picasso IV again

orange · 11 March 2011, 21:56

well it seems I finally solved almost all of the problems with that card, after re-seating all the chips.
but I tried Earth2140 game, and there are some short black lines showing up randomly here and there. could it be hardware?

what other rtg game could be used as a definite test?

Hey,

Sorry to hear your problems could be back.

Here are the RTG games:

All the best.

I doubt the hardware is faulty. Are you using P96? I remember some random flickering black lines in 8-bit screens with the CGX emulation. I had the same issue on both the CV3D and PIV.

I'm using Picasso96 with my PicassoIV and all the games I've played have been fine

Random black lines talks to me about graphics corruption on modern laptops, the last one I fixed was a Qosmio G30.

Technology may change, but the principle remains the same, be thankful you can resolder the ram pins without having to rely on reheating / reflowing and praying.

Wish I had the game to try, but I've never played it. The similar problem I experienced was definitely software related, all my PIV's do it and my CV3D did it. In my case it popped up while running CGX demos under P96.

yes, I'm using P96. workbench looks fine.
I've tried FoundationRTG and it also works good.

there are some CPU slot problems with this a4000, not sure if they are related.

I had problems on my Amiga 4000, and when I switched the crystal on the motherboard from 25 Mhz to 20 Mhz it all worked fine... not sure why.

just tried Napalm, same problem with short black lines. perhaps I damaged RAM chips when cleaning dust with brush :/
is there a way to test RAM on rtg card?

fitzsteve · 13 March 2011, 13:23

There is a Graphics test in SYSSpeed - not sure it down what you need though.

FWIW, I just tried Napalm on 2 PIV's, and get the same flickering lines I experienced when running certain CGX demos. (Some demos the lines are absent or barely noticeable, other times it's more pronounced, but it's 100% repeatable/predictable behavior.) IIRC, the problem went away when I tested the same demos using CGX.

Might be worth resetting all the settings stored in the NVRAM on the card?

I think you can do this with PicassoTNG

ok, thanks.
Simon 2 and Nightlong seem to work great. I'm beginning to see a pattern here. Adventure games don't have problems.
I will install CGX one day.
