I got a stack of floppies with the set and I noticed one game in particular: Nibbler. I don't remember seeing it BITD but I noticed now because of the recent attention for the arcade version. Sure enough it shows Rock-ola as the original maker and although I never played the original it is a very fun and challenging game

they improved one part of the game: they left out the terrible music of the original

I also just had a quick go at Berzerk on the NTSC machine and man, how close can a conversion be ? If you can't get a Berzerk cab, get this and you are 99% playing the real thing...incl.the voice.
