I really need to ask what in the world is INI? On Dolphins site there is games or something like that and there is only ini. And here in the forums are ini. What that ini mean? Is it somekind of update to Dolphin? How it works?
INI is short for and initialization/configuration file. It has an .ini extension. Usually they contains settings for a particular program (in this case, the settings for Dolphin and it also contains specific settings for specific games).
