The new devices use custom ASICs and that is why the newer code cannot be emulated. The reality is that they have 2 types of codes 1. Platform Independent code (PI) (which could have been used to support GNS3 if they wanted) 2. Platform dependent code. (Of course this is for custom ASICs) Since Cisco saw the opportunity to launch VIRL (commercialized and based on Platform Independent code), they decided not to support GNS3... So GNS3 team must find something to stay there ...
