Betrayal at Krondor was the original DOS game and it is older than dirt compared to the other two, I know it was made prior to 1996.
RtK (1998) works absolutely perfectly on my system which is currently an Athlon XP 2600+. 1GB RAM, an ATI 8500 and onboard nforce sound, it is the newest of the three games.
BiA (1997) will run but I have the speed issue, I haven't bothered to try to test the color problem by dropping to 256 colors yet. I only have the color issue when it gets to night time in the game otherwise it's fine. I was able to slow the walking speed by changing the settting to small steps in the game and using Turbo.
According to the NT compatible website no one has ever successfully played BiA on an XP machine.
I have enough old systems here I could build an old 98 box just for that purpose.
Or since I am a system builder and have access to the MS Action Pack software I have some copies of MS Virtual PC, I was thinking of installing that and then installing 98 on the "new" machine it creates, that would let me play with this old stuff without wreaking havoc on my system which I use for work.
I have been playing RtK for the last couple of days, boy does that bring back memories, now if I could only find my manual so I can remember how to do things it would be a lot easier.
