I thought you already had these problematic demos somewhere on your hard drive so I gave the file names instead of the full name. (to make it easier)

Ps. On second thought, I may have been a little lazy to find the full names.

Slam Tilt (1996)(21st Century)(AGA)[cr DLM](Disk 1 of 5).adf - intro has problem only when Cycle-exact (DMA/Memory accesses) mode is set!
Fine with Cycle-exact (Full) or when both is off.
Tested in QS A1200 basic configuration.

Small status report: blitter vs CPU timing has something weird going which partially explains TOMMY-Bobs and MAYHEM-Expiration. I'll probably add missing blitter pipeline emulation first because it is also needed for accurate emulation.

I am still not exactly sure how CPU/blitter priorities really are supposed to work because according to schematics blitter also uses same RGA pipeline which means blitter DMA request is done 2 cycles before it appears in external RGA bus.

Do you need new tests (OCS / ECS Demos) before the next betas ?

[White]

Toni,
yesterday i downloaded the version in the first post of this thread
is dated:
26-09-2020
version 4.5.0 public beta1

is this the one to use with uaegfx for testing?
thank you

[White]

with beta version 4.5.0 beta1 using uaegfx
with the same configuration and same system
with directx 9 and directx11
if I promote a "MUI" screen
the graphics are completely distorted

while with the final version 4.4.0 this problem does not occur.

when I get it working the beta 4.9.0 beta 19 (28-04-2021) is not affected by this problem

the version 4.5.1 beta 1 is stable unlike the beta 4.9.0 beta 19 (28-04-2021)

@White

I don't understand the problem.
Beta 1 was first beta and probably had more issues than the last b19.

[White]

@Zarnal
currently what is the latest version to try ?
I can't understand it :-)
thank you

Beta 19.

[Toni Wilen]

Always use latest beta. Unless specifically beta is not good for "generic" use. B19 should be fine. (Except FSINCOS crash but normally it isn't used)

The Sunrise (Demo) by Anadune --> https://www.pouet.net/prod.php?which=17868

Is glitching on the bottom on part with "Mr. Light" text and after:
i.e. part of "Mr. Light" text on this pic.: http://kestra.exotica.org.uk/files/s...000/11253e.png

Seems like some new AGA bitplane scandoubling problem!

PS. Latest WinUAE Beta19 QS A4000 040 config!

Urea by Rave Network Overscan -> https://www.pouet.net/prod.php?which=2320

When press LMB mouse on the last screen with scrolling text it open the debugger window! (in 4.4.0 it not)

PS. Latest WinUAE Beta19 QS A4000 030 config!

Confirmed in two scenes ( see pic 1 ). Also in Quickstart A1200.

Edit : since b18.

Hi Toni,

Please see this thread in relation to "Formula 1 Grand Prix".

Most b18 glitches fixed.

Beta 19:

- Bitplane max plane limit was calculated before internal aga=true variable was set. Loading AGA statefile forced OCS/ECS limits if FMODE was not updated in copper list.
- Fixed sprite glitches in some situations.
- Fixed graphics glitches if resolution was changed in horizontal blanking region.
- Different bitplane delay for odd and even planes didn't work correctly in some situations.
- Fixed memory buffer overflow when some types of file dialog was opened. (old bug)

Note: "Remove interlace artifacts" Display panel option is currently not supported. It must be disabled.
Note: Blitter cycle allocation is not yet pipelined. (Which is the real cause for 2 idle cycles after writing to BLTSIZE.) This will most likely affect copper blitter wait timing.

No 64-bit version?

[Toni Wilen]

Check post #559.

Status: blitter internal RGA pipelining update is almost done. Last piece of new chipset emulation update.

I had initially reported my issue with screen dragging on the P96 thread but would like to post it here as well for better visibility.
http://eab.abime.net/showpost.php?p=...&postcount=126

I tried the same on a more default WB as instructed; however, I still could not get screen dragging to work properly.

Custom chipset emulation rewrite is almost complete. Non-chipset emulation related bugs can be reported and they aren't ignored anymore

Beta 20:

- Blitter internal RGA bus pipeline emulation implemented.
- When blitter was started for the first time and cycle-exact mode: blitter idle time from start of scanline to BLTSIZE write position was not emulated cycle-exactly. Almost harmless previously, now it caused visible problems with statefiles that expected blitter to steal all cycles. Very old bug.
- Copper didn't stop when both COPJMP1 and COPJMP2 was strobed without active copper DMA. (b18)
- Copper WAIT wrong special case fixed. (Hotbleeps and EyeQlazer)
- Blitter register modification while active update. (For example fixes Demo Mix 5 intro / Tommyknockers). Not 100% yet.
- AGA FMODE bit 14 bitplane scandoubling odd/even scanlines were swapped. (b18)
- Optimized mode bitplane emulation didn't do anything if scanline's bitplane pointers crossed end of chip ram. Normally never happens but really weird programs or free running bitplane pointers might not have been 100% accurately emulated ("Warning: Bad playfield pointer" message). Ancient bug with ancient comment (probably from pre-0.8 UAE) that this should be fixed someday..
- Some more UHRES parts implemented. (Yes, this is useless but cycle usage still should match real hardware if UHRES is enabled for some weird reason!)
- b18 FSINCOS update broke non-softfloat FSINCOS.

[Zarnal]

These demos still have a problem with b20 :

UpToFront- CoolFridge :

" Smooth-Copper " : The second logo (with copper effect) is corrupted and the scrolltext has a problem at the same time (pic 1). Since b12

Note : http://eab.abime.net/showpost.php?p=910834&postcount=50


" Flexible-Zoom " : The effect is not correct (pic 2). Pic 3 shows how this effect should display normally.

Thanks.

Edit : pic 2 is also no correct ( thank Amilo3438 )
