Me and My Katamari, PPSSPP Android Graphical Bug

[Gabi1117]

Me and My Katamari. In the turtle level, glass appears black. You can see the bug in this video:

I've seen actual psp playthroughs of the game, and it's not supposed to be that way. Is it just an android thing or can I do something about it? It doesn't really ruin the gameplay in any way, but I'd still like to get it fixed. Any suggestions would help. Thanks.

PowerVR, Android, PPSSPP 1.6.3

Yeah, this is one of the major remaining graphics mysteries. The game uses the depth buffer as a texture for tricks like custom fog, but when I last traced through it that did not seem to be the issue here. A CLUT (color palette) that's used when drawing the glass is black when I don't think it should be. So the game is clearly doing some really nasty tricks that we haven't managed to implement support for yet...

Though, I just realized I haven't tried this in the software renderer for some time, maybe it could offer a clue. Does it work there?

[Gabi1117]

When software rendering is enabled, the game shows the first "Now Loading" screen. And then it's just black after that. I can't see the Namco logo which I know should be there because the guy starts singing. I couldn't get past it either because my OSD has disappeared, which means I can't load my save.

This game also does some other effects where it renders something on a single frame only, and then reuses it. Maybe the thing in the glass was only rendered once, possibly several frames before the glass is even shown on screen?

Here's a GE Dump for fog:

That's #6411, known issue with cheat workaround. Use search before posting Panderer as those two are not related.

Oops. wrong issue

[hrydgard]

The glass in the turtle level is no longer black, for whatever reason.

As for the rest, it's a duplicate of #6411. Closing.
