All my games used either my original engine or my later SAGA engine. I have since built on that engine and created CLO+# (pronounced Clopas Sharp)

The reason the later games may not be available would also be due to licensing. The licenses for the Marvel games and Buckeroo Banzai have all expired and can't be legally used anymore.

Keep searching on the internet though. There are users and user groups still playing them :)
