Sonic Jam Yabause

I downloaded Sonic Jam USA (NTSC) and I cant seem to emulate it on yabause. It says "Cannot initialise game".
what am I doing wrong?
note: when I downloaded it I got an unpacker, I ran the unpacker and got a .bin file. I renamed the .bin file to .bin.iso hope that helps.
note2: I'm using yabause V 0.9.10

do you have bios?

I think so. I've played two other saturn games already on it, and they worked. I'm going to retry the installer.
