I don't know what you can do, but I know what I'm going to do and that is close this thread. The Kalisto version of FF9 is an illegal, pirated, copied version. It is well known to have many many problems w/ePSXe. This probably why you are having problems.
Please read the rules posted in the General Discussion Forum. You will see that it is forbidden to talk about any illegal things here, like Kalisto. Doing so can get you banned. But since you are new here I'll let you off with a warning, don't do it again.
