personally i think this has nothing to do with the data.pak file. the index of a copper is 9901, if u go and search it in the data.pak file with WinHex it will b about at line 36759040 or at 36759060 depending if u use the F7 thing or not.... anyway, if u scroll farther u will see the code for the gold and the silver argates. take a close look at their codes and u will c that they r the same except fot the words "copper", "silver", and "gold". so if the code doesn't change for the argates but their effects do, then editing the data file will probobly not do anything. if any of u guys have time, u can try to experiment with the code, but i thinik its useless. anyway, good luck trying to find this bug cuz it would rly be awsome if nubs like me could make +7 stuff XD.
