I read that YSM09.12.05 is the latest. I think right now I have YS Menu v1.23. I cannot get Chrono Trigger DS to work so I figured its time to upgrade again. Went from 1.13 to 1.18 to YS Menu v1.23. So just download the latest YS Menu I mentioned from Dec 5, 2009 and copy those files over to the DS overwriting the other ones?
