Ugh! WHDload version hangs with WinUAE 4.9.1

Asman · 19 April 2022, 14:06

Hi Toni,

When I run the game I realized that after title there is just black screen. First I thought that there is some kind delay and I need to wait. But after a few minutes nothing happen. So I grab problematic routine and check in Asm-One and also wait forever.

Code:

start
;	dc.w	$4a39,$00df,$f006
;	dc.w	$66f8
;	dc.w	$0839,$0000,$00df,$f005
;	dc.w	$66ee
;	dc.w	$4e75
end

Wait	TST.B	$00DFF006
	BNE.B	Wait
	BTST	#$00,$00DFF005
	BNE.B	Wait
	RTS

It is happen in 4.9.1 version.
In version 4.4.0 works like a charm.

Is it bug or I'm missing something ?

@Zarnal, @dlfrsilver
Thanks for checking. I figured out that for 68030 and MMU it hangs. When I just set 68030 (without MMU) it works nice.

Did you uncomment the MMU from the whdload.prefs? I tried it with both jit and with an MMU and the game ran just fine.

this code waits using VPOS and VHPOS. I suspect that depending on the speed the loop never ends.

I had to recently disable such vpos wait in a flashtro when running from whdload.

It is bad code if vblank interrupt is active at the same time (or blitter stealing all cycles)

Normally interrupt starts few cycles after start of frame (first refresh slot position) but this is only emulated in accurate modes. It can still miss frames, even on real hardware.

should be fixed from whdload, or played from floppy with "more compatible" mode... not a winuae issue, more a "expanded amiga" issue.
