To run the Conquest of the New World game get the freeware program DOSBox. I use the command line C:\Games\DOSBOX\dosbox.exe c:\games\newworld\cnwmain.exe -c "mount d d:\ -t cdrom"
The only problem is you need a rather powerful microprocessor, I have an Athlon 2200+ and the game still runs kind of slow. Also repeatly use the command ctrl+F12 in the program to increase the speed of DOSbox to the maximum your microprocessor can handle. My processor maxs out at 15,000 CPU cycles. Use sysmon.exe(kernel processor usage) which is in the windows directory to determine how many CPU cycles you can handle.
