Some testing
« on: June 09, 2008, 11:12:10 AM »
If anyone has some time I could do with some help in testing something. I've made the following changes to the CPS code;

Quote
- Lagged the sprite palette in all CPS-2 games - fixes issue in ssf2 attract
- Tidied up the CPS-2 split graphics rom loading
- Properly fixed the qadj ninja sprite bug without resorting to hacks

The one I need help testing is the first one - the sprite palette lagging in CPS-2 games. This was previously only enabled in Gigawing but it does resolve the bug posted here. The "zorro mask" is actually drawn by MAME if you enable the debugger and run it slow enough so the issue isn't the fact that it shouldn't be drawn - I believe the issue to be that caused by not lagging the palette with the sprites and this pans out due to the fact that this fixes the issue.

From the little testing I've done it doesn't cause any problems in other CPS-2 games but it would be nice if somebody had the time to compile in the attached changes and do some good testing on all CPS-2 games to look for any problems that weren't there before.

Thanks for anyone that finds the time.

Hmm, I don't repro that bug on my build - and to be honest it wouldn't make sense that lagging the sprite palette would cause that!

Oh, and the driver doesn't need BDF_16BIT_ONLY. It supports all colour depths in it's rendering.

There seems to be a bug in some of the rendering code as I have the same problem on a laptop here. What graphics chipset are you using? I might get chance to take a look this week.

Hmm, I think I'll flag CPS drivers as BDF_16BIT_ONLY then. I wonder how long this has existed? I use 32-bit depth on both my desktop (nVidia 8800) and my laptop (ATI) and none of those problems repro. I wonder if it's a GCC vc VC thing? I'm testing with GCC.

VC builds work fine here (on my desktop) so that's not the issue. :)

Just tested the build Bison posted and the issue does exist when I use that one. Not sure what happened but it's in that build. :)

Scratch all that - it's a blitter issue as previously described. :)

Seems to be worse with the scanlines enabled on my media centre PC. Crashes FBA with a memory leak for some reason. Can't run visual studio on it tho so trying to remember how to use gbd and failing. :)
