GameINI

You can configure settings per game through their GameINI. GameINI is a plain text file with game's GameID as its file name and INI as its file extension. It can be retrieved from game's properties, right-click the game from game list then choose Properties from the context menu, then click on the Edit Config button and edit the empty text file that pops up. When editing, carefully arranged line, headings, and capitalization are important.

The following entries go under [Video_Settings] section of the GameINI.

Internal Resolution
Values starting from 0 represent the drop down order in the list that dolphin uses.
 * "-1" is a special case that does not exist in the GUI. It is used to set an Internal Resolution that is the nearest whole number multiplier of the value set in Dolphin's general settings, rounded down. For example, if 2.5x Native is set in the GUI (general settings), then 2x Native will be used.
