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

Usually every .PBP embeds a PARAM.SFO file and PARAM.SFO file starts at offset 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 PARAM.SFO. Some parameters such SAVEDATA_DETAIL related but used separately from the eboot.pbp as well.

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.PSAR

The bulk of the EBOOT.PBP, 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

See PGD wiki page on PSP Dev wiki.

• 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 another .PGD section.

PARAM.PBP

PSP XMB referenced it as "game data". Used by: PlayView､ DLC/add on.

Offset	Length	Value	Notes
0x00	4	00 50 42 50	Magic (".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 or ICON1.PMF 310x180 ("information")
0x14	4	xx xx 00 00	repeat Offset of the file ICON1.PNG or ICON1.PMF
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

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

• BOOTABLE: 00 00 00 00

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