I tried unsuccessfully with DF1 mostly because cheatengine would crash the whole computer if I'd try to "see what writes to this address".. Tried to get the cheatengine guy involved a bit, but gave up pretty quickly because I could create good enough macros w/out reading memory.
Before I give it a shot just wondering if anyone has had any success or failure with it yet. Mostly just interested in player stats (health, mana, stam) and coordinates + facing.
