Currently I am exploring the old arcade ports of the 90s and I have to admit, they are really unique and are playable even today, with graphics and music enhancements. They are much better than the more promoted console versions of that era in many cases.
Nowadays distributors lazily release a rom set with an emulator but at that time they tried to take advantage of the system and even adding extra features like FMV videos and CD music,both for consoles and computers
It is just that those games were not that much promoted because computer game publishers were focusing in advertising adventure, fps, strategy, sports etc
Also computer games stores were much more fragmented so there was less of a chance to refurbish the shelves with them, unlike console games. Add also région availability, though the advantage of pc games was that they did not need region lock circumventing.
Some titles I tried. There are automatic installer versions for many.
