PC Engine Hyper Catalog Demo Disks

These Hyper Catalog demo disks are quite hard to come by, not sure how rare/valuable they are, but I'm sure they are popular among PC Engine Collectors. I found one for about $12. The one I have has 2 playable demos, and 3 previews. Best of All Bonk intoduces the demo to you. You use him to select what demo you want to view. It has the following:

Dragon Slayer 2 preview - non playable

Burai 2 - non playable

Nadia Secret of Blue Water - non playable

All of these show Cinema scenes, no actual gameplay footage, though Nadia is a digital comic I believe.

Crest of Wolf/Riot Zone - First level playable demo, with options for difficulty, amount of lives select, and a small sound test.

Winds of Thunder/Lords of Thunder - First level playable demo, it resets after first level.

There is also some listing or catalog system I think, but not sure how it really works or what it does?

It's nice to see previews of games, and have mini demos, it is all quite short, but cool anyways. Does anyone have any of the other hyper catalogs, or know of content to post? I've never been able to find any info. Please post any info you have. There were a number of them released.

If anyone has any other hyper catalogs and are willing to sell please email me or PM me. Thanks
