Microemulator can be made to have a large display, you have to set it in Options -> Select Device. Change the default to "Resizable Device".

EDIT: I can't get either qando.jar or qandoTouch.jar to open in MicroEmulator. It says "loading" but in the terminal, it gets an error ("java.lang.IllegalArgumentException: Malformed \uxxxx encoding")...

EDIT-EDIT: You can use "qando light" but it really is awful. This is probably what fred123 was talking about. It only uses a tiny corner of the display and no graphics to speak of.
