While checking some already fixed demos in new Beta12 found this:

Feel Blue (Intro) by Oblivion aka First

winuealog -> "Illegal instruction: 4afc at 00C077F6 -> 00C077F8" ... it happens on the decompression screen!

Perfectly normal, most likely demo has CPU type detection. (Tries to execute 68010+ instruction, if exception -> it is 68000. Same as KS CPU detection.)

Pizza & Coke - menu (Intro) by Arise

A500+ (Basic) ... with 68000 or 68010 got Exception 3, but with 68020 works fine.
So its probably then for 68020 or somethings is wrong?

Coop Demo (Intro) by Arise & Awake

A500+ (Basic) ... Exception 3 ?!

Xmas Demo by Beyond 2000

A500, KS1.3, OCS, 0.5mb+0.5mb ... Some blue line as shown on pic.1 ?! ... Does it happens on a real A500?

(Btw. On ECS it just stops ... on OCS (1.3, 0.5mb only) it has scrolling text garbage -> pic.2.)

Why A500+? No demo is made for A500+

Yes and yes. (It does not work with 0.5M, it unpacks over CLI screen which corrupts data)

Not working on ECS: demo has a bug in code that copies color values to color registers, it writes past color registers, including writing zero to BEAMCON0 (ECS register) which changes screen mode to NTSC and demo hangs because it waits for vertical line number that is PAL only..

Yeah, probably right, but on A500 OCS/ECS got pic. below?!

Also, it works fine only on A1200 AGA and ECS Full config. with 68020 CPU!

p.s. Above mentioned apply for "Pizza & Coke - menu (Intro) by Arise" ... as the "Coop Demo (Intro) by Arise & Awakeother" doesnt work even with 68020?!

"Coop Demo (Intro) by Arise & Awake" works fine here using normal A500 config.

"Pizza & Coke - menu (Intro) by Arise" requires 68020+. (or someone repacked it using some 68020+ only code?)

Yes. Again uses ECS/AGA only display position bits. (This time not accidentally because it only works with ECS!)

The Spacecrafts (Demo) by Clones

The glitches on lower left corner (pic.1) happens only on OCS?! (on ECS looks fine)

Yes, confirmed (A500 ECS vs A1000)

Can I Play With Madness ? (Demo) by Defcon One

A500 OCS ... glitches (pic.1) caused by blitter issue (pic.2)! (Note: It doesnt happens on ECS!)

EDIT: Well, it happens also on ECS ... (tested in Beta12)

EDIT1: Also, in latest winuae.zip on A500 ECS scanlines3 seems it doesnt happens (pic.4)!

EDIT2: Maybe to early conclusion with EDIT1! Tested again on latest winuae.zip and got pic.4 and then pic.1, so its random!

New Demo -2nd Demo- (Demo) by Defcon One

A500 OCS 512mb ... pic.3 ?!

p.s. It looks this one doesnt have such problem! -> Official (Demo) by Defcon One

Party Time (Demo) by Defcon One

winuaelog -> "BLITTER: register modification during linedraw! 000450e6"

amilo3438 · 14 November 2013, 17:10

Orchasm (Intro) by Diffusion

winuaelog -> "BLITTER: register modification during linedraw! 00011bc6" ... (pic.1)

EDIT: Its 1st case where BLITTER issue stops executing demo!

EDIT1: On A500 ECS 1mb chip there is no any BLITTER issues ... its running fine?!

This could be a simple demo bug, I think it is possible to exit vector part while blitter line draw is active and demo fails to wait for blitter before it starts screen clear blit. (I am not going to test this on real hardware, too boring)

Quote:

New Demo -2nd Demo- (Demo) by Defcon One

Yes, it does happen.

amilo3438 · 14 November 2013, 18:55

Meeting Intro (Intro) by Disknet

A500 OCS/ECS ... if inserted after WB hand -> pic.1, otherwise it runs better but not without small issues -> pic.2 !!!

p.s. Glitches on pic.2 reminds on CPU speed issue, but its different as disabling cycle-exact nothing changed, so un-checking CE didnt help?!

EDIT: Does it behave same on a real A500?! (hope this one doesnt look boring)

p.s. It behaves same but it doesnt look such bad in WinUAE 2.0.1!

amilo3438 · 15 November 2013, 18:46

27-328 [1162 076-151]: BLITTER: D-channel without nothing to do?

amilo3438 · 15 November 2013, 22:32

TV Demo (Demo) by Energy

When demo starts there is some glitches on rotating balls logo (pic.1,2) for a few seconds ?!

EDIT: Note: It doesnt happens on WinUAE 2.0.1 ... at least it doesnt look such bad.

The Energy Copydisk Intro (Intro) by Energy

Some glitches on pic.3 and pic.4 ?! ... Does it happens also on a real Amiga ?!

Transfusion (Demo) by Extacy

amilo3438 · 16 November 2013, 17:37

No glitches on A500. Code is horribly unoptimized, there is no need to save and load all values to/from memory, 68000 has lots of registers..

And yes. It is practically invisible on any normal TV.

Well, in my opinion, code is optimized or not = who cares.

Only what is important should be = "Does it happens on a real A500." ... right ?!

p.s. There is no excuse for "bad emulation"!

EDIT: Regarding the "bad emulation" ... it was a joke.
The current emulation is indeed not bad at all ...
Then its quite opposite, every day it becomes better and better = it becomes now very hard to find any new problem ...
So that each new problem has no need to be considered irrelevant = it could be of use to improve/optimize the emulation even a bit more if possible.

Party Demo by Ghostriders

Broken in 2.5.1 or previous (pic.1)!!! ... confirmed to work fine on 2.4.1.

EDIT: JFI - And this one, as it looks, doesnt work in OCS/ECS but also stop to work in AGA after 2.7.0 Beta8 version:
