How to start the emulator in Emulator guide

A single PC can have multiple Symbian OS kits installed, each with a set of emulators. To run the chosen emulator, the following two command-line tools are used:

devices:To choose one of the installed kits to use. For more information, see Kit management.
epoc: To run an emulator from the current kit. By default, this starts the winscw debug emulator. A different emulator can be chosen by specifying one or both of the flags; -wins that specifies a WINS emulator, and -rel that specifies a release emulator. See also Emulator launcher syntax.

The following are many other ways of starting an emulator:

by running the project being developed directly from the IDE.
by opening the appropriate emulator executable (epoc.exe) in Windows.
by running a text console program implemented as a .exe. The code to create an emulator console window is built into such programs so that they can be started by simply running their exe file from Windows. By default, the GUI is also started, so that you will have to use the GUI shell to navigate to the running console program. A console program can be started without the GUI being started, by specifying the option -dtextshell -- on the command line, or by adding the statement textshell to the beginning of the \epoc32\data\epoc.ini file.
