Hi again Denis. I have a quick question about this. Is there a 
special way in which I should compile the runtime? For me 
personally it didn't do much - from 2.8MB to 2.5MB.

Also, could you give more details about this? I have only found a 
few Cortex-M devices that could be emulated, but none of them had 
the resources I needed. The biggest was with 64KB of RAM and 
256KB of flash.

Thank you!
