.ssu file

i want to update my spiderbox 6000 softcam file with my pc, im at a loose end as to what software opens this file for editing ???
i know i can add the keys from the box menu,,,,but would like to be able to do it on the pc " it would be alot quicker"

any help would be appreciated, thanks

thanks for your reply...
updating the softcam the way you mentioned is what i have been doing ,or updating through the network update option from the menu,,,,,what i want to do is open the softcam file for manual editing,,,,like you do with opensource boxes using notepad or similar ,,,,,,i want to know what to use to open a .ssu file.
