Well the thing is that, when you pick items up, they are undetermined until you pick them up. meaning, when you pick an item up it sends a packet to the server and then the server responds with the item to put in your inventory. So you can't edit it. Same goes for everything that you pick up and the way you hit your opponents. Thats all calculated server side and then sent to your screen.
2. and wouldn't it be possible to record the package and edit it as you pick it up more then once? then you would get a lot of random items and maybe something you wanted :P
Btw lilprohacker thanks alot for your hacks
