Dolphin IL emulater help!

Where do I save the ISO files to where I can access them on the emulater? Is there something wrong with my emulater? Do I need to configure anything to get it to work?

https://www.romulation.org/forum/index.php?topic=26791.0I would advise you read this.Also, If I remember from my time with it, they can be anywhere, you just point the emulator towards where they are placed, using the "load" function or try dragging the iso into the white blank space when you open the program...But that tutorial would be better since I haven't used the program in months.
