All my games for classic systems can be played using the original hardware, but that may be a bit difficult when we are talking about machines that are more than 30 years old.
Another good option to enjoy the games is by using an emulator on a modern machine.
There are more emulators, but these are the ones I recommend!

Although you can probably run DOS on modern hardware, you may not have a Sound Blaster!
