What is the current behavior?

Running build.bat with DoRun=1 without configuring the emulator path in default_config.cmd results in an obscure error message ( was unexpected at this time for newcommers.

This happens because setup_emulator.cmd checks if /I %EmulatorName%==openmsx, but when EmulatorName is empty it is replaced with if /I ==openmsx, hence the ( was unexpected at this time error message.

The script should check if EmulatorName is set beforehand and display a clear error message to the user.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

• Change DoRun=1 in projects/samples/build.bat
• Make sure to have the default set Emulator= configuration in default_config.cmd
• Open a command in projects/samples
• Run build.bat s_game
• The sample does not run and the script leaves you with ( was unexpected at this time

What is the expected behavior?

The script displays a clear error message of what happened.
