Power Stone Collection - Missing Arrow / Gem Locator (depth testing related?)

[Avastia]

The arrow that locates gems on the mini-map does not display properly.
Using PPSSP 9.8-1088, default settings.

Has it ever worked properly? It's hard to tell in the screenshot - is it there and just pointing the wrong direction?

-[Unknown]

[Avastia]

I know in-game there are 2 options for the mini-map. One option shows the gems on the mini-map (that works) the other is an arrow that points to the gems on the field (not working). I haven't tested the game extensively in the past, but I can tell you that in this video PPSSPP vers. 8.1 had the same problem: https://www.youtube.com/watch?v=NfrYzDZvAwg&feature=player_detailpage#t=101

[Avastia]

Add-on from previous post:

The two options are Arrange (the arrow) and original (gems). Below is with Original Gem Locator on in the options menu in-game.

Has anything changed here?

Can you try using the GE debugger to see what's going on when it is drawing in that area? Is it ever drawing a shape that looks like an arrow there?

Thanks for the link on how to use the GE debugger (this thing is amazing!). I've taken a screen shot or where-a-bout the triangle is supposed to appear. I played with the settings in ppsspp (direct3d9, opengl, buffed, non-buffed...) and none of them displayed the arrow.

Please note I am playing this on my Windows 8.1 computer with the latest ppsspp-v1.0.1-159. If you need more info, let me know as I get notifications via email for this issue.

Here is the video of the arrow in action on a PSP: https://www.youtube.com/watch?v=Cq2pgPU_Y_k&t=79 (Go to 1:22)

Can you copy and paste the other tabs when it's just right there?

As far as I can tell, the texture has some data in it under the red - if you double click it, it will zoom, and you can drag it around to be sure. And the red on the right side is highlighting the right area, so it should draw.

That means this is probably an issue with either depth, stencil, blending, lighting, or it's related to that mysterious but rare "things float in the wrong places" bug we still haven't been able to track down. The "Settings" and "Lighting" tabs will show me what the game is doing with those things, to narrow it down.

For example, maybe it's doing a ">=" depth test, which might make this the same issue as Phantasy Star Portable.

Also, there's a "software renderer" option (at the very end of the graphics settings.) It will be very slow, but if that displays the arrow then at least it's not something super weird. I recommend taking a savestate when on that screen, switching the software rendering setting, and then loading the savestate, so you don't have to deal with the slowness.

[Avastia]

It does show up in software render on the bottom of this screen shot. Below I'll have the GE Debugger screen with a zoom on the arrow, as well as the copied/pasted data. Thank you for taking the time to look into this, I (and I'm sure many others) appreciate it unknown.

@hrydgard I don't know much about fog. Is that fog value unusual? It looks unusual (99998320493394448000000000000000.000000.) I don't know if the debugger is showing it correctly, but it should be...

Anyway, it's also using a >= depth test. To just make sure it's not that, go back to software renderer off, and step there in the GE debugger right when it's about to draw the arrow.

Then go to the Flags tab, and double click "Depth test enable". This will turn the depth test off.

After that, click "Step Draw". If the arrow appears (on the right side preview), that means it's something to do with depth testing. If it doesn't appear, everything else looks legit so my money's on fog for now.

[Avastia]

Followed the steps previously mentioned, arrow appears on the mini-map. Zoomed in (accidentally) for a better visual.

[ppmeis]

Tested with latest build. There's no arrow in radar.
