I 've just discovered this Gem on the 2011 Denial disk. (By Robert Hurst. Thread discussing its development here . Game available here .) I love Berzerk and this is a very good-looking and very playable version. The software sprites move quickly and smoothly and the sound effects are just right. What could be better than that? Well the MMX+ version has synthesised speech! Yes, sound samples of the menacing robotic "Intruder alert" type sounds as featured on the arcade game. Coming from a Vic chip. That's blowing my mind.
