Problems with SSF

I cant seem to get this program to run properly, when I start it up I get a error message and since I dont know Japanese I cant figure out the problem. I also have the saturn bios in the same folder, but I think its the right one and should work. Any ideas on how to get this to work would be greatly appreciated.
- go to folder message

- edit the file called "default"

- replace "japanese" by "english"

- run another time ssf

- check the error message (now in english)

common problems are :

- display not in 24/32 bit mode

- bios not named "boot.rom"
