I looked on the wiki for Metroid Prime 2: Echoes and Metroid Prime 3: Corruption, and it says that at an IR greater than 1x, there will be some kind of dot in the middle of the screen. Is there a way to change the IR in an individual game's settings (Right-click on a game->Properties), and if not, would it be possible in a future Dolphin update? It's not like it bothers me or anything; I'm just curious if there's a way to override whatever the IR is set to in the main graphics menu.
