I was poking around the wonderful collections on archive.org a few days ago, and stumbled upon an old DOS game that my son used to enjoy back in our Dos 3.2 days.
So how do you play such an old game? Easy, just head over to your Software Manager and install DOSBox!
Once you open DOSBox, use the built in tutorial to help guide you through how to mount a local file folder as a C:\ volume that old DOS games require.
After that, just navigate to the directory where your DOS games are stored, and launch the program by typing the name, just like the old days.
So dig out your old game CDs or find your favorite shareware games on-line, and enjoy!
