"fun value" is a number which triggers certain events in the game, for example, sans spawning there from this, etc. the number is basically random and can make random events happen that doesn't usually happen like "the wrong number song" or, "alphys ordering a pizza."

to get to it, you will need to use the app "run" on your computer, and type in "AppData"/"%AppData%" without the quotes, go to the local folder, then find "UNDERTALE." go in, and you will see a couple files, in which file0 and undertale.ini contain the fun value.

what you need to do here is head to this list

then what you need to do is:

1. in the undertale.ini file, which is responsible for persistent events (though certain values change), look for the word fun, then enter the value shown in the list, save from notepad, then open the game.

2. if you want a SAVE point to have a certain fun value (so you can open undertale and have that fun value triggered immediately [would still need undertale.ini's persistent data]) on notepad, head to line 36 in the file and change the number to that on the list.

hope that helps =3
