badbrad Posted May 1, 2006 Share Posted May 1, 2006 Why is it that this cart doesn't work on the 2-port system? Quote Link to comment Share on other sites More sharing options...
SteveW Posted May 1, 2006 Share Posted May 1, 2006 I believe it's the BIOS in the 2-port console being slightly incompatible. I just play the Atari 8-bit version. It's so much better with a digital joystick. Quote Link to comment Share on other sites More sharing options...
CPUWIZ Posted May 1, 2006 Share Posted May 1, 2006 Why is it that this cart doesn't work on the 2-port system? It's the 2 port BIOS, if you swap it for a 4 port BIOS, it works fine. Quote Link to comment Share on other sites More sharing options...
badbrad Posted May 2, 2006 Author Share Posted May 2, 2006 Is this just the matter of swapping a BIOS chip out? Is it worth the trouble for just this one game? Quote Link to comment Share on other sites More sharing options...
CPUWIZ Posted May 2, 2006 Share Posted May 2, 2006 Yes, simple swap, and it's not the only game that has problems. Quote Link to comment Share on other sites More sharing options...
jetset Posted May 2, 2006 Share Posted May 2, 2006 Is this just the matter of swapping a BIOS chip out? Is it worth the trouble for just this one game? I thought there were three games that didnt work on the 2-port? I seem to think one other was Mountain King and maybe Pitfall2 was the 3rd? Maybe I'm not remembering correctly. And I'm certainly too lazy to search. Quote Link to comment Share on other sites More sharing options...

badbrad Posted May 2, 2006 Author Share Posted May 2, 2006 I'm not really lazy, I was disassembling. Is the BIOS chip at location U8? Quote Link to comment Share on other sites More sharing options...

badbrad Posted May 2, 2006 Author Share Posted May 2, 2006 (edited) Yes, you can also burn the 4 port BIOS onto a 2532 EPROM. Cool. Thanks, R. I happen to have a dead 5200. That's what I was taking apart earlier. Too bad this info isn't in the 5200 FAQ. Edited May 2, 2006 by badbrad Quote Link to comment Share on other sites More sharing options...
Big Player Posted May 2, 2006 Share Posted May 2, 2006 So does Sean Kelly's 5200 Multi-Cart have hacked ROM's of Krazy Shoot Out? It appears to work on my 2-port but I only played it for a few minutes when I was going through all the games on the cart. What happens when you put the game in a 2-port? If I remember correctly, I had trouble leaving the room. Quote Link to comment Share on other sites More sharing options...

Zwackery Posted May 7, 2006 Share Posted May 7, 2006 I have 2 two ports that apparently have the 4 port BIOS because I've never had a problem playing any of the 5200 titles on them. Quote Link to comment Share on other sites More sharing options...
sku_u Posted May 7, 2006 Share Posted May 7, 2006 Some do. Look for a letter next to the serial number on the bottom. Quote Link to comment Share on other sites More sharing options...
