ok....i'm kind of a n00b at this...i was looking at Deadly Shadow's tutorial on hex editing, and i tried to do it, but the meta values in the offsets at iron forge's website and on the tutorial don't correspond to any meta offsets in the map when i open the hex editor.....why is this?

also how do you know what values u can change the bytes to to make them do what u want?

okay, you find the offset of the thing you want to change, then you'll get a value, change that value with the the thing you want to change it too
