What's the problem? Describe what went wrong.

In the mini-game "Photo Finish" an emulation inaccuracy of the Dolphin Emulator becomes recognizable. One of the two penguins on the right side at the end of the game shows graphic errors.
This problem also occurs when all cheats, hacks and improvements are disabled.

What steps will reproduce the problem?

  1. Make sure the mini-game "Photo Finish" is unlocked.
  2. Start MP4
  3. select "Minigame Mode" in the main menu.
  4. select the mini-game "Photo Finish" and hope that the picture with the penguins is used. If another picture is used, press B and repeat step four.
  5. start the game and play until the end screen comes up.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Yes, 5.0-10121

Is the issue present in the latest stable version?

Yes.

What are your PC specifications? (CPU, GPU, Operating System, more)

CPU: Intel Core i7-8700K @ 4,3 GHz
GPU: I'm a GeForce GTX 980...
OS: Windows 10

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

That looks like the animation is desynced on some of the vertices... can you try using interpreter? Load a savestate shortly before it loads the finish to save time.

#2 Updated by Luis 6 months ago

It also happens using interpreter. But I'm not sure when it loads the finish. I made a savestate right before the "Finish" lettering comes up but I'm not sure if that's too late.

#3 Updated by Luis 6 months ago

I noticed that not always the same penguin is affected. Sometimes both the left penguin and the reflection of the right penguin are affected and sometimes both the right penguin and the reflection of the left penguin are affected.. if that helps.

#4 Updated by JMC4789 6 months ago

Try single core?

#5 Updated by Luis 6 months ago

I never use dual core...

#6 Updated by JMC4789 6 months ago

Haha, always worth a shot. I have a feeling this is a CPU issue.

#7 Updated by Luis 6 months ago

Oh, and I have Revision 1.02 of the game, not 1.01, I just noticed.

#8 Updated by Techjar 6 months ago

Might also be worth testing it on software renderer, though it's abominably slow.

#9 Updated by Luis 6 months ago

I tried that, creating a savestate right before the "Finish" lettering comes up and testing it from there, but the issue still occurs.

#10 Updated by Techjar 6 months ago

Okay, so not a video backend issue.

I can reproduce this with the NTSC-U version (GMPE01 revision 1) which has a handy AR code that unlocks all minigames.
