Phanasty Star zero black screen

I'm playing PSZ on my R4 version 1.24(beta). It plays well but when I get to the first boss the screen turns black as soon as I enter the telporter. Can any one help me with this.

I use this and it works fine. Are you talking about the dragon boss?

I can't tell. The black screen is before I even see the boss. I'm using the romulation english game. If that does work is there a way to change over my save?
