- Well, like most games with saved game files, the way to edit those
- files is to jot down some important statistics while in the game
- (number of credits in the case of Dune II, character statistics in the
- case of RPGs), and then, with the help of a calculator that can do
- decimal to hex conversion, start poking around the saved game file.
- For those who haven't done this sort of stuff before, Intel-based
- machines store binary numbers starting from the low-order byte. For
- example, 1000 in decimal converts to 03 E8 in hexidecimal. This would
- translate to E8 03 in the saved game file.
-
- I just got the game and did some preliminary poking around. The number
- of credits you have seems to be stored in three different places
- (though I haven't double-checked this to be sure). I tried changing
- those three values to something a lot larger. When I got back into the
- game, the number of credits was screwed up. There was what looked like
- a lambda or something in front of the numbers, and instead of
- decrementing when I purchased something, it incremented instead. This
- also had the side effect of giving me effectively unlimited credits
- (at least so far). I think there may some limit on how many credits
- you can stockpile at one time (also possibly compounding the problem
- is that I didn't have any extra storage silos to store these extra
- credits). I didn't bother trying to figure it out since I was more
- interested in learning how to play the game.
-
- With other games like Might & Magic, Darklands, etc., you can do the
- same sort of thing, though sometimes, the manufacturer is a bit more
- clever and "encrypts" the values making it tougher to edit (Ultima
- Underworld adds a delta to the stats and Castles II seems to encrypt
- the entire file).
