EpikalPuppy Posted December 3, 2019 Share Posted December 3, 2019 I recently got my first 5200, and, as the case on it was cracked, ordered another that was "untested". The untested 5200 actually came with some games: Moon Patrol, Galaxian, Ms. Pacman, and Space Invaders. I already had a few games: Qix, Pacman, Super Breakout, Soccer, Baseball, and Centipede. When I put Moon Patrol and Galaxian in the 5200 I already owned, they both had weird glitches. Moon Patrol would have weird colors, purple on the title screen, and the rover was green instead of purple. Galaxian had random lines on the screen and would not start. Every other game I had worked perfectly on this system. When I tested these games on the untested 5200 that I had just gotten, they worked perfectly. I tried reseating all of the chips on the board of the original 5200, but the games still don't work correctly. If anybody recognizes these symptoms and could help me with this, I would greatly appreciate it. Quote Link to comment Share on other sites More sharing options...
0078265317 Posted December 3, 2019 Share Posted December 3, 2019 Mountain King Pitfall 1 not 2 K-crazy Shoot-out Are know not to work on 2 port systems. The rest should be fine. it's weird they are not. There is a color pot adjustment wheel inside the 5200 you can try adjusting. Quote Link to comment Share on other sites More sharing options...
Greg2600 Posted December 3, 2019 Share Posted December 3, 2019 Technically you could swap in a bios chip from a 4-port and get compatibility. Otherwise if you had an Atarimax flash cart, there are hacked versions of those games which do work on 2-ports. 2 Quote Link to comment Share on other sites More sharing options...
EpikalPuppy Posted December 3, 2019 Author Share Posted December 3, 2019 (edited) Well, these games work on one of my two ports, and don't work on the other. They are also not four port exclusive games, also, it's not just the colors that are wrong, Galaxian crashes at the title screen. Is there anything special about these games?

SoundGammon Posted December 3, 2019 Share Posted December 3, 2019 I have a custom 4-port OS chip that changes the text / font to a computer style that I can make you a copy and put in yours! Quote Link to comment Share on other sites More sharing options...

What does the computer font look like? I've actually never used an Atari 8-bit, but I really want to get an 800 or 800XL. Quote Link to comment Share on other sites More sharing options...

Greg2600 Posted December 4, 2019 Share Posted December 4, 2019 Just now, cjherr said: Thank you. Another option is just get a "4-port" bios and slot that in.

Sounds like something else (dirty or faulty). I definitely agree that something is faulty. I cleaned the cartridge connector with a toothbrush and IPS, and same with the carts. They work on my other two port just fine. Quote Link to comment Share on other sites More sharing options...

It was simply made because I DO happen to have all 3 hacks (one for each game) and I was about to (at the time) bring that up, and maybe share with fellow 2-port 5200 owners with Atarimax Multicarts so they can play those three great titles too. ...and, yes, just now I read the quoted yes his problem was not related, thanks.

0078265317 Posted December 11, 2019 Share Posted December 11, 2019 (edited) So I found a cheap copy of Pitfall 1 with box. One of the three that is not supposed to work. Did not boot in my 2 port. So what exactly is supposed to happen? Mine is just black screen. No audio or video. Is that how its supposed to be? Or does it boot and then glitches while playing? Or hangs while trying to boot? Shouldn't I at least get the atari logo trying to load? Edited December 11, 2019 by 0078265317 Quote Link to comment Share on other sites More sharing options...

baktra Posted January 12 Share Posted January 12 (edited) Is there an image of the 2-port BIOS ROM somewhere? I have been looking for a while, but all I found is the BIOS ROM for the 4-port models. Edited January 12 by baktra Quote Link to comment Share on other sites More sharing options...
