Is ripping Sprites possible from this visual novel? (Piece of Wonder-2002)

[Paraemon]

GARbro is a pretty good Visual Novel extractor, though admittedly I haven't tried it against those, well, rather spurious D files. If it doesn't work, I recommend looking up ExtractData* which may be part of the Otaku's Toolbox.

* But be wary - quality is extremely poor when extracting with this secondary suggestion, as it typically makes images .bmp and thus removes transparency.
