If you just want to get money or change some stat on your ship, you should check that save file is almost a plain text XML file(seems to have some binary components so I just edited in a HEX editor).
I found it in the user directory under Application DataUnityWebPlayerPrefschat_2ekongregate_2ecom and simply changed the money.
For some reason it wouldn't let me add more digits than were saved so I did have to buy a few things, then "9" out the money, go back, sell something, and repeat to get like 999,999 but it worked.
