Is there any way to get Java apps for the N97 (like the qandoTouch.jar app) to work on the N900? What do they require to work?

What exactly is the Nokia Java Runtime for S60v5? Is it an extended version of ME? A pared -down version of SE? I'm guessing the former, because Java SE doesn't run the .jar files either...

I think MicroEmulator is only designed to handle the really simple JaveME apps (.jad files) and the JME files packaged as .jar are too much for it to handle.
