Above is a link to my Retro gaming links. I am not able to update my computer very often, so I play older games. I had to find and learn how to use utilities and engines that allow the playng of older games on newer operating systems.
The links contain alot of links to help run older games like doom, quake, wolf3d, sierra adventures and on and on.
Check it out.
Just scroll down at the link for the RGL.
