i have search on Google that to run windows 8 emulator,CPU must be supporting SLAT. and my PC does not support it. so i am not able to run emulator. now in this case is there any other way to run emulator because purchasing windows mobile or new processor is not good idea. i dont have money for this. processor core 2 duo RAM 4 GB DDR2
While SLAT isn't required on Windows Server 2012 to enable HyperV, it is required for Windows 8+ to enable a rich graphical experience.
There are some details here.
If you're developing a WP8 application, I'd highly recommend you acquire a physical device anyway for the best overall development and testing experience. Depending on your location, there are some very inexpensive devices.
There are no work arounds.
