When the PlayStation was on the market, you may remember seeing those Kiosk units in retail stores. The units came supplied with what is known as a Video IDU Test disc, used to test the CRTs on those kiosk units which were called IDUs or Internal Display Units for short.

At this point, there are two Video IDU discs found and dumped by the Redump community, both of them are PAL-Exclusive. According to crimson-ceremony.net, this particular test disc came with a Memory Card that is needed to operate, similar to those Pub Demos that came later on. But to my POV, it actually boots fine without one. The disc will make a Memory Card save that, much like the Pub Demo save files, is nameless, invisible, cannot be removed with the internal Memory Card manager and can once again only be deleted by either formatting the card or using Unirom or any game or cheat disc/device that can delete saves. Unlike the Pub Demo saves though, it is only one single block (8 KB) big. It carries the header VIDEO0 and doesn't have the serial SCED-00988 attached to it, like how every Memory Card save including those of the aforementioned Pub Demos should have.

Thankfully, unlike those Pub Demos, it won't format an inserted Memory Card. But when you attempt to boot up a disc with a full Memory Card, it will refuse to boot, as I show it in another video.

The VIDEO0 file itself though only has numbers from 1 to 6 written all over, when it is supposed to save statistics for the different trailers played.

As for what crimson-ceremony calls the "Sony Games Reel" being the one video played on a loop, it is essentially the Demo One intro used in Versions 1 to 5, with music that is used in versions 3 to 5. I play the video for about 20 times and then I turn it off and examine the save file using Unirom and its integrated Hex Editor for game saves.

There's one other Video IDU disc that shows trailers for the various games advertised on it, but doesn't require a Memory Card and doesn't make a save file to save statistics on it.
