Cobra Kai Posted August 9, 2005 Share Posted August 9, 2005 I picked up Pitfall and Pitfall 2 at a used game dealer awhile back, and never bothered to play test them because I didn't feel like hooking up my 5200, plus I didn't think Pitfall would work on my 2-port. Well, low and behold last night I hooked up the old rig and Pitfall works fine in my 2-port thats never had any bios work done to it. So what gives, is the Pitfall incompatibility issue a myth or do only some models of 2-port work?(obviously) Quote Link to comment Share on other sites More sharing options...
walter_J64bit Posted August 9, 2005 Share Posted August 9, 2005 (edited) I've read that but I think it's odd that it won't run on the 2 port 5200 is known why it won't run on the 2 port 5200? Edited August 9, 2005 by walter_J64bit Quote Link to comment Share on other sites More sharing options...
+FujiSkunk Posted August 9, 2005 Share Posted August 9, 2005 My Pitfall cartridge won't work on my 2-port 5200, so it's not just a myth. As for why, hopefully one of the more technical-minded will speak up. Quote Link to comment Share on other sites More sharing options...

As for why, hopefully one of the more technical-minded will speak up. 907206[/snapback] Is that what he was asking? As I recall, the reason is the 2-port BIOS added some NTSC/PAL code for a planned european release of the 5200. This shifted some BIOS fuctions around a bit. IF I recall, there's a "table of contents" that you can call to get at BIOS routines. Most games use this. Pitfall goes straight to the BIOS routines instead of hitting the index table. Which means it jumps to the wrong routhines because the PAL code moved everything. Quote Link to comment Share on other sites More sharing options...
+Mitch Posted August 9, 2005 Share Posted August 9, 2005 Pitfall and a couple others are incompatible with the revised BIOS that was in most 2ports. A few 2ports have the original BIOS and play those games just fine. Mitch Quote Link to comment Share on other sites More sharing options...
Zwackery Posted August 9, 2005 Share Posted August 9, 2005 Thanks Mitch! Is there some way (markings on outside of unit or inside somewhere) we can tell about the BIOS revision? I ask because because I have no problem with Pitfall in my 2-port (just lucky when I picked it up, I guess). Quote Link to comment Share on other sites More sharing options...

Hmm, you might be able to tell with one of the revs of the diagnostic cart as well. Mitch Quote Link to comment Share on other sites More sharing options...

No really, thanks for answering my question. Thats pretty much what I wanted to know. Quote Link to comment Share on other sites More sharing options...

Lord Thag Posted August 9, 2005 Share Posted August 9, 2005 My two port plays 'em fine too. Guess I'm a lucky guy! Quote Link to comment Share on other sites More sharing options...
jsoper Posted August 9, 2005 Share Posted August 9, 2005 I bought a big 5200 lot one time mainly for Meteorites (which I have on ebay right now btw). But it also came with a shiny new two-port and FOUR nice looking copies of Pitfall. I kept getting the image of this guy buying one new cart after another trying to get one that worked Quote Link to comment Share on other sites More sharing options...
HP Atari King of Michigan Posted September 10, 2005 Share Posted September 10, 2005 Whne I bought my 5200, which just so happens to be a 2-port, it came with six carts, including Pitfall. I tried to fire it up and it wouldn't work. I think it's safe to say I have one of the 5200's that don't play Pitfall. Quote Link to comment Share on other sites More sharing options...

Mitch 907230[/snapback] I'm about 90% sure that the later release Pitfall carts (the ones that BREGames was selling new for a while) work fine on all 2 ports. I've never had compatability issues with my cart on any 2 port and it seems very unlikely that every 2 port I have was already modded.

Then we would be able to verify if it's different then the standard one. Mitch Quote Link to comment Share on other sites More sharing options...

shadow460 Posted September 10, 2005 Share Posted September 10, 2005 See, I'm that way with my ProSystem--it plays everything and it's not supposed to. I'm going to have to look hard for a BIOS editor or a 4 port I can mod for a standard power pack when I buy a 5200. Quote Link to comment Share on other sites More sharing options...

Unfortunately, Activision carts have the screws under the label. Or I could send you a known 2port BIOS to put in one of your 5200s to verify that it indeed does work with a 2port BIOS first. That way we wouldn't ruin the label. I could also test it here I suppose. Mitch Quote Link to comment Share on other sites More sharing options...
