Hex Cheat
The saved game files are in the folder SAVES under the installed folder. They have the names MGSAVE[user supplied] [game supplied]
example: C:MARTIANSAVESMGSAVEPLAYER 00-17
where "PLAYER" is supplied by the player at save time and "00-17" is supplied by the game.
A number of bytes have been found that indicate the number of saves the player has in specific computers encountered during play. Note: The game is saved by using the computer, calling up the game "Martian Mayhem", and selecting "Save Game".
So far hex 07 (8th byte) thru hex 13 (20th byte) appear to be the bytes corresponding to computers with different numbers of stored saves. They can all be set to hex ff to set all the computers to have 255 stored saves each.
