I was wondering if there was a way to make two games run in windowed mode. Also which codec should I be using for best performance, ie Direct3D, OpenGL etc. Thanks.

Well I thought I might as well reply here for others since I finally found some info. Going by what others say these are the best settings. Go into the config file of every game you want edited and change these to display-

fullscreen=false
fulldouble=true
fullresolution=original
windowresolution=1024x768
output=ddraw

The window res makes it larger then the default tiny screen. Everythings working pretty good with ddraw and that res. Obviously you could make it larger but I like the size for now.
