While using a PSP screenshot plugin, it added a folder in PSP/SCREENSHOT/XMB/ for XMB screenshots (there is another folder, not yet tested, for in-game screenshots) and a file PSCM.DAT which has the ".PBP" file signature (00 50 42 50 in hex), like EBOOT.PBP. It seems to hold a PNG as a thumbnail for the pictures folder.

See if this is actually related to PBP
Try to understand its meaning and usage
