Problematic Demos.

Plasma Explosion (Demo) by Timex

A500 OCS/ECS (most common) ... pic.1 !!!

Fixed. Similar problem to another demo that had 16 pixels of garbage flickering mid screen. (buffer not erased properly)

This change affects many many demos. Hopefully it does not break anything (and if it does, it means something else is still broken)

EDIT:
Crazy World (Demo) by Dioxide ... it looks much better, so ... maybe it should be tested on a real Amiga with Indivision ECS to confirm is it the same now !!!

I already did and it did looked exact same, different colored pixels on top of each "step" is correct. (Today's update had no effect).

Ok, so it was never a problem there ... probably I had misunderstand something there -> http://eab.abime.net/showpost.php?p=...&postcount=422

It was broken in 2.7.0 and older. Difference is obvious if you save statefile and load it to 2.7.0 (or older) and current development version and compare it.

A500/A1000 confirmed. (Broken image? Reset after this part can't be right)

Remarkable Intro (Demo) by The Outrunners

A500 OCS/ECS (most common) ... HALT1 !!! (Also on KS1.2 it resets !!!)

Coder decided that you can "open" dos.library with "lea $5c68,a6". Looks like KS 1.2 (33.180) is the only one that matches this address if config is chip ram only.

I didn't manage to run it on A1000 either with same KS version.

Golden Oracle (Demo) by The Purple Vortex Cooperation

A500 OCS/ECS (most common) ... pic.1 !!!

Confirmed. Any kind of gaps or glitches on filled vector objects that don't cause fill "leak" (horizontal lines leaking to left or right side of object) are generally normal.

Starbugs New A500 Demo (Demo) by Titanics

A500 OCS KS1.2/1.3 ... it seems one pixel doesnt move there -> pic.1 !!!

p.s. Also seams it doesnt works on ECS ... the stars doesnt appear on 1st screen and LMB doesnt work ?!
(Probably similar/same problem as Equipose by Complex -> http://eab.abime.net/showpost.php?p=...&postcount=170)


Demo Mix 5 intro (Intro) by Tommyknockers

A500 OCS/ECS KS1.2/1.3 ... some line appears ... pic.2 !!!


Amiga BTX - Final (Import Intro) by Cascade 1733

Something strange happened here - pic.3 !!! (As it works fine in latest official 2.7.0.)


Vectris (Demo) by Toxic Trooper

A500 OCS/ECS (most common) ... when the demo comes on the greetings part (last part) and after LMB got this message -> pic.4 !!! (winuae.zip 2013-12-21 15:12)


Sony VX-90 (Demo) by Royal Amiga Force

A500 OCS/ECS (most common) ... some line appears -> pic.5 !!! (Note: It didnt appear in 2.7.0 beta16 !!!)

It is OCS only, A1000 confirmed, stuck pixel also confirmed.

Blitter modifications while active, always check the log.

Amiga BTX - Final (Import Intro) by Cascade 1733

I can't duplicate. OCS only.

Vectris (Demo) by Toxic Trooper

A500 OCS/ECS (most common) ... when the demo comes on the greetings part (last part) and after LMB got this message -> pic.4 !!! (winuae.zip 2013-12-21 15:12)

It does stupid "reset" at the end (EDIT: Jumps to ROM entry point in user mode!) It hangs on real hardware. (Not going to be changed, not worth the trouble)

A500 OCS/ECS (most common) ... some line appears -> pic.5 !!! (Note: It didnt appear in 2.7.0 beta16 !!!)

It is very visible on real hardware. Sorry but it is bug in copper list, setting color0 too late (in visible part of screen).

[Toni Wilen]

"Last A500 (Demo) by Oblivion" should work now. (This change can also make a difference in other demos that use blitter linedraw)

[Schlachtwerk]

Ok Thx my Fault, sorry for waste your Time.

Those latest changes also influence on:

I finally found the real reason, very early part (landscape that has the blitter bug that prevented it from working for years..) corrupts one word in music pattern data. I know how to fix it but it isn't simple fix.

Still works fine here, even with your config. (DD vs D3D can't cause this kind of problem, it is something else)

So one day might be also fixed !!!

Its a little strange, but official is compiled with VC10 and test version VC 13, right ?! ... maybe something there causing the problem !!!

ps. Just remember I still running WinUAE on WinXP SP3 !!!

EDIT: Also, just tested, on 2.7.0.beta16 it is OK but on test versions before official 2.7.0 is still bad !!! Betas was also compiled on VC10, right ?!

EDIT2: Strange, it runs fine on "MSVC 2013 (same optimizations as in OP) + SSE2 + __fastcall compiled" version from here:
