Jointro (Intro) by Analog

A500 OCS/ECS ... Some glitches after pic.1 is shown? ... depends of mem. config. (see on pic.2 & pic.3)

EDIT:
Short and Fast Production (Intro) by Analog

After the weird wired cube rotation part finished, on top line appears small gap that last aprox. 1sec (pic.4)?!

EDIT2:
Meeting Demo (Demo) by Celtic

The logo and text scroller seems to have some "slowing down" problem (pic.5)?! (p.s. Also it seems to work fine if Cycle-exact box unchecked!)

Megademo by Cult

A500 OCS ... The 1st loading screen looks fine (pic.1), but the following 3 loading screens has some glitches (pic.2,3,4)?! ... and after is again fine.
(ps. It doesnt happens on ECS Agnus.)

EDIT: It seems on OCS works fine only on 0,5mb chip memory!

A500 confirmed.

Same. (Probably some sprite pointer being corrupted for few moments)

And A500 confirmed too. It seems it requires KS 1.2 or older. (Demos that keep ROM vblank interrupt handler active can work strangely, something changed between KS 1.2 and 1.3)

This is weird one. Background is black with KS 1.1, 1.2+ and top 3/4 is blue, bottom part is black..

Tested on A1000 using 1.1, 1.2 and 1.3.

Confirmed. Another demo with sprite pointers pointing to garbage and garbage is different with different memory configs.

Meeting Demo (Demo) by Celtic ... confirmed to work fine in latest test WinUAE (1.2 KS, OCS , 512KB Chip RAM)! (How strange, I thought I had already checked.)

Seems to be yet another KS 1.2 demo. Possibly uses ROM contents as random numbers to position green sprite objects. If sprite 7 is drawn down enough, it will start duplicating same graphics forever because DDFSTRT changes from $38 to $30 which steals sprite 7 DMA cycles..

And this is yet another "MoreNewStuffy" (and Alpha and Omega) update problem, adjusted but it probably still isn't exactly right, needs more testing, someday..

(btw, Alpha and Omega / PMC didn't actually work in older versions, scroller had other kinds of issues..)

$dff180 is never set in the main copperlist except for the last part ($f001fffe) where it's set to black. So it most probably uses the system-colors. Strange that it's black with 1.1 though, different system copperlist?

KS 1.1 copper list 1 does not modify COLOR0. I think this is simply bad "rip" and originally it came with different loader or menu or whatever..

Bootblock is run with sprite DMA off. This is probably bad bootblock rip that does not "emulate" bootblock environment fully.

The McDisk2 disk uses a system-configuration with color0 = black. Either this was made on purpose because of the bug in the intro or it's just a coincidence and the coder didn't even know about the color0 problem.

Neon Skates Demo by End Of Century 1999

It crashes after some loading time (pic.1)! ... Weird, as there is a picture on link above (pic.2)!

(p.s. Also have checked other CPUs and got almost same behaving.)

EDIT: It seems to be a false alarm ... it works fine from WB. (Wow, that was fast ... thanks Toni)

Yes, it does.

More interestingly only background colors are visible when running on A1000. More testing to do..

EDIT: Yes, A1000 Agnus does not enable bitplanes if vertical DIW is zero. Only 1 and larger works. (Probably related to another A1000 Agnus bug, vsync strobe line is line 1, not line 0)
