CDROM Disk Format |
Originally intended for Mode1 Sectors (but is also used for CD-XA Mode2) Supports "FILENAME.EXT;VERSION" filenames (version is usually "1") Supports all-uppercase filenames and directory names (0-9, A-Z, underscore) For PSX: Max 8-character filenames with max 3-character extensions For PSX: Max 8-character directory names, without extension For PSX: Max one sector per directory (?) For PSX: Max one sector (or less?) per path table (?) |
Uses Mode2 Sectors (see Sector Encoding chapter) Allows 800h or 914h byte data per sector (with/without error correction) Allows to break interleaved data into separate files/channels Supports XA-ADPCM compressed audio data Stores "CD-XA001" at 400h Primary Volume Descriptor (?)

- Directory sizes are always rounded up to N*800h-bytes. - Directory entries should not cross 800h-byte sector boundaries. There may be further directory entries on the next sector after the padding. To deal with that, skip 00h-bytes until finding a nonzero LEN_DR value (or slightly faster, upon a 00h-byte, directly jump to next sector instead of doing a slow byte-by-byte skip). Note: Padding between sectors does rarely happen on PSX discs because the PSX kernel supports max 800h bytes per directory (one exception is PSX Hot Shots Golf 2, which has an ISO directory with more than 800h bytes; it does use a lookup file instead of actually parsing the while ISO directory). |

Short names are uppercase, max 8 chars, without spaces (with "~N" suffix if the long name contains spaces or more than 8 chars). Many folder names are truncated to one char (eg. "D" for Long name "DTex"), in such cases short names CAN be lowercase (eg. "z" for Long name "zTrans"). The Long Names are scattered around in the NAMELIST files in ECTS.WAD file, so they aren't suitable for lookup (unless when loading all NAMELIST's). |

FDLTBL.DAT seems to be used to divide the file list in CDRTBL.DAT into separate folders. The Folder List entries are containing the first file number for each folder. Empty folders have same file number as next entry. The last folder contains the specified file number plus all remaining files. 000h 56h*2 Folder List (16bit File Numbers, increasing from 0004h to 0xxxh) 0ACh 748h Zerofilled 7F4h 0Ah Game ID (ASCII "SLPS1045",00h,00h; always so on Disc 1..3) 7FEh 2 Disc ID (1..3 = Disc 1..3) |
000h 8000h File List (1000h x 8-byte entries) File List entries: 000h 4 Sector (MM:SS:FF:00 in BCD, increasing) ;\all zero for 004h 2 Size1 (NumFramesCh1 or NumSectors) ; unused entries 006h 2 Size0 (NumFramesCh0 or Zero) ;/ The meaning of the Size entries depends on the file type: Normal binaries: [004h]=NumSectors [006h]=0 (1 channel) XA-ADPCM streams: [004h]=NumSectors-50h [006h]=0 (16 channels) MDEC streams: [004h]=NumFrames [006h]=0 (audio+video) Special streams: [004h]=NumFramesCh1 [006h]=NumFramesCh0 (2 channels) To determine the actual filesize, one must compute the difference between sectors for current and next used file entry (or end of CD.IMG for last file; or alternately assume last file to be a Normal Binary with Size=NumSectors). Normal Binaries: Contains single files (file=0/channel=0). Filetypes include TIM, VB, VH, other/custom file formats, and DOT1 archives. The DOT1 archives have 4-byte aligned offsets, but, unconventionally, with some offsets set to ZERO (usually the last entry, and sometimes also other entries): SEQ files (Disc1:Dir08h\File173h) ;with ZERO entries (=uncommon) SEQ files (Disc1:Dir09h\File176h..3D7h) ;with ZERO entries (=uncommon) SEQ files (Disc1:Dir0Ah\File3DAh..3E6h) ;with ZERO entries (=uncommon) TIM files (Disc1:Dir4Fh\File962h..983h) ;with ZERO entries (=uncommon) TIM files (Disc1:Dir0Ch\File414h..426h) ;without ZERO entries (=normal DOT1) XA-ADPCM Streams (Disc1:Dir0Bh\File3E7h..413h): These contain 16 audio streams (file=1/channel=00h-0Fh). The Size entry is set to total size in sectors for all streams, minus 50h (ie. there appears to be 50h sectors appended as padding before next file). MDEC Streams (Disc1:Dir53h\FileBD1h..BEBh): These are standard STR files with MDEC video (file=0/channel=1) and XA-ADPCM (file=1/channel=1). There are 10 sectors per frame (8-9 video sectors plus 1-2 audio sectors). The total filesize is NumFrames*10+Align(8) sectors; the Align(8) might be there to include one final audio sector. Special Streams (Disc1:Dir07h\File0E9h-16Eh and Dir50h\File985h..B58h): These are custom STR files (non-MDEC format), perhaps containing Polygon streams or whatever. There are two channels (file=1/channel=00h-01h), each channel contains data that consists of 5 sectors per frame (1xHeader plus 4xData). The sectors have STR ID=0160h, and STR Type as follows: 0000h=Whatever special, channel 0 header (sector 0) 0400h=Whatever special, channel 1 header (sector 1) 0001h=Whatever special, channel 0 data (sector 2,4,6,8) 0401h=Whatever special, channel 1 data (sector 3,5,7,9) The File List size entries contain Number of Frames for each channel (either of these entries may be zero, or bigger/smaller/same than the other entry). The smaller channel is padded to same size as bigger channel (ie. total filesize is "max(NumFramesCh0,NumFramesCh1)*10 sectors"; though that formula doesn't always hold true, for example, Disc1:Dir50h\FileA2Dh and FileB1Bh are bigger or smaller than expected). |

Y*2Ch Collision info 2? ;/ The ext.hdr mentioned above exists only in some .MOD files (usually in one of the last chunks of MP*.WAD). Files with ext.hdr have N>1, Flags=1 (but files without ext.hdr can also have those settings). Files with ext.hdr do usually have uncommon garbage values at hdr[4], which isn't too helpful for detection. The only way to detect models with ext.hdr seems to be to check if the ext.hdr contains valid increasing entries in range 0..N-1. WAD's that do contain a model with ext.hdr do usually also contain an extra 100h-byte file, that file contains N bytes for model 0..N-1 (plus zeropadding to 100h-byte size), the bytes are supposedly redirecting models without Data Arrays to some other data source. The 100h-byte files don't have any header or checksum, they contain up to 9Ch entries (so there's always some zeropadding to 100h), the existing 100h-byte files contain following values in first 4 bytes (as 32bit value): 04141401h, 0C040017h, 01010101h, 09030503h, 0A0B0A0Bh, 03020102h, 0C060900h, 00060501h, 04040201h, 01010203h, 01030201h, 05000302h, 0C040317h, or Zero. To distinguish from other files: BIN/MAP files start with a 4-byte aligned Size value; if Size=0 or (Size AND 3)>0 or Size>RemainingSize then it's probably a 100h-byte file. Best also check if last some bytes are zeropadded. Exceptions: Retail MP090..MP100_*.WAD has model with ext.hdr, but no 100h-byte file Demo MP041_00.WAD has model with ext.hdr, with zerofilled 100h-byte file Note: Some models have ALL models listed in ext.hdr (which is about same as not having any ext.hdr at all; except, they ARE bundled with 100h-byte file). |
Some (not all) MP*.WAD files are bundled with MP*.DEM files, supposedly containing data for demonstration mode. There are two versions: demo version: size 2584h (9604 decimal) (some files with partial checksum) retail version: size 0E10h (3600 decimal) (without checksum) |

Each pack chunk contains the following: * 3 Huffman trees (one for literal data sizes, one for distance values, and one for length values) in the bit stream. These consist of: o A 5 bit value for the amount of leaf nodes in the tree o 4 bit values for each node representing their bit depth. * One 16 bit value in the bitstream for the amount of subchunks in the pack chunk. * The subchunk data, which contains for each subchunk: o A Huffman code value from the first tree in the bit stream for the amount of literals in the byte stream. o Literals from the byte stream. o A Huffman code from the bit stream that represents the distance - 1 of a distance/length pair. o A Huffman code from the bit stream that represents the length - 2 of a distance/length pair. |
