Glitchy horizontal lines in Vanish's "Monoxide" demo plus list of older reports
I get these glitchy horizontal lines in Vanish's "Monoxide" demo when CE is on. The CRC32 for the ADF is 0F8F6A59, though happens with pouet's DMS as well. 1. Disabling CE prevents the lines from appearing. 2. Happens with the latest beta as well, and there's even more lines. 3. For some reason, loading the attached savestate (recorded with 1.6.1) with the latest beta when CE is off, causes the demo to freeze and display a guru meditation error. Yet another reason to always use CE ========= On a completely unrelated note, from now on and for as long as necessary, I'll be reporting these type of gfx abnormalities on this thread so to make it easy to keep track of them. Here's the 4 unresolved ones from the Beta thread: Rolling Ronny (A500) Revelations (A500) SILICONE-Aspartame (A500) Nexus7 (A1200) Cheers. Last edited by Maren; 03 March 2010 at 20:13. |

Ok. This one looked so much like those damaged disk artifacts that I actually went through the pain of writing the adf to a real floppy so to be able to test it on my A500 and discard said possibility; unfortunately everything worked perfectly. Disabling CE doesn't help and happens with the latest beta as well. Last edited by Maren; 03 March 2010 at 20:13. |

Yes, I know I shouldn't do last minute changes but TechnoSoundCD and Monoxide are fixed

As usual, I can't tell if these glitches are related to WinUAE emulation whatsoever, in fact, disabling CE doesn't help in any of the cases so it could very well be something meant to happen on real Amiga hardware, given that it's mostly garbage frames flashing during scene transitions. It's worth noting that the glitches are also present in the latest beta 2.0.1.
The attached zips contain the bootlogs and respective savestates. Disks used: Kefrens Megademo 8 (1990)(Kefrens)[a](Disk 1 of 2).adf (CRC32: D49227D6) Kefrens Megademo 8 (1990)(Kefrens)[a](Disk 2 of 2).adf (CRC32: 02C5F790) "Gridder" (flashes when the scene starts) "Hide Away" (case 1, flashes when the scene starts) "Vector Maniac" (flashes when you left-click to quit the demo) "Hide Away" (case 2, flashes when you left-click to quit the demo) "Snake Bite" (case 1, flashes when the scene starts and it's probably just the image positioning itself) "Snake Bite" (case 2, happens when you left-click to quit the demo. The image reappears briefly and incorrectly positioned right before the demo ends) That's pretty much it. Regards. Last edited by Maren; 03 March 2010 at 20:13. |

These two are from a trackmo called "Burning Spear" by Dark Demon. The CRC32 for the disk used to record the savestates is F86B7066, but exactly the same happens with other disks.
Disabling CE doesn't help and happens with beta 2.0.1 as well. Both the bootlogs and the savestates are contained in the zips. First glitch; pretty much nothing to see here. Flashes as the scene with the blue spaceship starts. Second glitch; notice the garbled vertical magenta lines in the background. These are rather static and remain there for pretty much all the subsequent routines, shifting colours depending on what else's going on the screen. Last edited by Maren; 03 March 2010 at 20:14. |

This is demo bug. Needs ECS Agnus. (A500 confirmed long time ago..)

Enabling ECS definitely gets rid of the glitch, so I still don't get how it's a demo bug instead of just a wrong setting (I was using OCS while it required ECS)

Because there is nothing that requires ECS, just bogus sprite position data (that works accidentally if ECS)

Here's a minor glitch in "Megademo 2" by 2001 Datakill. Notice the garbage on the top of the fourth sphere from left to right. Works correctly with CE off, happens with the latest beta as well and the CRC32 for the adf is 6ADDF205 Download the 7zip containing the log files, the config and the savestate from here |

Thanks a lot for looking into these Last one completely fooled me because the glitch didn't happen with CE off.

This is a garbage frame from "Enigma 2" by Anal Intruders. I actually have vague memories of this also occurring on the Amiga where I first watched it, but vague memories are exactly that, vague. Disabling CE, increasing memory, switching to ECS, etc, nothing helped. Happens with the latest beta as well. The CRC32 for the adf is CB48CF8F. Log files, savestate and config can be downloaded in a single 7zip from the link below. http://www.fileshost.com/download.php?id=342F25611 Cheers. |

No real A500 test (yet?) but having 1 external floppy drive enabled "fixes" the problem.
