Problem running mario galaxy 2

[Collin Hughes]

I have been having problems with getting wii games to work on dolphin, and i would like some help figuring it out. my theory is that my iso might just be bad, but im not fully sure. when i set the iso directory to the file with my iso, the game, being Super Mario Galaxy 2 appears and where the image for it is supposed to be is a grey x. the state has 4 stars next to it, and when i hover over that it says "^ Playable : Needs Efb Access from CPU." im not fully sure what it means, but when messing with the emulator settings i just got the same result. when i loaded the game, i get a bunch of errors, to the point that i just need to use task manager to close out of it. the first error i always get is "Failed to write BT DINF to SYSCONF". again, i have no idea what that means. the next error reads "SetupWiiMemory: Can't create setting.txt file". the third error i get is "Unable to resolve read address 80004000 PC 0" and after that it is just the same messages with a different number at the end. i have had no problem emulating Super Mario Sunshine in the past, so i dont know what i should do. i think my computer may just be bad, it has been falling apart for a while. you can find all the information you need about my computer on my profile if needed. thanks for your time and help!

Wii games are like that until you save in them at least once.

Update to the latest dev build, go to Graphics > Hacks > Embedded Frame Buffer (EFB) and disable Store EFB Copies to Texture Only. Yes, Dolphin does say to leave this checked, but some games do need it to be unchecked (but games that don't need it are slower when it's on, and many games don't need it, which is why it isn't on by default)

"Failed to write BT.DINF to SYSCONF" and "SetupWiiMemory: Can't create setting.txt file" means Dolphin isn't able to write to Documents. Check the permissions of the Dolphin Emulator folder in Documents.

First, the setting to disable for the Super Mario Galaxy games is Skip EFB Access from CPU, not Store EFB Copies to Texture Only. Second, Dolphin disables it automatically (though it only does so robustly if you're using a recent development build), so there isn't really any point in doing it manually.

But having the wrong value for this setting wouldn't prevent the game from starting, it would prevent you from using the pointer correctly in certain situations.
