sorry but thats wrong ;-; in one of my old saves i named my character "shiro" and it saved , when tyson was serious and he said my name "Shiro" not Dave ;-;. But for some reason when i started a new route it doesnt save now
No, it's not wrong. A few updates back a change was made to the earlier days where that was edited (I think it was 5 updates ago?). But because I knew a bunch of people had old saves, I've been supporting that in-code so it's not strange. Any new saves you'll be forced into having "Dave", but if you have old ones you'll be able to use the name you picked then.
