iso.bin structure (decrypted)

All offsets are in little endian (except in the last table where there are two counters in decimal) 

1 block = 1024 bytes (0x400)
1 cluster = 16 blocks = 1024*16 bytes =16384 bytes (0x4000)

Disc map table

iso.bin Disc map table

The table has an area reserved of 1032192 bytes. Divided in 32256 entries, of 32 bytes each entry. The number of used entryes in the file_table can vary (seems to be dependant of the .iso contents). The number of entries availables to store data is affected by a checksum (16 bytes) that is present only in the the last block of each cluster (in block nº16 of every cluster) When this checksum is between used entryes... his length is 32 bytes (it "steals" the area of one entry) Seems to be a checksum of this block... when the block is filled with zeroes the checksum is : 1CCE0033 60C6E8A6 B36A972D 00EAFDBF

The first 4 bytes of each entry (file offset from start of .iso root) increases for each entry in a amount of bytes determined by the previous entryes.... in other words... the second file in the .iso is displaced the number of bytes used by the first file... and the third file is displaced in a amount of bytes used by the addition of the sizes of first and second file

Entry Nº Offset Length Name Example Notes
1 0x00 4 bytes (0x04) file_offset 0 file offset from start of .iso root (for the first entry is always 0)
0x04 2 bytes (0x02) file_size variable this size determines the displacement of the next file (in the next entry)
0x06 2 bytes (0x02) file_type ? 01 00 usually 1... and 0 for the last entry
0x08 16 bytes (0x10) file_checksum ? variable unknown
0x18 8 bytes (0x08) padding
Up to 32256 same structure than the previous entry

iso.bin Common Disc table

Composed by a variable number of entries (depends of the number of files/folders inside the discs), 12 bytes each entry

Entry Nº Offset Length Name Example Notes
1 0x00 4 bytes (0x04) file_offset ? 0 always increases
0x04 2 bytes (0x02) file_type ? 01 01 always 01 01
0x06 3 bytes (0x03) counter 1 some kind of counter, in decimal, always increases <-------- related with "sectors" inside the .iso ?
0x09 3 bytes (0x03) counter 2 another counter, in decimal, always increases, its in relationship with the previous counter (this one is always 200 bytes bigger than the previous one)

There are 2 "special" entries to mark the "start of a disc" (FFFFFFFF 00000000 FFFFFFFF), and the "end of a disc" (FFFFFFFF FFFFFFFF FFFFFFFF). Between the start and the end, there are a variable number of entries.

There is also an added string at the end of the last disc (after the last FFFFFFFF FFFFFFFF FFFFFFFF entry)... is a 40 bytes unknown area (in my example my game had 4 discs so maybe this area is divided in chunks of 10 bytes for each disc)

So as an example... for a game with 4 discs this table is:

  • first entry of disc 1 ---> FFFFFFFF 00000000 FFFFFFFF (start of disc 1)
  • next entries of disc 1 --> data from disc.... the number is variable
  • last entry of disc 1 ---> FFFFFFFF FFFFFFFF FFFFFFFF (end of disc 1)
  • first entry of disc 2 ---> FFFFFFFF 00000000 FFFFFFFF (start of disc 2)
  • next entries of disc 2 --> data from disc.... the number is variable
  • last entry of disc 2 ---> FFFFFFFF FFFFFFFF FFFFFFFF (end of disc 2)
  • first entry of disc 3 ---> FFFFFFFF 00000000 FFFFFFFF (start of disc 3)
  • next entries of disc 3 --> data from disc.... the number is variable
  • last entry of disc 3 ---> FFFFFFFF FFFFFFFF FFFFFFFF (end of disc 3)
  • first entry of disc 4 ---> FFFFFFFF 00000000 FFFFFFFF (start of disc 4)
  • next entries of disc 4 --> data from disc.... the number is variable
  • last entry of disc 4 ---> FFFFFFFF FFFFFFFF FFFFFFFF (end of disc 4)
  • unknown area of 40 bytes (10 bytes for each disc ?)

Notes

  • You can decrypt any eboot.pbp from a mini OR pspremaster OR psn paid eboot(?) with npdpc
  • You can use any header on an iso.bin, and the ps3 won't even try to check it
  • (be) means that the generated table values will have to be endian swapped when using npdpc (now possible thanks to arnold)
  • [arnold's code]
  • [kirk lib]

About PS2 Classics

There are some new formats present in PS2 Classics. The first one is ISO.BIN.ENC, the second one is .dxt, which is inside CONTENT folder and there's also a single file named CONFIG. You can see more about this when you first install a PS2 Classic. There's also a problem with the Data while trying to execute the instalable file. The message Unsupported Data appears on the screen when highliting the file and the error 80028F14 is shown while trying to start.

This was made with the Max Payne game. There could probably be other formats present aswell
