This guide will teach you how to quicksave/quickload.

First of all, head to directory that looks like this C:\Users[Your username]\Documents\Harry Potter II. Search for "User.ini" in this folder then open it up. Scroll down and then you will see butons and their functions (Example "1=). All you got to do now is just find buttons that is most convinient for you (for me it's f2 and f3) and fill empty line after equals symbol with words "savegame 0/loadgame 0". In my case it will look like this f2=savegame 0/f3=loadgame 0

That's it! I hope this helped you a lot. Good luck setting new world records
