Title: Palette shifts with DirectDraw
Post by: Buddabing on May 26, 2005, 09:58:38 pm

Hello,

I'm experiencing some weirdness with my cab, which has an ArcadeVGA card installed. When using DirectDraw and MAME, the color palette is wrong. The wings of the green Galaga flagships appear blue, but the white and red look okay. When DirectDraw is turned off with -nodd, the colors appear good but the aspect ratio is all wrong. There's probably a performance hit as well. Colors are fine in front end applications and in the Windows desktop. My DirectX install was the latest (9.0c)

Daphne appears to run okay. Zinc runs okay using the OpenGL renderer, but hangs with the Direct3D renderer.

I just did a soft reinstall of Windows XP Pro and the problem remains the same.

Anyone experienced this? Is there any way to selectively fix just DirectDraw?

Regards,
Buddabing

Do you have the latest ArcadeVGA drivers?

Just the drivers that came with the disk.

I forgot to mention that I have a 7xxx series card.

What version of MAME?  I've got a similar setup and will try to fire it up and check it out.

I tested it, but I want to make sure I'm looking at the same thing.
The flagship is the one who can take your ship, right?

On my regular PC and my cab the wings aren't green, more of a torquoise. I believe this is normal.  -nodd didn't change the color.

My cab has the 7xxx card, WinXP Sp1, and DX 9.0b.   Also from my recollection, the 7xxx series never had a driver update.  Only the 9xxx series, and I want to say they have had or are having a couple updates.

Don't think this really helps.

That's so odd, I wish we know which part did it, XP SP2, directx 9.0c, or whatever else.  I wonder if screenshots would of captured this error.

Just curious, but was my description correct?  (Correct in meaning I was looking at the right thing and I didn't exhibit the problem)
