It uses Tosca TBox for steering Host controls via emulators. For a list of supported emulators, see the system requirements.

Emulator recognition

The HOST Engine 3.0 can automatically recognize the type of your HOST emulator based on the specific .DLL file located in your system. There is no need for additional setup.
