How rip sprites of Virtual Jaguar?

[adriano gt]

hi, people 

well, I'm looking for a way to rip sprites from a game of jaguar atari.
I have only one .rom file.
It works only on the virtual jaguar.
I tried using two programs to view the sprites:
_Jagview and
_view_jag

... but I did not succeed

Does anyone know other ways?
