directory.

Note that saving a game directly after entering a level causes the game file to be corrupted for some reason. (Values in the saved game file are not equal to what they should be.) but restoring this game will work fine.
