Looking for a very rare and obscure "x in 1" PS1 Disc

Greetings, assemblergames!

It's been... maybe 7 or so years since I've been after this particular game. It's one of those weird "x in 1" discs containing several demos. This one was called "Gold 4 in 1" or maybe 6 in 1, I can't really remember. The only thing I know is that I played it several times at my father's kiosk when I was little. After he closed down and we moved, the disc got lost and I was never able to recover it. However, I remember the contents in that disc very, very clearly.
- An alpha/beta build of Tai'Fu.
-A ripped version of a PAL "Fifth Element".
-Spyro the Dragon demo.
-Chessmaster.
-Constructor.
-A particular space 'shoot 'em up' that I have NEVER been able to find again.

Maybe there's a couple more games in it, but that's all I can remember. If anyone can help me, I'll gladly give you more info to work with. Also, I will try my best to work with you guys to search for a clue of where I could find this particular 'demo disc'.

Thanks in advance!

 

Sounds like this one:
5-in-1 Gold: Constructor, Chess Master 3D, Tai Fu, Mass Destruction, Fifth Element, + some demos and intros, PAL/NTSC selector

Yes, I've been to that page before and I've tried to contact that person to no avail...
