Does this program also support blueMSX? If so, is there a way to set it up as a emulator for MSX projects?

The build process for each machine is configurable, you simply need to edit a batch file to fire up a specific emulator

How do it edit the batch file?
Do I simply replace "openMSX" with the other one (like for example "blueMSX")?
