@Amilo3438
Oops, this is one of my very old report ( 2018 ). it's CPU related as usual. Note : video of this demo in real hardware ( created during our tests on real A1200/WinUae on a French forum ). [ Show youtube player ] Last edited by Zarnal; 23 May 2021 at 14:34. |

At each power up memory chips has these different (in some cases very different) bit patterns, so the demo is visually different on each machine. Toni would be forced to define a bit-pattern and I don't know how much sense it makes, considering that they are quite random (even if they follow usually a 0/1 'chessboard') .. Into the Zone! a 'proper' version, using a memory 'chessboard bit-pattern' synthetic fix. For the interested this is how the patterns are made (d6=largest chip-mem available space): Code:
moveq #0,d0 moveq #-1,d1 divu.w #(2*48*5*8),d6 subq.w #1,d6 .3 moveq #2-1,d5 .2 moveq #48-1,d4 .1 moveq #5-1,d3 .0 move.l d0,(a0)+ move.l d1,(a0)+ dbra d3,.0 dbra d4,.1 exg d0,d1 dbra d5,.2 dbra d6,.3 Last edited by ross; 24 May 2021 at 00:00.

I have mentioned it few times previously that I won't add it until someone explains RAM chips internal layout because thats the important bit (or does dozens of experiments to find out the pattern). Same rows and/or columns seem to have same bit (mostly) at powerup which explains the "chessboard"-like pattern.

zarnal will understand...
http://eab.abime.net/showpost.php?p=...&postcount=783 it's just a temp quick and dirty graphic fix because unfortunately it's not a code bug. If a "final" version existed, it would be better |

@ross: by the way, thanks for the fix of Ubergirl.
yep, another "old" thread about it somewhere on this forum http://eab.abime.net/showthread.php?p=1420396 |

Finally got these two to work with no problems, by simply turning JIT off (cachesize=0) and using Fastest Possible, adjusting the sound buffer and also turning off Vsync too. I thought I'd tried it already, but turns out that wasn't the case. So now that's 0 demos that I need keys to control JIT for, meaning I can get rid of them. As for Fastest Possible, I wrote it off too soon, as it does come in useful for those demos that are too slow on Approximate A500/A1200 or Cycle Exact. Thanks for the help, Toni, and sorry for the inconvenience. Last edited by Foebane; 25 May 2021 at 12:30. |

Some checks were made on A1200 this weekend, some results are very "surprising".

WinUae beta 4.9 b31:
I noticed a new problem with the "Noxious-Beyond Relief" demo which seems to be related to the chipset. The background image is distorted sometimes on the beach scene (pic 1). Since b22. Quickstart A1200. Last edited by Zarnal; 20 November 2021 at 19:17. |

@Zarnal
Bug / glitch tracking WinUae / FPGA / A1200 stock So there is another place for bug tracking! (this information is on a need-to-know basis) Note: The point is not to fix a demo to work with the emulator but to fix the emulator to work with a demo! Btw. Polka Brothers-Twisted should work fine with KS3.1 on the emu - at least worked on an older versions A1200+4Mb. (and crashed with KS 3.0, if I remember correctly) EDIT: Tested to work on latest beta on A1200 basic CE (DMA/memory) enabled and KS3.0! Last edited by amilo3438; 01 September 2021 at 17:51. |

Benoit (Demo) by Ramses (found by my "counterpart" on AmigaFrance)
[A1200 basic] Got an message: Sorry ! This demo needs an A1200 68020 14 Mhz ! (JFI: There is an version on previous post fixed to work with the emu! ... still glitches!) Last edited by amilo3438; 01 September 2021 at 16:34. |

@amilo3438
This list is only valid with WinUae 4.1. It was the last version when I started. For the majority of issues of my list, these are CPU concerns. It is for this reason that I have not reported any bugs here. ( example: Ramses-Benoit patched version works fine in CPU fastest mode without black bars ). Another example: Union-Zoombi has unconfirmed glitches on a real stock machine, but on a real machine accelerated with an ACA 68030, the glitches are identical to those of WinUae. All problematic demos were tested on real stock hardware. With the new Agnus emulation, we got some demos in cycle mode (FD-Methylate, Passion-Alien inspiration, Passion-Comadose, PK-Planet M and some others). I will retest my entire list from A to Z after the official release of WinUae 4.9. Last edited by Zarnal; 01 September 2021 at 18:43. |

I don't know, I am slowly losing interest for AGA and 68020 because of all still unknown details needed for precise emulation. For now I stay focused on OCS/ECS machines.
Hmm, maybe better wait for WinUAE 5.x! (Toni somewhere mentioned something about new findings, so this could probably wait until all other thing is finished, I guess.) |

Toni, ignore my stupid report on the Noxious-Beyond Relief demo from today. After seeing the same kind of glitches in other demos, I realized that CE full chipset mode was disabled in Quickstart A1200 mode ( ( Why exactly ? i don't know really ). A regrettable inatention. Everything is now back to normal.
I will have to redo all my tests done today later. Quote:
