Use at your own risks. I am not affiliated in any way to Electronic Arts, so the following is pure guesswork. Additional contributors : Ian Brown : the LZ77 algorithm variant used in .QFS files (id 0x10/0x11) ====================================================== PART I : Commonly used data structures and conventions ====================================================== I.1 - Numbering conventions =========================== *** Cars : 0 McLaren F1 1 Ferrari F50 2 Ford GT90 3 Jaguar XJ220 4 Lotus GT1 5 Lotus Esprit V8 6 ItalDesign Cala 7 Isdera 112i *** Tracks : 0 'OVAL' Pioneer Testing Facility 2 'OZ' Outback 3 'PAC' Pacific Spirit 5 'NORT' North Country 6 'MED' Mediterraneo 7 'MYST' Mystic Peaks 8 'MONO' Monolithic Studios (secret track) I.2 - SHPI bitmap directories ============================= SHPI structures are used to pack together several bitmaps, each with a 4-character identifier. The 16-byte header format is the following : offset len data ------ --- ---- 0x00 4 'SHPI' 0x04 4 length of the file in bytes 0x08 4 number of objects in the directory 0x0C 4 directory identifier string (often 'GIMX') This header is followed by the directory entries, each consisting of a 4-byte identifier string, and a 4-byte offset inside the SHPI structure pointing to the beginning of the corresponding data. Each entry in the directory represents a bitmap or sometimes a color palette. There may be gaps between the directory and the first bitmap, and between consecutive bitmaps (significance unknown). Each directory entry points to a bitmap block with the following structure : offset len data ------ --- ---- 0x00 1 7Bh 0x01 3 size of the block (= width x length + 10h) 0x04 2 width of the bitmap in pixels 0x06 2 heigth of the bitmap in pixels 0x08 4 ? 0x0C 2 x position to display the bitmap 0x0E 2 y position to display the bitmap 0x10 w.h bitmap data : 1 byte per pixel Note that value 0xFF in the bitmaps stands for the background : this is useful when a bitmap has to drawn on top of another one. I.3 - LZ77 compressed data ========================== Many files in NFS2 contain compressed data using various versions of a Lempel-Ziv algorithm. ====================== PART II : File formats ====================== II.1 - *.FSH ============ Found in: FEDATA\PC\ART, GAMEDATA\DASHHUD\PC, GAMEDATA\RENDER\PC, GAMEDATA\TRACKS\PC This used to be EA's favorite picture file format in NFS 1, but as pictures became larger and computers became faster it got progressively replaced by compressed .QFS files. These files are plain SHPI bitmap directories (see I.2), usually with identifier 'GIMX', containing various bitmap objects and sometimes a palette. II.2 - *.QFS ============ Found: nearly everywhere This is a compressed version of the .FSH file format, using a LZ77 compression algorithm to reduce the size of files (see I.3). The compressed data id is usually 0x10. The expanded data is a plain SHPI bitmap directory, usually with identifier 'GIMX', containing various bitmap objects and sometimes a palette. II.3 - *.STF ============ Found in: FEDATA\PC\STATS These 527-byte files contain the best times for each track (the text files *.SSF in the same directory are apparently not used at all, they are not updated when new best times are obtained). They contain 31 entries, each of which is 17 bytes long. - The first entry corresponds to the best lap time - The next 10 entries correspond to 2-lap races (best time comes first) - The following 10 entries correspond to 4-lap races - The last 10 entries correspond to 8-lap races. Each entry has the following structure : offset len data ------ --- ---- 0x00 9 player name : null-terminated character string 0x09 2 car type : between 0 and 7 (see I.1) 0x0B 4 time expressed in 64ths of a second 0x0F 2 skill level : 0 for sim mode, 1 for arcade mode II.4 - INSTALL.WIN ================== Found in: root directory This file lists the directories containing the various components of the game (like paths.dat in NFS 1), but is now in text format. Each line contains a 3 character code (a digit between 0 and 4, followed by "rn" or "nn"), immediately followed by the name of the relevant directory. The two first entries code the chosen language ("4nnenglish" if you're like me) and setup type ("4nnlocal" usually). Other Need For Speed 2 cheats hints faqs solutions: 1.
