Jess Ragan Posted December 2, 2007 Share Posted December 2, 2007 Talk about an unexpected surprise! I recently received an Atari 5200 in a trade, to replace one that stopped working. On a whim, I decided to pop in my copy of Mountain King, even though this game generally doesn't work on two port systems. To my surprise, it ran perfectly... and now I'm starting to wonder why. Was this system shipped back to Atari for a replacement BIOS, or were there a few two port models that could run these games straight out of the box?

I did not even know there was a two port issue on this one. So there must have been a few Quote Link to comment Share on other sites More sharing options...
+Mitch Posted December 2, 2007 Share Posted December 2, 2007 Yes, there are some 2 ports out there that have the original BIOS from the factory instead of the the revised one. Looks like you guys lucked out. Mitch Quote Link to comment Share on other sites More sharing options...

Looks like you guys lucked out. Mitch Yes but the 2600 adapter will probably not work Actually, they're two different issues. The 4-port bios wasn't the problem with the 2600 adapter it was something on the 4-port motherboard. Quote Link to comment Share on other sites More sharing options...

Controller ports 3 and 4 have been eliminated, ... Three pins on the cartridge connector have changed to accommodate the new 2600 adapter.

Jess Ragan Posted December 2, 2007 Author Share Posted December 2, 2007 Sadly, my 2600 adapter won't work on anything. I'm not sure what's wrong with it, but my system won't power on with the adapter inserted. My last system did the same thing, and I'm not entirely sure why.
