NAMCO MUSEUM BATTLE COLLECTION (ULUS100035) Pac-Man Arrangement lighting/color issue

[Peduls]

What happens?

When playing the Pac-Man Arrangement game the ghosts and pac-man appear darkened and off color.

What should happen?

When playing the game on actual hardware the ghosts and pac-man appear much brighter in color.

What hardware, operating system, and PPSSPP version? On desktop, GPU matters for graphical issues.

Hm, pretty sure this used to work, must have been one of the spline tessellation rewrites...

Could you try exporting a GE frame dump? These help a lot.

See here for instructions - it's not hard and works on Android too:

You can zip that and then drag and drop it into a reply here.

They are drawn using splines, early (24/247):

• Lighting with one light, separate specular + diffuse
• Fog: at 100, slope=2, color=white
• Alpha blend (simple src.a / 1.0 - src.a)
• Solid color, no texture or vertex color

Software is also wrong. The dump shows correct on a real PSP. It seems pretty clear that light 0 is not applying correctly.

#12372 improves this, at least back to how it was. But the tessellation is still wrong, because the ghosts have dark spots at the tops of their heads...
