Berzerk 7800+

another Great Atari gamekeep them coming Atari

This is such a iconic game and reminds me of my youth playing this. The robotic voices sounding just like Battlestar Galactica. Not as clear as the arcade or the new wave toys mini arcade version. Doesn't work on the 2600+ unless you down load the updated firmware, which was a bit of a chore but not that hard. It's definitely a step up from the 2600+ version and you can play two player co-op. Also it has the frenzy version if you press the right buttons.

Beware if you have a 2600+. A lot of the second wave of cartridges don't work even though they say they are compatible with the 2600+. The forums are full of complaints about them. Some people have managed to get certain titles to load by doing an update (which is quite a faff if you are non-technical). Some report certain carts still don't work even then. Mine is going back like many others from the sound of it.
