You are so close from the truth :-) I wrote demos some while back (~ 1990 -> 1998 roughly). They were running on the hardware of that time (including specific soundcards like the Gravis UltraSound), using modified DOS modes etc. As years passed, it became difficult to run them, because the hardware was harder to find. Ultimately I wasn't able to watch my own creations anymore! At some point though, I discovered DOSBox (the emulator). But running it on the available hardware in say 2005 would not give anything good! So I had to wait more years until technology improved (good enough to ensure the emulation would run fast & without too many glitches, but also fast enough so that video can be captured decently), until 2019 roughly, when some friend from back then captured my own work on their brand new PC (https://www.youtube.com/watch?v=UVwesW3PSwg https://www.youtube.com/watch?v=UVwesW3PSwg). So yes, it feels like archeology to me!
