Found a copy of the
Windows 95 game collection CD-ROM that I mentioned earlier.
It's by
media Verlagsgesellschaft and it's on archive.org but I'm not sure if I should link it.
This post mentioned DOS games specifically, not PC games.
There are games on this CD-ROM that I could only vaguely remember or have forgotten completely. Like this neat Arkanoid clone.
Yes, after hitting the skull block you must actually avoid the ball, until hitting the skull block again. Funny game.

I can actually start up the slots games (Cherry Delight Video Slots, Double Dynamite Video Slots, etc.) this way. Using the standalone versions from Archive.org would give "missing .DLL errors".

From this CD-ROM I learned about other classics like Warpath, Slam!, Reproduction Man, Comet Busters, and Warheads.
Warheads reports itself as Shareware 2.01.

Yes, the game I mentioned in my previous post is actually called Bios. Since the game itself has some graphical errors (maybe some missing drivers or incompatibility due to it being run on DOSBox-x) here is just a screenshot of the preview screen:

I will definitely be looking at the other CD-ROMs by media Verlagsgesellschaft soon.
