What's the problem? Describe what went wrong.

The Mii Faces on the banner for the Wii Fit channel (next to "last played") and the graph and Mii faces on the opening screen fail to render, leaving a blank space.

What steps will reproduce the problem?

First, set up the Wii Fit channel. You also need to have a Wii Fit account, so it may be easiest to do this on console and then take a NAND dump (note that everything works correctly when loading from a NAND dump; it's only when the faces are generated on dolphin that things go wrong).

  1. Insert the Wii Fit disc
  2. Click the settings button
  3. Select "Install Channel"
  4. Follow the prompts, and return to the Wii Menu

To actually reproduce the issue:

  1. Start Wii Fit or the Wii Fit Channel once (to capture Mii faces and such; this does not happen immediately after installing it IIRC)
  2. Return to the Wii Menu
  3. Observe that the channel banner is missing the Mii faces
  4. Select the channel
  5. Observe that the graph and Mii faces on the opening fail to load (on console you should get something like this. If there is no empty space where a graph should be (like this), Wii Fit decided that there was not enough data to display (this probably happens when you just created an account).

Is the issue present in the latest development version?

Yes, 5.0-10912.

Is the issue present in the latest stable version?

Not tested, as channel installation apparently was not functional until 5.0-1837.

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

  • CPU: AMD A6-340M APU with Radeon(tm) Graphics, 1500 Mhz, 4 Core(s), 4 Logical Processor(s)
  • GPU: AMD Radeon HD 6520G
  • OS: Windows 10 Pro (Insider preview) 10.10.18362 Build 18362

Is there anything else that can help developers narrow down the issue?

EFBToTextureEnable = False or DisableCopyToVRAM = True in the config for Wii Fit at load time seems to solve the problem. Enabling or disabling dual core does not seem to affect it.

I have performance concerns with this. EFB2RAM is rather taxing and what it fixes is rather small.

I think this is a INI note + Wiki note maybe?

Actions #2

Updated by pokechu22 about 2 years ago (I've also added info to the wiki in both the main and channel pages, since EFB2RAM must be used for both as they both generate the images used by the channel)

Unfortunately we have a report that this fix breaks various mini games, so we may want to reverse it. Though a more appropriate fix would be to determine what causes the errors / hang with EFB to RAM.

This didn't actually do anything. We just put a comment in the INI.

It sounds like that may be a recent regression.
