Believe it or not, Sundog can be played using your IBM PC!
The only difference in the game is that you cannot save games
(except for the one your playing).
This page used to explain how to set everything up but now someone has made it into one easy zip file to download!!
Go to the Underdogs site to download one .zip file with an emulator and Sundog!
The download link will be towards the bottom of the page.
NOTE: The page is still there but they do not have the download up for some reason. Hopefully they will bring it back soon.
