By [RO]man, this is a tool for unpacking the PS3 update package 1.10 available for download from jp.playstation.com/ps3/update/

Quick & dirty, src included, BIG endian structures/files, only for devs, etc...

SCE format is now interesting; we've seen it mentioned in PSP loader, haven't we? ... and the semi-encrypted ELF

Enjoy,
