Emulator

"Do not exit Dolphin." If this matters, something nasty is happening. (Our BS2 emulation is known to be junk, but this sounds like something else.)

Actually, it doesn't matter. I just hadn't tested doing it the other way until now.

Oh... then it's probably just our garbage BS2 emulation. :) I mean, if someone is really interested, this probably isn't too hard to fix, but it's probably nothing interesting; I would guess we're just skipping updating some cache when we skip the system menu.

Launching game 1, going to the Home Menu (the one you get with the Home button, not the actual Wii Menu), changing the disc to game 2 and then going to the Wii Menu will lead to the same result as following the steps in the issue report. I assume that this rules out Dolphin's code that gets run when launching games from the game list?

Sounds like a bug with the Default ISO override in Dolphin's boot function.

Yes, that rules out something involving BS2 emulation.

Someone should try that procedure on hardware to see what happens.

@skidau: It happens with Change Disc too, so it isn't Default ISO specifically.

@magumagu: I tested it now on my vWii, and it works as expected. The game that is inserted is always the one that shows up. If this bug had been on real Wiis, I think people would've noticed that it could be used to boot games from other regions.

Guessing it has to do with CWII_IPC_HLE_Device_es::m_ContentFile not being set by a boot using the game list. A call to either CWII_IPC_HLE_Device_es::LoadWAD (which might not be an appropriate name then) or DVDInterface::SetVolumeName (or DVDInterface::SetVolumeDirectory...or even DVDInterface::ChangeDisc) at the right time could fix this already; but my random testing in a half-asleep state only got me to kill dolphin in a spectacular way :^)

This also happens when you:

• Set game A as the default ISO.
• Launch System Menu.
• Launch Game A.
• Stop emulation.
• Set game B as the default ISO.
• Launch System Menu.

Game A's banner still shows up in the disc channel.

Are we maybe missing some DVD drive reset command or similar on boot?

I think the Wii Menu just has a cache somewhere that isn't getting invalidated properly.

Almost certainly, but the question is what invalidates this cache on hardware, and when?
