vectormatt Posted September 16, 2021 Share Posted September 16, 2021 I recently recapped my O2 and voice module and installed the RGB mod. I’m playing some games through a Sony PVM 1415. The picture is absolutely phenomenal. The photos can’t do it justice. The one thing I do notice on some games though, particularly fast moving games, is some small red sparkles on parts of the screen. Is that something normal with the Odyssey or possibly a ram issue? They are pretty tiny, like static, the color is always red and they only happen on fast moving games.

vectormatt Posted September 20, 2021 Author Share Posted September 20, 2021 I noticed a different RGB/YPbPr mod on eBay with some screenshots. Each of his has a little red sparkle in it too. Just one in each picture that I can see RGB/YPbPr Video Kit for Magnavox Odyssey 2 | eBay I'm wondering if maybe my red output just needs a little capacitor. I can experiment.

R.Cade Posted September 21, 2021 Share Posted September 21, 2021 (edited) You can try, but that looks like digital distortion, so filtering the output won't likely help. You are right, those dots are in the screenshots of the device for sale also, so it appears inherent to it.

vectormatt Posted September 21, 2021 Author Share Posted September 21, 2021 I’ve also noticed that games like K.C. Munchkin and UFO! have those sparkly dots across the top of the screen. On other games like K.C.’s Krazy Chase! and Attack of the Timelord they appear towards the middle/bottom. Definitely seems more like a digital issue. Caps probably wouldn’t help much as you say, but I may try anyway for giggles on the red output. I can also try testing the ram and other components. It’s definitely not bad enough to ruin the fun of playing the games though.Sent from my iPhone using Tapatalk Pro Quote Link to comment Share on other sites More sharing options...
+grips03 Posted September 22, 2021 Share Posted September 22, 2021 This is due to how game is programmed. Nothing to do with mod. Rene fixed several games that do this. It was discussed in the past here and on videopac.nl Quote Link to comment Share on other sites More sharing options...
+grips03 Posted September 22, 2021 Share Posted September 22, 2021 Here is that write up: Q. When playing O2 games using RGB I notice small flashing dots on screen in different spots based on the game being played. Example: K.C. Krazy Chase = small red flashing dots in the lower / center part of TV screen. UFO and K.C. Munchkin = small red flashing dots at the top of the screen Mage the Final Journey = small red flashing dots at the left of the screen Any ideas of the cause? A. Yes, this is caused by changing the background color mid-screen. With a normal RF connection the dots are too small to notice, but with an RGB connection they are clearly visible. What happens is that when data is loaded into VDC register A3, the write pulse occurs too soon, before the data is available on the data bus. At that moment the databus still contains the address (A3), so that is used as background color briefly before the actual data (color) is written to register A3.

R.Cade Posted September 22, 2021 Share Posted September 22, 2021 From that thread, it sounds like the games could be patched/fixed to get rid of them. It would probably be a lot of work. Quote Link to comment Share on other sites More sharing options...
vectormatt Posted September 22, 2021 Author Share Posted September 22, 2021 Thanks for the clarification. Now I don't have to wonder if there's some issue I need to troubleshoot. I guess that's the drawback of having an absolutely perfect video signal. LOL Quote Link to comment Share on other sites More sharing options...
