>Also, does anyone know if the addresses change every time you start a new game? I saved all of the previous edits I did last night, and when I loaded the game again today, the values were all like 21362136 and stuff. Really, stupidly high numbers, obviously not what they were in-game.
Yes, they do change a little. But stay in same meory block, thats how trainer works, a man, who is writing it, just gets the block he should change and then searches in that block for 'markers'. You can do it yourself with CoSMOS, check the manual.
Not only does it change each time you start a new game but it changes pretty often while you are in a game. Freezing the values for items like Alien Alloys wont work for very long and may cause the game to crash. Best to just make sure the value in the game and in CE are the same before altering them to prevent crashes. About every other time I tabbed out of the game to change something the locations had changed, maybe every 5 minutes or so.
