Analog Devices provides a C/C++ compiler and a RTOS for SHARC, so I wouldn't be surprised if nethack could be compiled for the SHARC VLIW architecture (and its two branch delay slots).
well I stand corrected, it looks like there's even a fopen and fprintf in there so that would make a lot of things possible. I wonder about the performance for branch-heavy, non-vector-math computations on these CPUs.
