XCOM: Enemy Unknown Cheats
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.

Before you search for Alien cores, search for something you have a ton of. Be it corpses or whatever, find the code for it and make sure it's the right address. Say you found Mutton corpses at the address of 356475C0. Now when you search for a item instead of a corpse, say like Alien Alloys, the address may be 35647644.
When you compare the two, they have the same hex codes up to the last 3.
Using that you can find items your searching for without needing to potentially sell everything you have in order to find the value. The addresses change each time you load a game up, so be warned on that.
