It seems rather odd that released versions would be included in the wiki. Then the site would mostly hold released demos as opposed to rare unreleased material. Can someone clarify site policy on this?
Appears to be a released demo, matching with the EXE date here http://redump.org/disc/36649/
The wiki claims the source is a CD-R (silver?). Seems very confusing.
Here's another example of a seemingly released demo http://hiddenpalace.org/Dengeki_PlayStation_D21_(Demo_disc)
