im sure it is JED... but ran with out -w -ns(unless you like it that small with no sound) and instead of doing functions like moving to a certain spot.. or talking to a certain NPC.. it just watches for item drops.. and picks them up when one is dropped.
you probably just remove all the AI in the script and just use pickit... just specify what items to pick up, just like it does now for pindleskin, except remove all the script functions so you wont talk to malah, lazurik, or 'go through a protal', or use skills for you automatically(to kill pindleskin).
im sure if you messed around with it long enough, you could figure that out.
