Need help with backups on the PSone

[TierZero]

i've had this happen to me with a bunch of images that i grabbed from the net (bubble bobble 2 was one of them).
what worked for me every time was using bootedit and giving the image a new boot sector. not sure why it worked for me, but your comment about the 2 x's on the white screen jogged my memory back to what i did to make it work.

hope that helps a bit?
