alfredtdk Posted April 27, 2021 Share Posted April 27, 2021 The random change of the color palette in some games of the atari when they were static, especially those of Activision, in the current games or homebrews, as they are defined today, I no longer see being used. It is obvious that with the evolution of modern TV this feature that was once used to prevent the stain tube of the static image is no longer necessary. But in my opinion that was one of the charms of the atari games. I always wondered if there was a way to activate these changes in the color palette and select one of them from a kind of menu created within the game to eventually play in the changed colors. 7 Quote Link to comment Share on other sites More sharing options...
glurk Posted April 27, 2021 Share Posted April 27, 2021 That is called "attract mode" and it's built into the 2600 itself. Almost every game will do that, if it is not intentionally disabled. It's in the Atari 8-bit computers too, though often disabled there for certain reasons. Since it's not a feature of the "game" per se, it's not possible to play that way, unless you hack the ROM and change the palette inside it. 4 Quote Link to comment Share on other sites More sharing options...

It's not totally obsolete. Some display technologies are still susceptible to burn-in. I notice modern consoles like the Switch will dim the picture after some inactivity. 5 Quote Link to comment Share on other sites More sharing options...

The old one sits turned off most of the time, but you can see the burned-in icons that I had on the home screen for years 3 Quote Link to comment Share on other sites More sharing options...

AFAIK it's not built into the 2600, it was in the games themselves, similar to how the color/bw switch has no hardwired function, the palette change is part of the game program. 4 1 Quote Link to comment Share on other sites More sharing options...

It would be necessary to create a menu, similar to what Omegamatrix has been doing with some classic games (Warlord, Combat, Outlawn), but in this case it would be to choose one of the static scenarios.

LCD can have temporary burn-in issues where an image will ghost, but will resolve itself over time or when the TV is restarted. I have one TV that has this issue, but haven't seen it on other LCD TVs or monitors. 4 Quote Link to comment Share on other sites More sharing options...
joeatari1 Posted April 27, 2021 Share Posted April 27, 2021 Older plasma TVs can have burn in too. My basement TV is a 55" Samsung plasma and I am very careful not to keep the screen static for too long. I don't think anyone makes plasma TVs anymore (I believe due to high power consumption), so I'll be keeping that one for as long as I can. 4 Quote Link to comment Share on other sites More sharing options...

A bright white 3" wide bar rolls across the screen for 10 to 15 minutes. Had to use it a couple times - leaving the tv on SVU with the TNT logo on the bottom for 6 hours a day really does leave a mark. 3 Quote Link to comment Share on other sites More sharing options...

I think it was the fact that OLED TVs were on the way, and they have the deep blacks that you used to need a plasma for. Plus OLED screens are much lighter and use much less power. 1 Quote Link to comment Share on other sites More sharing options...

You see how a child's mindset works, I really thought that by making a combination of the Atari keys I would be able to access secret game menus or activate any of those static screens.

The cheaper ones had about 30,000 hours of use, and the upper ones about 60,000, before hitting that 50% loss threshold. 1 Quote Link to comment Share on other sites More sharing options...

It's certainly built into the Atari 8bit. You can leave a screen sitting on the READY in basic, and it'll start to do it. The early equivalent of a screen saver.

Harry_Dodgson Posted June 8, 2021 Share Posted June 8, 2021 It's not a hardware thing - it is definitely in the software. The programming guide specifically mentions it. 2600 games had the foreground/background color changes in all games cartridges that did it. With more memory, came better attract screens like demos and high scores. Quote Link to comment Share on other sites More sharing options...

With more memory, came better attract screens like demos and high scores. Software on both machines. The Atari 8-bit computer OS runs a routine in the vertical blank interrupt which checks for keyboard presses. If none happen in roughly 7 minutes, the brightness is dropped and random colours are chosen. This feature was definitely taken from 2600 software, which did it first (obviously per game, as there is no OS on that device). Quote Link to comment Share on other sites More sharing options...

So is it a function built into the OS, and hence something that needs to be disabled in software, or is it something that just happens to be included in BASIC as well (and hence it wouldn't work on say the 400/800's memopad?) Always sort of wondered about that. I don't think I ever saw it on the 2600 as we wouldn't let that thing alone fir more than 7 minutes. ?

To see this, you can for example, boot into DOS with the cart disabled and wait the appropriate time and it will still kick in. Quote Link to comment Share on other sites More sharing options...
