Picasso IV Chip Upgrades
« on: November 30, 2007, 03:45:02 AM »
Hello everyone,

I'm having some issues with my Picasso IV in my A4000D, namely:
- 50Hz interlaced screens flicker like crazy (they look nothing like output from my 3000 on the same monitor)
- I get some reddish speckling in white areas of some games
- Scrolling in some games (e.g. Deluxe Galaga) is not perfectly smooth - it seems to "jump" a little bit here and there in the Meteor Storm

I've already adjusted the flicker-fixer to promote PAL screens to 100Hz, but it hasn't helped.  Based on what I've read in other threads, I ran P4Info and found that some of my chips are not the newest versions.  The pertinent output for my card is:

Opened PicassoIV.resource 7.1 at $7003434
p4bi_BridgeRevision $1
p4bi_FlickerFixerRevision $7

Is there anything that can be done about this?  Anyone know if Tobias Seiler or anyone else has replacement chips?  Thanks in advance!
