Replays are the sequence of the scenes and actions recorded and stored in the replay.rep
file. This file is located in the GTA San Andreas User Files directory.
Format Details
Each .rep file consists of a header string and variable amount of 'scenes' (or 'frames'). A scene is a copy of important game information at given moment of time (actors, vehicles positions, weather, clothes, etc). Following one after another, the scenes create an illusion of a movie when played. The most of scenes contains a same set of blocks and ends with Block 8.
The .rep file itself consist of a header string which is simply the text GtaSA29 and up to 8 parts, size of each one is 100,000 bytes, depending on the replay length. So, the maximum size of a replay file is 800,008 bytes (including 8 bytes of the header string). If the replay length is that it does not match 100,000 bytes boundary being less, the rest of the file is filled with useless data (commonly the previous replay data).
Data Blocks
Each block consists of a byte denoting its type and some data as described below. A number in a block name is the data type stored in the first byte of the block. Reading this byte, the game detects what block follows.
Block 0: End of file
This block denotes the end of replay data. It consists only of a data type. After this block the game stops reading the replay file.
OFFSET TYPE DESCRIPTION 0x00 byte data type (0x00) 0x01 (end)
Block 1: Vehicle
size 52 bytes
