OK, I don't know how to exactly categorize this, but I'm trying to find a list of unique PSone (PS1) game/demos that never had a true commercial release but have since become "available":

For example:

Developer's Demo/Hear It Now, Play It Later
Titan A.E. demo disc
Thrill Kill (unreleased)
Torc - Legend of the Ogre King (unreleased)

Are there any other interactive game demos/unreleased/beta Playstation 1 games that have leaked or become available to the general public/internet? Basically, I guess it would be anything for the PSone that you could not purchase at a retail outlet that have either had a free release (i.e. demos) or leaked release (i.e., betas).

What am I missing?
