Yeah, the picture there is still the same.

p.s.
Do you maybe (or anyone else) have info about other "Not 'emulation bug' Demos" from the 1st page that are now fixed/repaired ?! (please report here if found any)

There are some demos in first post, where a bad dump is reason for corruption.
Meanwhile you can take current TOSEC release as reference.

Note: Below demo has recently been added in Kestra BitWorld Demobase!

Roadrunner (Demo) by Copperteam -> http://janeway.exotica.org.uk/release.php?id=71362

A500 OCS (most common) -> some 3 strange dashes visible in overscan (but also not in Fullscreen(TV) if filter is enabled)


p.s. nothing important, mention it here (as well as all previous) in case if you would wanted to check it on an real Amiga!

(Probably usual overscan bug!)
Cheers

Yes. Demo has too small horizontal display window start value, not visible on most normal TVs.

[amilo3438]

Another recently added demo -> KS1.3 adf version ...

Megademo (Demo) by Ivory -> http://janeway.exotica.org.uk/release.php?id=866

A500 OCS (most common) -> some glitches on KS1.3 adf version (see on pic.) !!! (it doesnt happen on dms version in KS1.2)

(hmm, perhaps bad/damaged KS1.3 demo version or something else ... ?!)

A500 confirmed (better late than never), probably some bug, all parts are packed, even single bit disk error would break it completely.

dms version crashes on 1.3 because it patches exec with direct rom addresses.. (1.3 compatible version has totally different bootblock and loader code)

000015F6 2279 0000 0004           MOVEA.L $00000004,A1
000015FC 43e9 0238                LEA.L (A1, $0238),A1
00001600 32bc 4ef9                MOVE.W #$4ef9,(A1)
00001604 237c 00fc 12fc 0002      MOVE.L #$00fc12fc,(A1, $0002)
0000160C 2c79 0000 0004           MOVEA.L $00000004,A6
00001612 2d49 0094                MOVE.L A1,(A6, $0094)

And now some pre-emptive not 2.8.0+ bug information about Batman Vuelve / Batman Group.

Image at the very beginning of demo that shows batman for the first time has buggy cape graphics if OCS Agnus (note that it gets fixed when lightning strikes). This worked (incorrectly) without corruption in 2.7.0 and earlier. Correct behavior is broken graphics if OCS. Works if ECS.

There are also 2 other small glitches that are not emulation problems:

Following parts that have dot and line tunnels have darker area at the bottom of display.

Later part with running animal projected on a white vector cube has single frame that shows broken fill pattern on top part of cube.

A500 OCS and A500 ECS 100% confirmed.

Maybe pictures speaks more than words !!!

Batman Vuelve (Trackmo) by Batman Group -> http://janeway.exotica.org.uk/release.php?id=4262

On above link it said -> Released: 1995-07-23 ! (thus perhaps it is not supposed to work correctly in OCS)

But yeah, it is good to know that now it behaves correct in OCS too.

EDIT:
It looks to be fixed in test WinUAE 2710 beta4 (2014.01.25.) ...

perhaps below quote fixed it -> http://eab.abime.net/showpost.php?p=935948&postcount=40

- OCS Agnus requires one cycle between sprite DMA and bitplane DMA, ECS Agnus can have both cycles back to back. This means OCS Agnus will only fetch first sprite word (practically making sprite useless) where ECS Agnus can fetch both.

Obviously Complete left side of display (building + batman) is made from multiple tall sprites.

A500 OCS/ECS (most common) ... Mindriot / Andromeda demo is broken (see pic.) ... (2710b4 - last version where still works ok)

Cheers

[amilo3438]

A500 ECS (most common) ... Surrealism / Andromeda demo ... some glitches in marked area, see pic. below. (2710b3 - last version were it does not happen)

[Toni Wilen]

Should be finally really (and so on..) work correctly.. There was another undocumented side-effect that was not emulated which was the real cause for rindadink (original, not redux) extra pixel. Previous fix was simply wrong and broke other demos.

[amilo3438]

A500 (most common) ... CoderTrash / Mexx ... strange glitches on last part of demo; from generated 11 pictures only on four pictures are noticeable glitches ...
see on attached pics. below: (tested on 2710b6; didnt test older versions)

EDIT: Also, some glitch is present on 1st picture (see on pic. 6) !? (wonder how I missed it during last year's of massive testing demos )

[Toni Wilen]

I think you are again in wrong thread because it happens with 2.7.0 too

(and where is the glitch in image 3?) EDIT: just testing and it is exactly as in your screenshot.

EDIT2: A500 test done. Identical glitches confirmed in "cyclepics" part.

EDIT: this probably belongs to your big thread.

[amilo3438]

A500 (most common) ... Straight Outta Jörlanda / Insane

Red border (pic.1) ?!
also if ECS Denise then is black (pic.2) ... is that correct ?!

Yes and yes.

It enables borderblank option which is ECS Denise and AGA only.

For some reason it also has obvious border color gap in first line of image (COLOR0 change too late in copperlist).

[amilo3438]

Almost forgot on this ... Hifreaks / Supplex glitches again from 2710b8 (see on pic.) ... maybe not worth the trouble !

p.s. Hope, the fix will not broke something else ! (hope so, it should be really all)

Cheers

This is more interesting because I just watched first 5 minutes of this demo 3 times on my real A500 and 2 times there was a glitch, in different places. 3rd time didn't have glitches. I previously never watched it that far because "original" emulation glitch was at the very beginning and this demo is quite boring to watch..

First time glitch appearet when "write to" text was on screen and second time it was about 1min later.

So glitches are normal and this may not be a real bug, just the usual that emulation is designed not to be random at startup to make it possible to replicate exact same behavior with matching config + exact same version. (It is not designed to stay the same between versions)

EDIT: in other words: Nothing will be done.

Unable to get that to run under newest Winuae versions, tried all possible A500 ECS/OCS variants, but that one does not work.

Works fine with standard A500 CE config. (Make sure you wait, it may look like it exited. Just wait more..)

Also pre-emptive note: any kind of glitches you see are not emulation glitches, especially in plasma part.
