erm, even without qmc2 help, you can setup snapname to save to a system folder (not a softlist folder, though), named after the soft shortname

so e.g.

Code:
-snapname %g/%d_flop1


will save snaps for a foo_game taken from c64_flop.xml and run in c64, to c64/foo_game.png

and

Code:
-snapname %g/%d_cdrm


will save snaps for snaps for a foo_game taken from psx.xml and run in psj, to psj/foo_game.png
