Question about gpSphone

[GuardianAngel]

hi.
well. i downloaded the prog and its great.
now im in a bit of a problem and i wonder if you guys can help me.
the gps makes saves as "svs" files.
the emulator i use on my cpu to play saves as ".sna" files.
i tried to change the extansion of the files but it crashes on the iphone \ crashes the emu.
is there any way you maybe know an emu that reads svs files?
or a way to read svs files, convert them, and so on?

thanks alot.
