To Greyface, upgrade for improvements and support. Other games require other tools that may or may not be supported in XP.

I have no game that does not run on Win7, including very old Dos ones. Actually the one with the most issues are the windows 3.1 or Win95 type.

Lucky that some come with a Dos execute version. I did have to resort to running 3.1 under Win7 for my old Stars! game.
