Help with .pbp files (game related)

Hi guys, great site, ( THANKS STAXX FOR RECOMENDING THE SITE)
this is my first post here and i hope its in the correct section.

I have several games for the psp that when i downloaded them they came down in .pbp file, i tried magic iso to convert them but once converted the psp wouldnt recognise them?
Any help greatly appreciated, the games are mainly final fantasy games.

Thanks in advance

theyre ps1 games correct?

eboot.pbp and keys.bin...you create a folder (name it anything you want) and throw your eboot and keys into that folder. You then take the folder and place it into your GAME folder (not game150 or game5xx)

Then go back onto your psp screen and it should show under game > memory stick

Let me know if that helps.

top banana buddy, spot on, yes they were ps1 games, thanks for your help once again:)
