[edit] Eboot.PBP

Selection window

Used on PSP (PSP remaster and PSN content:PS1 classic & Minis), to be loaded with build in PSP emulator on PS3. See: Emulation page

With PSP remaster game, you can select either to start the game directly or the NPJA0040/USRDIR/EBOOT.BIN (Ad-Hoc Party folder). An ICON of the game is also loaded on the top left corner on the menu.

Used also for PSP FW from PS3 internet browser (http://www.jp.playstation.com/psp/update/ud_03.html) correct link if available in English) to transfer on PSP or external storage device.

[edit] Header and filetable

Offset Purpose
0x00 The PBP signature, always is 00 50 42 50 or the string "<null char>PBP"
0x04 Unknown purpose, possibly the version number. Currently is always 0x00000100 or 0x01000100 (some MINIS, PSP remaster and PSP PlayView)
0x08 Offset of the file PARAM.SFO (this value should always be 0x28)
0x0C Offset of the file ICON0.PNG
0x10 Offset of the file ICON1.PMF or ICON1.PNG
0x14 Offset of the file PIC0.PNG or UNKNOWN.PNG (Value can be repeated)
0x18 Offset of the file PIC1.PNG or PICT1.PNG
0x1C Offset of the file SND0.AT3
0x20 Offset of the file DATA.PSP

[edit] PARAM.SFO

Basically the information file for the .PBP - has title, parental control level etc

Fews parameters inside different type of .pbp (psp remaster, psp game, minis, ps1 classic..)

For the external PS3 SFO, see the param.sfo page. Some parameters such SAVEDATA_DETAIL related but used separately from the eboot.pbp as well.

  • Note: this "identifier" seems to be separated in: 8 + 4 + 4 bytes:
For PS1 Classic the last 4 bytes give the size of the first part of the PSAR,
which also means it's the offset (DATA.PSAR file) for part 2 (string as: STARTDAT)

  • PSTITLEIMG000000: Not present on all PS1 Classic and followed also by 4 bytes giving length of first part. After one .pgd part and padding, "PSISOIMG0000" + 4bytes as 00.
