How do I make a file selection menu like Zelda 64 & Mario 64?

I tried finding this on youtube or google but can't find a Unity 5 tutorial?

What I am trying to do is make a file selection menu with 3 files of starting the game. Each file has a separate playerpref values like most games would have? But I have no idea how to do this? It's like someone wants me to not add this feature to my games?

Maybe my own search filter is made this happen?

Any idea's where I can find tutorials of file selection?
If not? How do I code a file selection menu screen like Mario 64 and Zelda 64 for Unity?..

Very much appreciated.

Here is an example of what I am talking about.

 

If you use PlayerPrefs to store the data, then add some checkboxes for "game files" and use check box names as key prefixes for player prefs, like a "FileA_PlayerLevel" instead of simple "PlayerLevel".
And if you use file to save/load player progress, use

Code (csharp):

1. System.IO.Path.Combine(Application.dataPath, <checkbox_name>, <file_extension>)

to load that file.

 

I am a little bit confused? I have no idea where to put this in my code? But I did made 3 of the same scripts only named A, B, and C at the end of the name of the script. So when a player selects file A the player has a script named PlayerScriptA. Scripts B and C checkboxes are off for game file A.

But when I clear playerpref keys it deletes all data even PlayerScriptB and C?
What should I do? : /

here's my code:

Any idea's
most importantly, what's the search name for YouTube tutorials for "File selection menus in Unity"? I tried to search for an hour but can't find any? : /
