Disc Swapping
 

I just recently beat Disk 1 on FF9 but my mod-chip that I use for playing backup copies of my games is one were you have to put in a orginal playstation disk in first and then put in your backup disk. The brand is game hunter and they moved their website so I am unable to find infomation about it there. Can anyone help me please? I am stuck on disk 1 and can not go to disk 2.
P.S. My dog and cat got hold of the orginal disk 2 & 4 of FF9 in case anyone wondered why I do not just use the orginal)
