Mortal Combat, Street Fighter and Super Mario Bros. are the popular games of my time the 90's era. There's a lot to mention but these three games are the most played by kids before including me and my siblings using the Ninntendo console which is a perfect gaming console at that time and including SEGA as well. I guess I'm lucky to play those during my childhood.
If you have DOSBOX then you can still learn how to install and play those games. I have learned how to install the DOSBOX and also make use of the local folders for the usage of the gaming. I can tell you that gaming memories are not that much effective for me anymore as I tend to play a lot of games.
