At first I thought this meant that I just had to keep the copyright notice inside the source files, but apparently it means I have to include their notice somewhere as a separate file along with my game(s).
But our game is for PlayStation Vita, so that is obviously impossible.
It is also impossible to show their MIT copyright text inside the game anywhere.
Do I simply have to not use the MIT-licensed code or are there other options etc.?
