CTR backup problem!!!

[ragnellalondite]

I recently used CloneCD to back up my CTR disk but when I try to run the backup on the PSX, it doesn't work. I do the swap trick perfectly but the backup always freezes at the SCEA Presents screen. The backup works perfectly on an emulator, though. What should I do?

BTW, my PSX and the ROM are NTSC-U.
