I remember back in the day, when players would exchange host save files over AIM/Email/ect and I remember there were some players who were banned by hosts from having their save files uploaded because they would somehow become godly.

Anyone have any info on this? I'm assuming it was simply opening the file and modifying the variables, but how does one go about doing this? If it is possible to view the contents of a save file, are the variables labeled as they are in the source code? If not I'd imagine it be quite the chore figuring out what does what in order to get the desired results (god mode/inf health/gold)
