Eboot.PBP

ICON0 eboot.pbp FW 6.60

Eboot.PBP

Menu screen bin for PSP Remaster located in PSP_EMU

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

When an PSP remaster game is started, you can select either the game or launching the NPJA0040/USRDIR/EBOOT.BIN (original :Ad-Hoc Party folder). An ICON of the game is also loaded on the top left corner during 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.

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
0x24	Offset of the file DATA.PSAR

Then the file PARAM.SFO starts (at 0x28)

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)

For PS1 classic, offset .SFO should not be variable on eboot.pbp.

(e.g.: Title of the game should start at offset 0x358 with category: ME, not as EG)

DATA.PSP

More information, except more targeted at the executable portion (contains info such as ELF size):

Boot & Warning image:

Logo screen from eboot.pbp

• :

Other

• When the eboot is signed as free demo (PSP 6.60 OFW might block it, 6.39 no)

DATA.PSAR

The bulk of the EBOOT, and the portion which contains the executable code.

Offset	Length	Name	Description
0x00	16 bytes (0x10)	magic	: NPUMDIMG (4E 50 55 4D 44 49 4D 47 03 00 00 01 10 00 00 00) (used also on PSP game) : PSISOIMG0000 (50 53 49 53 4F 49 4D 47 30 30 30 30 xx xx xx xx) See PSISOIMG0000 See Iso.bin.edat_Disc_map

:

• 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.

• PGD:

For PGD on JPCSP: http://www.emunewz.net/forum/showthread.php?tid=3834

Offset	Length	Name	Description
0x400	4 bytes (0x4)	magic	PGD
0x404	4 bytes (0x4)	unknown	01 00 00 00

0x40C	4 bytes (0x4)	unknown	00 00 00 00
0x410	unknown	encrypted

• STARTDAT :header contain the header size (50) and .png size (e,g,:"A5 2F" when similar MINIS Warning logo or 06 26 for PSP remaster).

Last part is other .PGD section

PARAM.PBP

PSP XMB referenced it as "game data". Used by: PlayView.

Offset	Lenght	Value	Notes
0x00	4	00 50 42 50	The PBP signature is similar than eboot.pbp
0x04	4	01 00 01 00	Unknown purpose, possibly the version number. Currently is always similar (also on 1.00 or 1.02 disc_version)
0x08	4	28 00 00 00	Offset of the file PARAM.SFO (this value should always be 0x28)
0x0C	4	DC 01 00 00	Offset of the file ICON0.PNG 144x80 (similar since same parameters are used)
0x10	4	xx xx 00 00	Offset of the file ICON1.PNG 310x180 ("information")
0x14	4	xx xx 00 00	repeat Offset of the file ICON1.PNG
0x18	4	xx xx 00 00	Offset of the file PIC1.PNG 480x272 ("Background") not all Playview have it (and so, offset second part)
0x1C	4	xx xx xx 00	Offset second part of the file
0x20	4	xx xx xx 00	repeat second part of the file
0x24	4	xx xx xx 00	repeat second part of the file

Then the file PARAM.SFO starts (at 0x28) with following parameters (see above for length or purpose):

• BOOTABLE: 00 00 00 00

• CATEGORY: "MG"

• DISC_ID :

• DISC_VERSION: "1.00" , "1.02"

Then the ICON0 (should) start (at 0x1DC)

ICON0 &PIC1:

After the 2 or 3 .png, the second part of the file start (is always 0x20).
