if no-intro naming rules are being followed, shouldn't demo discs be done like this?:
Game Name (Demo)
rather than
Game Name (Europe) (Demo Version)
or
Game Name (Europe) (Trial Edition)
or
Game Name (Europe) (Taikenban)
or
Game Name Demo (Europe)
etc
i.e. ignoring whatever way the on-disc/on-box text calls the demo, and just giving it the generic label "demo"
and optionally an extra "kiosk" label, like no-intro does.
e.g. Game Name (Demo) (Kiosk)
or maybe Game Name (Kiosk Demo) or Game Name (Demo, Kiosk) instead
