In order to play these DOS games, you will need to be running DOS or a DOS emulator, such as DOSBox, which is available here. On that page you can also find downloads for a few other operating systems, which may or may not support your device. These will need to be run in a virtual machine or on actual hardware, probably by installing via floppy disk. I can't guarentee compatibility with any other software or hardware. It can get... complicated.
