			Replays are the sequence of the scenes and actions recorded and stored in the <code>replay.rep</code> file. In GTA San Andreas, this file is located in the 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: End of scene\|Block 8]].

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: End of scene\|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).

'''Replays''' are the sequence of the scenes and actions recorded and stored in the <code>replay.rep</code> 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: End of scene| 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: Vehicle1====
size 52 bytes

====Block 2: Vehicle2====
size 56 bytes

====Block 3: Player data====
Common information about player ped.

OFFSET TYPE DESCRIPTION

0x01 byte index (handle?)
0x02 WORD modelID
0x04 byte [[ped type]]
0x05 byte[3] (align)
0x08 (end)

====Block 4: Ped====
size 52 bytes

====Block 5: Camera====
size 88 bytes

====Block 6: Day time====
This block contains information about current day time during a scene.

OFFSET TYPE DESCRIPTION

0x01 byte[3] (align)
0x04 DWORD timer
0x08 (end)

====Block 10: Unknown====
