I'll try to continue with 68020 timing improvements later this summer. Maybe.. Only 68020 CE mode and CD32 MPEG emulation remaining...

FYI, a list of AGA demos with potential small problems when running in current WinUAE A1200 CE mode:

(forgot what was the problem for each demo, so for now there is only a list)

Disaster-PEASOUP.LHA -> Pea Soup / Disaster
EVACUE-Nil -> Nil / Evacue
ModelDesign_-_NeoTokyo2094_(0494_AgA).ADF -> Neo Tokyo 2094 / Model Design
Oxygene-Cuzco -> Cuzco / Oxygene
Passion-AlienDream -> Alien Dream / Passion
SAINTS-DestinationBBS -> Destination BBS Intro / Saints
TBL-PHCK.EXE -> Phucker / The Black Lotus

EDIT: In adition...
The Saturne Day / Apex

yes please, more aga demos compatibility would be very much appreciated :D

After checking each one in quickly warp mode, I only see obvious problem in first demo, others appears to only have usual overscan bugs and inaccurate 3d-calculations.

Of course, if the same happens on a real Amiga then no problem !!! :) (see some examples below)

@amilo3438, can I just say a huge thank you, I had a nag at you early on but you have stuck to your guns and bug tested so many demo's resulting in WinUAE being better and better.

You truly deserve a mention in the help files as a credit.....Hugely deserved...

I'm not sure about that, I do not fix problems, rather than just finding and inform ... so there's no need for that.

But in any case is comfortable when you hear that someone from users recognize your efforts, so thank you very much for that.

Sooner or later progress would occurred, the difference is just that I did not have the patience to wait anymore to happen. ;)

Well at first I thought you were being too cocky but you have sat down and done something that is both time consuming and incredibly boring and tested hundreds of games and trust me I do know what that's like. Its ok for the first few and then the constant repetition turns to boredom, its very hard to convince yourself to carry on.

But you did and do deserve that credit..

By identifying emulation bugs you have helped Toni improve WinUAE a LOT, sure he does the technical bit but only because you did the hard work of finding the issues.

Well done and thank you to you both for making Winuae even better...

But one correction, I did not tested hundreds of games (I do not care a lot about games), only demos (>12000, or more, I stopped to count) ... but of course, if demos works fine then games should work fine also. :)

Yeah, more or less, thanks again on kind words.

p.s.
Just one note: I am not done it for the sake of fame ... just a pure pleasure! (the glory belongs to all who have contributed so far)

Silicon Gfx 2 (Demo) by Wfmh -> http://janeway.exotica.org.uk/release.php?id=15639

WinUAE2810, A1200 (basic) -> strange glitches (see on pics)

p.s.
1) Quickstart A1200 basic config.
2) "CD & Hard drives" -> "Select Archive or Plain file" and choose "WFMH-SiliconGfx2.LHA"
3) Start the emu
4) type: SG2 (enter)

This is stupid bug in recent BPL1DAT vs sprite side-effect that forgot to handle AGA sprites in border area feature correctly. Probably breaks some other demos too..

The Rise of Antrax (Trackmo) by Balloons -> http://janeway.exotica.org.uk/release.php?id=71447

WinUAE2810, A1200 (+4Mb) -> some glitches -> see pic.


Picture Book (Trackmo) by Axis -> http://janeway.exotica.org.uk/release.php?id=10883

WinUAE2810, A1200 (basic) -> strange glitches while disk2 change blinks (see on pic)

As I said previously, I don't have plain fast RAM expansions for A1200. Can't test.

A1200 confirmed.

Ok, these are just for info then. (but also there are already plenty those for basic A1200 config. still waiting to be checked/confirmed ... see on 1st page) :)

That kind of right border bug emulation is quite new (few versions ago there was no gap) but unfortunately it is correct.

Ship glitch does not happen, probably the usual cause again.

(and try to list less boring demos..)

Both A1200 confirmed.

Not confirmed but demo also runs slightly slower on real A1200 so the usual CPU timing.

A1200 confirmed. (Those kind of vector object bugs are perfectly normal, limited accuracy when using integers)

Confirmed (both glitches) but glitch pixel pattern isn't 100% identical.

Ship does glitches, just save state before earth part. (yes, it happens really fast)(another example on pic below)

A1200 confirmed.

Bottom screen garbage A1200 confirmed.

Not A1200 confirmed but you know the reason already..

Top screen garbage A1200 confirmed.

I meant it does not glitch on real A1200. (and reason why it does not was included). Minimal answers only!

Grass60 (Intro) by Grasshopper Developments -> http://janeway.exotica.org.uk/release.php?id=16455 (A1200 basic)(pic1)

Jtxrules (Intro) by Illusion (new) -> http://janeway.exotica.org.uk/release.php?id=9859 (A1200 basic)(pic2) ... on link it looks different ?!

Karma Cowboy (Intro) by Passion -> http://janeway.exotica.org.uk/release.php?id=18075 (A1200 basic)(pic3) ... it just stops at pic3 ?!

Nethed (Intro) by Embassy -> http://janeway.exotica.org.uk/release.php?id=10651 (A1200 basic)(pic4) ... HALT1 ?!

The Party 1995 Invitation (Intro) by Polka Brothers -> http://janeway.exotica.org.uk/release.php?id=5202 (A1200 basic)(pic5) ... quick glitches ?!

A1200 confirmed.

Uses some strange programmed display mode that is sort of PAL compatible but also sets BEAMCON0 bits that no one has set previously ("DUAL" bit which apparently does something strange).

It looks even worse in older versions.

A1200 confirmed. (right mouse button exists so it isn't completely hung)

A1200 confirmed. Hangs with "FU" :)

A1200 confirmed. (Finally glitch that looks like CPU problem but is actually correct behavior! Not 100% identical glitch but mostly same and in same positions)

Bonus: White bar in "Shade cluster" part is fixed. (Lots of requirements to trigger it: AGA + at least 1 sprite in horizontal border + bitplane active in same scanline + BPLCON4 XOR bits non-zero)

... and seems "Silicon Gfx 2 (Demo) by Wfmh" problem also !

(and these are just the first results of the hard work that follows) :)
