I am not entirely sure what people have against the star wars skin.
Still get the new ezfla_up.bin from the EZ4client download at
http://www.ezflash.cn/downloads/ (or that one I just linked, it is all good), patch it with kuwanger's tools I linked (this will get you the reset patch) and then add it to the directory with ezskinner (
http://ezflash.sosuke.com/viewtopic.php?f=13&t=1590 ).
The rest is just EZSkinner usage.
EZSkinner is based on visual basic which MS nerfed quite hard, to that end if you have a XP virtual machine or a machine with XP still on it then you are probably in for a better time. You can try fiddling with VB runtimes, alternatively the tools that ezskinner uses are just DOS tools.
