Megademo 1 by Perfect Cracking Team

A500 OCS/ECS (most common) ... text glitches on last part ... pic.1 !!!

First Demo (Demo) by Perfect Illusion

JFI ... Another demo with high CPU usage on simple scrolling text screen !!!
I have made test with CE=ON and CE=OFF (see pic.2) and it starts to drop down on flag screen (same pic as shown on link above)!

A500 confirmed. (and scroller that appears with right mouse button is corrupted too)

Still don't really care but perhaps "wait for vertical line x" cpu polling loop is relatively slow to emulate (extra vpos/hpos count calculations needed) and because there is nothing else happening, cpu has lots more time than normally = it executes lots more instructions per frame.

The Ringard Production Megademo most certainly works as expected.

Those screens mimic a french pay TV channel (Canal+) as it can be viewed when you don't own the decoder box (both image and sound are scrambled)

Fixed. (Accidentally abuses copper getting stopped when both strobe registers are accessed while DMA is stopped, worked incorrectly if yet another strobe was done)

A500 confirmed! (EDIT: It "works correctly" when using 2.7.0 or older: this was made using emulation which wasn't working correctly until few days ago..)

Toni Wilen · 15 December 2013, 13:36

Remaining vertical "copper" bar demos fixed. (Profecy-LetsRave has some flickering pixels where bars join but it happens on real A500 too, quite difficult to see on normal display)

Fix was quite boring: blitter's last idle cycle (just before final D write) does not need to be free cycle, only "normal" idle cycles need free bus.

Yeah, more or less. It's one of the many "anti-demos" that were released quite often back in the day. And most of them were real crap.

Seems to be same on real A500. I think my previous test was too quick, glitches aren't that easy to see when pixels are blurry. (Going to test with Indivision ECS connected later, should be more clear)

EDIT: Indivision ECS tested: exactly same glitches as in emulation. They were clear as day with Indivision connected

Does not happen on real A500 but there is something strange going on because exactly identical glitch appears if I enter Action Replay 3 and then exit it..

EDIT: AR3 is just a side-effect, nothing to do with real problem, it is emulation missing feature that hasn't been triggered until now. Demo has really funny accidental bug.

Copperlist sets 3 plane lores mode, then after 3 full bitplane fetches it writes zero to BPLCON0, immediately after last "fetch block's" BPL1DAT write. This last write has some zeros in upper bits (something like $0xxx), Denise is quick enough to switch of bitplane output just before non-zero data gets shifted out.. This "Agnus fetched it all but Denise didn't output it all" condition isn't emulated.

100% accidental, there is no way coder did this on purpose

EDIT2: Above is slightly wrong, writing to BPLCON0 after Denise starts shifting won't do anything but if BPLCON0 is written immediately after BPL1DAT write, it will prevent Denise from starting to output new 16 bits of data.

Corrupted logo is confirmed, depends on memory configuration.

Same problem on real A500 or A1200. It has AGA-only registers in copper list.

Probably usual "lets disable sprite dma while it is active" bug. (I couldn't duplicate it by just starting emulation with disk in drive)

Quote:

Second Attempt (Demo) by Shade

A500 OCS/ECS (most common) ... pic.2 ?!

Fixed. move.w #xxx,$dff058 had prefetch after write, it should be before write. 4 CPU cycle difference only.. (MOVEs use special microcode in real 68000 and many of them work differently than "normal" instructions, others may still be wrong)

Face It (Trackmo) by Strangers

A500 ECS 0.5+0.5 or 1mb chip ... strange behaving -> B-Trap or Exception 3 !!!

(p.s. Has been verified on the latest test winuae.zip 2013-12-16 19:41)

EDIT: Weird, now managed to finish the demo with ECS 0.5+0.5 and disk already inserted !

EDIT2: And also works fine if disk inserted after WB hand ! (not "WARP mode" has been used in any of these 2 cases)

Possible reason: It seems the demo is somehow sensitive if "WARP mode" is used ... also confirmed !

p.s. If there is someone still not sure how to enable/disable "WARP mode" = "END key" + "Pause-Break key" !!!
