Hi, I just found a new glitch that by using it you can finish the game super quickly. Using this glitch you can duplicate items and transfer items between save files. This glitch also works on your party members. This means that you can start the game with the best gear and save a lot of time by defeating enemies fast and ignoring the items. This is how you perform the glitch:

If you have any questions about it just ask me. (the negative side effect of this glitch is that it preduces a loud sound every time you click the mouse)
