Converting a Skies of Arcadia UK save to US

Hi, I need some help on how I could possibly convert a Skies of Arcadia UK save to a US one that would work on the US version of Skies. I already know how to get the file to my computer, and how to edit the save file. I just don't know what location and values need to be changed to make it work. I have done something similiar with a Shenmue US save to SHenmue II UK, so it must be possible somehow. If anyone knows a web page or any other info on how to do this I'd appreciate it.
