Tested in beta 8 QS A500 (most common).

EDIT: But with ECS Agnus seems to run fine. So, forget on this one.

Also, I am not interested anymore to continue with verifying further pages as most of those other demos looks to be boring and not such demanding for an WinUAE emu testing as previous.

Hope that those already verified should cover enough demo coding tricks, if not all possible, so that there is then no need to continue with further testings.
But if there anyone who would want to continue, just go ahead!

p.s. Now only waiting for next official (fixed) version of WinUAE to come out. Hope it will happen before

.

EDIT:
Reminder on comments and current status -> http://eab.abime.net/911206-post57.html

Well, just from curiosity have been continued with pages 17,18,19,20 and now really decided to stop with further testing ... see no point as those demos are really look to be very simple in comparison to all others already tested before.

So, that would be now 20 pages x 25 demos/page = 500 demos already tested.

Current list of demos waiting to be fixed (acc. to http://eab.abime.net/911206-post57.html):

The end by trilobit
Hotbleeps by Loonies
Antediluvian Sloppy Spectacle by essence
COOL FRIDGE by UPFRONT
Megademo by Royal Amiga Force
Pax Americana by Complex

Some of above will maybe be difficult or impossible to fix without some more docs/schematics/diagrams that is required.

Others has already been fixed in newest WinUAE 2.7.0 Beta 8 version.

QS A500 need only 512kb ... scrolling text is blinking from pic.1 to pic.2 ...!

Another writing to blitter registers while blitter is already doing stuff. (Just check the log, these conditions are logged)

As I said, it allows emulation of async turbo boards. Also it allows custom values, for example if someone wants to adjust game speed very carefully.

Quote:

Does 3.549865 freq. meaning something important?

It is chipset "color" clock (dma clock) = 1:1 CPU/chipset ratio. It is listed because it is smallest ratio that UAE can support. (Agnus DMA clock is the base timing unit)

Uses unemulated OCS feature (another: "keep hacking until it works instead of simply fixing the tiny bug in copper list", this is quite common in old, like 1988/87 or so demos), fixed. On ECS scroller does jump around but it does not get as corrupted as in emulation. (Not sure whats the cause)

A500 confirmed. No idea why sprite DMA is enabled or pointers point to garbage, probably usual "works accidentally using some specific configuration"..

Thanks again for very detail explanation as usual.

Yes, indeed: "BLITTER: channel mode changed while active (09->01) PC=00013d7c"

Critical Mass by Parallax (DMS) OR Critical Mass by Parallax (ADF)

Using QS A500+ ... it runs till pic.3 and then just stops?!

Have tried running the demo using both DMS or ADF versions, and got same behaving!

Maybe it needs some special configuration ... does anybody ever manage to run any of this demo files?

amilo3438 · 23 September 2013, 23:50

Application-Trackmo

QS A500 OCS/ECS ... "BLITTER: register modification during linedraw!"

EDIT: New dms file found that hasnt such problem (pic.2): Trackmo (Trackmo) by Application

This one has troubles running on a real A500 too, I think the main reason was a really buggy loader.

Toni Wilen · 24 September 2013, 08:45

All known images of Critical Mass have broken landscape part at the beginning. 1M chip ram config usually prevents the crash.

Later it usually hangs (can happen on real hardware too but appears to be more rare, probably some internal CIA timing not yet fully emulated), reason is simple: music player (which uses CIA) can clear CIA interrupt register when trackloader is using CIA for delays, unfortunately trackloader CIA delay uses same CIA chip (but different timer) and it also polls interrupt register. It should have polled CIA timer on/off bit.

Now fully emulated, scroller will jump correctly in ECS mode

Fixed. (Modifying bitplane modulo one cycle before modulo is added will use old value)

Same corruption seen on my real A500.

This was really boring to watch on real hardware. No warp mode..

But yes, exact same fill leak happens on my real A500, including quite jittery speed.

EDIT: It even crashes identically when it says "What about some nice overscan 32 colors inconvex shaded filled vectors in one frame" (Borken executable?)

So, that would be now 20 pages x 25 demos/page = 500 demos already tested.

Again, just from curiosity finished with testing next 8 pages, thus it would be now 28 x 25 = 700 demos already tested from pouet link ...
and that present almost 30% of all Amiga OCS/ECS demos currently existing there.

Well, I have also reached the point where continuing with further demo testing make no more fun anymore, so that would be all for now ... and this time mean ... real.

I have already added those new findings in the demo status list http://eab.abime.net/911206-post57.html so everything now can be found on one place.

A little statistics:
----------------
700 demos tested
27 problems found
12 found not to be an emu problem
6 demos already fixed now
9 demos remain to verify and/or fix .... and that present 1.29% of all already tested demos!

Toni Wilen · 25 September 2013, 08:34

Could you put demos that have "blitter active" issues in separate list? (In first post for example) I am planning to examine them more carefully later.

Just for info...
Well, the above does not mean completely giving up...
I will certainly continue, but much slower pace, very slowly, very...
