nes.xml: Fixed board type

Fixed the board type name, which is "NES-SNEPROM" as seen in the existing picture.

Named the dump "0.prg" following the notes in the softlist:
> Note on the filenames: whenever a chip was labeled, the label writings have been used as filenames, so that in principle
>    one could burn back the content on the right chip. When no label was present on the cart pcb, we have arbitrarily chosen the names
>    0.prg and 0.chr (alternatively, 1.prg and 1.chr for later revisions of a game).

(Original released dump file was named "Super Sushi Pinball.nes", not sure how it became in "super sushi pinball (usa) (beta).prg" the previous PR)
