I can see this artifact, but only on my Harmony and Harmony Encore. The ROM displays differently (please see below) via the UnoCart.

Thomas Jentzsch #77 Posted June 20, 2020 No, you assumed right the first time. We are looking for the pixel in the game square. Quote Share this post Link to post Share on other sites

Okay, then I stand by my original statement. The pixels in the game square were fine. Sorry for the fuzzy pics. Quote Share this post Link to post Share on other sites

alex_79 #81 Posted June 21, 2020 late PAL Jr. console (1991): and with the test rom by Spiceware posted in this thread: https://atariage.com/forums/topic/298427-weirdest-bug-you-ever-had/?do=findComment&comment=4394131 Back to "Space Invaders"... I tested all 3 versions on that same console with Harmony cart (doubled up v. 0.1 and 0.2 to 8k and added extension "F8S"). They work, but what's up with those stripes (playfield, I guess) on the background? They don't appear in Stella. Moreover, shots are gray instead of the sprite color (green on Stella, blue on my hardware because of PAL colors). Those stripes are visible also in alfredtdk's screenshots posted earlier. The score starts on the very first visible line on my TV, but it's fully visible. 1 Quote Share this post Link to post Share on other sites

Right difficulty switch, for debugging reasons. I started this project with z26, which didn't have the excellent debugger of Stella. 1 Quote Share this post Link to post Share on other sites
alex_79 #83 Posted June 21, 2020 I played a bit. It's looking great so far Sometimes the last invader gets stuck (but you can shoot him and continue playing). savestates.zip Quote Share this post Link to post Share on other sites
Thomas Jentzsch #84 Posted June 21, 2020 Yup, there was a bug when the last invader wasn't one from the top row. Quote Share this post Link to post Share on other sites
Thomas Jentzsch #85 Posted June 22, 2020 BTW: Can you post a few more Screenshots from the game screen with different patterns? Quote Share this post Link to post Share on other sites
Thomas Jentzsch #87 Posted June 22, 2020 Thanks. The line is always brighter than the rest. Quote Share this post Link to post Share on other sites
alex_79 #88 Posted June 22, 2020 I just noticed that you can disable the flickering with the left difficulty switch... 1 Quote Share this post Link to post Share on other sites
Thomas Jentzsch #89 Posted June 22, 2020 Didn't know that too. But the line is still there... Quote Share this post Link to post Share on other sites

If you can see it (partially, complete, on/off...), please take a picture or video (and maybe add a brief description) of the game screen where the color artifact should be most obvious. Also please tell us your hardware setup. Thanks! BTW: If your system has no color artifact, we don't need a picture. I see the artifact on my 2800 (NTSC, of course). This system has rev. D of the UAV mod installed. It also shows up during gameplay. 1 Quote Share this post Link to post Share on other sites
