Last weekend I was trying out the different versions of RA1 which are currently available.
My self modded hi-res (hifi) version of RA1 had some mouse cursor drawing problems on the new PC System.
-OpenRA 2013-05 - plays nicely for what it is, but too far from the original for me.
-OpenRA Classic RA - locks up sometimes, as already warned for. Still too far from the original anyways.
-Hifi DDraw.dll - Fixed my mouse cursor problem, that's nice, and runs fast enough on my new system.
-Arda project - Nice, but I had a little difficulty integrating it with my own adjustments.
-(Irans) Portable RA - This is excellent!, Love the new build bar +aspect ratio correction+ small soldier option: I'll definitely stick with this.
