If you have MV on Steam: C:\Program Files (x86)\Steam\steamapps\common\RPG Maker MV\dlc\KadokawaPlugins
If you don't have it on Steam, the download should be in the email.
i don't have an email ._. i really need the foreground.js but there is no download i can find
Where did you download MV from?
It should be there.
I think it's in the Client Are or something.
seems that a lot of my emails got wiped (i got hacked not to long ago) so i cant get the foreground.js :/
