Emulator

Try doing the following:

1. Stop the current game if one is running (even if it's Brawl).
2. Start Brawl.
3. Go to Masterpieces and start The Legend of Zelda.
4. Once the game finishes loading and you can see Link, press the Pause button on Dolphin's toolbar to prevent the trial timer from expiring.
5. Open the Graphics window.

Then check that the game config is applying the following settings:

• In the Enhancements tab in the Enhancements group, Texture Filtering should be 1x Anisotropic.
• In the Hacks tab in the Embedded Frame Buffer (EFB) group, Store EFB Copies to Texture Only should be unchecked.
• In the Hacks tab in the Texture Cache group, the Accuracy slider should be all the way to the left at Safe.

Questions:

• Do the settings above have their correct values? If not, try changing them to those values then unpausing the game. Does that fix the issues?
• When launching one of the NES games the Game ID changes from RSBP01 to something else. The new Game ID is the last set of letters/digits in the title bar of the render window; what is it when The Legend of Zelda is running?
• 2515 isn't a valid version of Dolphin, could you double check that?
