We have 1024 possible battle numbers: 0 - 1023. Each group of *4* Battle Numbers refers to a
particular Scene file: for instance, Battles 0-3 refer to File 0 in Scene.bin, Battles 4-7 refer to File 1 in Scene.bin, and so forth.

It's Its structure and opcodes are described [[FF7/Battle/Battle_Scenes/Battle_Script|here]].
NOTES:
*A monster's total AI size will always be an even number of bytes. If the actual scripts are an odd number, a single NULL (FFh) will be placed before the next monster's AI header (may not be required).
*Battle begins after all characters' Initialize scripts have been run (order to be determinedPlayers first, then enemies, then formation).*Party Member Death The only character with "Battle End" is only used on in Cloud's AI. It's meant to lower the character's Love Points with him if he lets them die or he dies with them in the party (not sure which). Script never seems to activate on other characters and may not even execute on Cloud's.*PostPre-Attack Action Event occurs immediately after on all battle participants prior to any character performs actions performed by any attack to any target participant regardless whether damage is dealt of actor or target. This includes all executed 92 commands that have a command index of less than 21h. If any 92 commands are called in this section, the command that caused this script to run has priority.*The Custom Event sections are notcalled by any event. Script owner can be flagged as dead and They only occur if they are called with the 92 command. 60 22 <- command index "Run script" 60 0X <- where X is the script section in hex (eg. X = 8 would still activate. It's priority call Custom Event 1 since it is higher than that of other Counter Scripts.script id 08 [not to be confused with offset]) 92 *Post-Battle Custom Event 8 is only used on Mystery Ninja (all), Ultimate Weapons in location other than above Cosmo Canyon, Safer Sephiroth, and the final "showdown" between Cloud and Sephiroth. These characters have scripts on them that do not remove them from battle when they are defeated. This Script section is used to remove them from the battle probably to clean up memory. Executed after "victory dance"*Custom Events 1-7 may not work.(not thoroughly tested)*The order of scripts executed after an attack ::*Beginning of battle::Pre-Battle (all participants):*Once a "main-script enabled" enemy's time gauge isfull:::Main (Enemy performs action):*Pre-Attack (If enemy script uses a 92 command with a command index of 20h or less)::Pre-Action Setup (occurs on all participants):*#Post-Attack:*#Death Counter (If script owner died, execution stops here):*#General Counter (If script owner was targetExecuted by all targets):*#Physical Counter/Magical Counter (Executed by all targets depending on damage type):*Battle ends::Battle End (all participants)
==== Binary "Cover Flags" ====
The battery cap on left in row 2 covers the left two in row 3 because it shares flag 0x4 with the one in the middle and flag 0x2 with the one on the far left. As long as it is active these in row 3 cannot be targeted.
Similarly, the battery cap on the right in row 2 shares the 0x4 flag with the middle of row 3 and the 0x8 flag with the far right of row 3 so these cannot be targeted until the right side of row 2 is defeated.<br />
It is also necessary to note that because row 1 does not share any flags with the extreme right and left of row 3, they can be targeted if the corresponding enemy in row 2 is defeatedeven if the row 1 enemy is still active.<br />
Also of note is that enemies in the same row that share cover flags are not considered.<br />
Only the first five bits may be considered even though the value is stored as a word.<br />
