Toni, the bitplane vertical stripe seems really a bug.

EDIT: I didn't see the bug at first because I usually associate Subpixel emulation with Resolution=SuperHires (to see all the 35ns pixels).
But if you select Subpixel and Resolution=Hires(normal), the vertical stripe appears.

It looks like upper right "hole" was also on the A1200 floppy version? It may be not a WHDLoad bug... (At 9:00 a hi-res section)

Fixed but not yet sure if it is complete fix without any side-effects.

hexaae · 21 November 2019, 01:18

Will test many games with the last build and report if I see something strange.

Hi Toni, just noticed this glitch on WB with winuae.7z 20/11.

Max usable overscan system settings: DDFSTRT=$18, DDFSTOP=$d8, FMODE=3 and Subpixel emulation active.

No problem on official PB5 or with no Subpixels display.

Thanks, it works properly now

Hello folks, i have contacted CFOU, because both fixes from Toni & him do not work on my 1200 for Shadow of the Beast. The Beast logo and the trees are disabled by default, and instead i have some corruption on screen.

i will test soon on two real amiga

escom 1200 +68060
commodore 1200 +68030

Toni Wilen · 15 December 2019, 13:48

I tested it with real A4000 + 68040 or 68060 (don't remember which one was installed when I tested it).

Photo would be much more useful than text that basically says "it does not work"

teste on real escom a1200+blizzard 1260 +SCsCI board +32MO
=> both supported version works perfectly

can you give us more precisions?
configuration?
photo?

dlfrsilver · 16 December 2019, 08:42

First my configuration : A1200 + Blizzard 030 @ 50mhz + 32mb of fast.

the beast logo and the trees are replaced by a whitish band of corruption in the middle of the screen.

I will post a screen once back from work.

hexaae · 16 December 2019, 14:47

Aladdin: vertical line on the left border when "Subpixel display emulation = ON"
WinUAE 4.3.0b9

Toni Wilen · 16 December 2019, 17:00

Happens in real world too (A4000 + 68060). Oddly enough whdload version without preload does not have it but with preload it appears. Exact same behavior in emulation too.

A bug somewhere (WHDLoad? slave?).

When you use PRELOAD there is no more the usual 'black screen' to do a scatter loading.
During this flashes the COP2LC is (re)set to $1000 that contain a CEND and is no more set to a valid ptr for the COLOR00 synced gradient that on AGA do the half pixel bug.

ok here it is :

have you test with NoCache tooltype (not needed on 060)

Can you sen to me your installed to verify disk image? =>perhaps corrupted

indeed this type of GFX corruption can not be caused by both sub-pixel fixes

it's data corruption

yes i will send you my images. But if there are was corruption, rawdic would have failed loading the MFM images, don't you think ?

Too many unknown variables. IMHO it is much better for someone to upload confirmed working archive.

Something to correct in WHDLoad itself?
