I've seen these before and they're definitely homemade labels. Not sure if the original intent was to make money reselling them or just make floppy copies prettier with a label.
That horrible font, missing (R) after Konami, label size wrong, label cutting, all edges of label lifting up, the font of "A" and "B" completely different from what it should be, Konami Corporation instead of Konami, Japanese title missing the (R) again, whew.
The demo disc looks similar to the Bloodlines protos in terms of label style, I've seen 2 so far and they look authentic, the content is also undumped as far as I know.
