several updates and optimizations to fpga and simulation versions.
add input to fpga using onboard buttons, an attempt at audio via onboard audio but I think the filtering is wrong
add input switches to digital TTL simulation, add reset for easy start
some updates to my missle game gbas project, I'm cheating a tad and using the line routine for faster erase but my math isn't exactly the same
