I understand the steps and i have iso software to edit and construct my own iso file. When i open the iso file that i am suppose to edit i see and autorun.inf , launchpad.zip , and launchu3.exe.. I know im suppose to edit this to get the u3 to do what i want but i do not know how. Is there any tutorial on how to edit this so u3 works with pstart or what parts i should edit to make it do my bidding. Thx
