Epsxe to psp game save conversion

Can anyone help me I have a ffvii game save that I have been playing on epsxe and have just downloaded the game off the ps store for my psp is there any way I can convert the save file to the psp so I don't have to start over? I have a PSP 3000 so no custom firmware.Thanks in advanceDan

The conversion process requires CwCheat, which can only be run on CFW.

So there no way I can do it on my computer then copy the file onto my psp?

Anyone?
