FMCB swap trick 007 nightfire issue

[Deagonx]

I know the disk works because other levels boot up fine, but when i select the second level it just stops at a loading screen, what can I do? my ps2 is fat model schp 30001 r

::EDIT::
I made one with cogswap loader because i heard it works with nightfire, and it did, but how do I get it to launch FMCB? does it need to be burned to a CD-R? cause i burned it to a DVD+R, or can i use it to some how launch uLuanchelf?
