I'm not new to PC emulators on the Mac as I've used at some point SoftWindows, Virtual PC (not the current version though), Bochs, and now iEmulator.

Configuration of iEmulator is about on par with earlier versions of Virtual PC (1.x), however, unlike Virtual PC it can have multiple emulated PCs running.

Now for the hardware that I have been using iEmulator on.

An old iMac DV/400 with 384 MB of RAM and MacOS X 10.3.9

On an older system such as this with no OPenGL acceleration, you have to uncheck the OPenGL rendering for the PC window to have it work.

Performance is not steller however, it does work quite well at what it is supposed to do. The OS I'm running on it is Win 98 SE with updates.

One thing that does annoy me however is that you can't run it in full screen mode as far as I can tell. There is one other thing that annoys me and I think it is connected to the fact that I'm using a machine that doesn't have OpenGL acceleration, namely that having Zoom (MacOS X's magnification software) on seems to not show the cursor in the PC window when Zoom is active.

Despite these minor setbacks iEmulator is a good buy at the price and I expect that it will get better as some prior issues I had with the emulator have been fixed.

Don't take my word for it though, shop around yourself and look at other emulators.

On a side note, iEmulator is way easier to configure than Bochs :-/

Note: I'm a hard person to please so, my ratings are a bit lower than some here however, I feel they are fair.
