How many save files are there in BBS? Is it limited to only 1 Ven file or something like that?

I think you can do as many as u want aslong as u have space

yeah i think you can do what Venterrqua said

I can confirm you can do as many as you want or roughly 1,000 save files ( can't be bothered counting each save file, but I counted more than 100, so i'd assume it goes all the way up to 1,000) aslong you have enough space on your memory stick to do so. This may change in the English release.

 

If they do change it they'll most likely make it so that each characters storys save file is separate. Which is likey, as quite a few players complained of accidentally saving over another characters save file because they're all in one, even I did once and rather than blame it on my idiocy i'd rather blame it on Sqaure-Enixs decision to make each chacters save file on different chacters blocks rather than making it separate.
