Tempest Posted January 14, 2020 Share Posted January 14, 2020 I saw something similar in Skydiver where the bottom part of one of the plane wings (the green one?) was glitched like that. Quote Link to comment Share on other sites More sharing options...

Kiwi Posted January 14, 2020 Share Posted January 14, 2020 That's probably when the 0 get loaded into GRP1. The kernel would have to do comparisons when to load the value into the GRP0 GRP1 ENAM0 ENAM1 ENABL. There's not enough time to check all 5 comparisons on 1 scan line. It looks to me it is double line kernel. So the value 0 was loaded where the glitch is. 1 Quote Link to comment Share on other sites More sharing options...
+SpiceWare Posted January 18, 2020 Share Posted January 18, 2020 It's called shearing, it can occur when a TIA register is updated during the visible part of the scanline. I cover it in Step 4 of my Collect Tutorial. Another good example of it is the right side of the background gradient of Air-Sea-Battle. 2 Quote Link to comment Share on other sites More sharing options...
