Man, this program is really cool. It allows me to install Windows98SE within WinXP in an emulation settings that allows me to run programs that will otherwise not run on WinXP. A good example of a software that is not supported fully on WinXP is No One Lives Forever 1. Although the actual game works, there are numerous issues with sounds and speech pacing. So, I installed VMWare in WinXP and loaded Win98SE within WinXP. Now, all those old and incompatible games (to XP, that is) work beautifully. This program is definitely awesome!! In fact, I'm typing this in Win98SE in emulation mode and the speed is the same!!
