Picasso IV..defect

[Amigaz]

ahh..it's that disk...I have it..now I remember
I'll give it a go and use my external SD/FF to get some output before I start messing with the socketed chips  :-)

[Amigaz]

Partial success!!

I hooked up my external DCE SD/FF so I could install Picasso96 from scratch
Transfered PiccassoModeTNG over to the A4000 and ran it and made a new config suited for my monitor and saved into into ROM of the PIV
The prevois config must have been totally retarded

My problem now is that games tend to lag...it's especially apparent in the Pinball series by Digital Illusions

Is there some setting on the PIV I haven't tweaked correctly?

Can you run P4info and post the results?

You probably need to change the default scan rate conversion?

i.e. Set the scandoubler output frequency rate to 50Hz if your monitor supports it.

I'll post those result tomorrow, thanks
Now it's almost ZZzzz time over here

Glad to hear you got it going! :pint:

This seems to be a problem with the PIV, at least my revision of the card (1.2N) with all the "latest" chips is also affected.

All you can do is tweak the frequencies to get it close as possible. If you get it looking good with a pinball game, most other things will look perfect.

Some info I posted in an earlier thread about this:

PAL line frequency (in the TNG tool) needs to be as close to 31.5552 as possible.

NTSC hsync needs to be at or slightly above 31.4857.

If someone here has an earlier revision PIV which does scroll perfectly, I would be interested in seeing a screenshot from the TNG tool, showing the PAL/NTSC settings.

I get the "comb" artiffacts on Pimball Illusions, don't remember getting any lag. To eliminate the comb effect you must turn off "Interlace capture" on the flicker fixer options of the picasso start up screen.

Have no clue what revision my card is...
I hope my tweaking of the settings with the TNG util will help  :-)

Maybe you can call it "comb effect" I think it's the correct word for what I'm having here

How do I access the Picasso startup secreen?

I noticed I also have a bit of flickering in Pinball Illusions in the high res. laced modes

The version of your PCB is written on the card in Silk Screen.

If you post the results of P4INFO then we will know what revisions of PIV chips and firmware you have.

The boot menu is activated by holding down either [Shift] key when resetting the machine. (Only available on later firmware)

See Chapter 6

T tried this but am still getting the comb effect...

I set the line frequency to the above value and the combv effect vanished but now I'm looking at a screen with 50hz refresh *my eyes!!*  :-o

Hey AMIGAZ,

My suggestion - jot down the frequencies when the scrolling is smooth. Go into the PIV boot menu and set the scanrate to double (100/120Hz). Then try to fine tune the line frequency until it's double where it's at now at the working 50/60Hz settings, and you should be OK. (So, if PAL vfreq is around 50.4Hz now, it needs to be at 100.8Hz for a flicker-less picture on your CRT.)

Basically, the default PIV settings are close, but not an exact double/multiple of what the Amiga outputs - so the Amiga and PIV are not synchronized, hence the annoying screen jerking (and artifacts on static screens).
