est files contain special effects. They can start to be decoded by using Bayonetta est.bt. Example for wp0000.eff of wp0000.dat of Bayonetta:

• 1.est
• 3.est
• 5.est
• 7.est

contain the gun's jewel sparkles, each file corresponds to one of the guns and contains both sparkles (left and right of the gun), in a different structure (see bayonetta est.bt). At offset 0x108 of this structure you can find the color of the first sparkle as a rgb value of 3 floats followed by an intensity. At offset 0x54 the position relative to the bone, and at offset 0x19 the bone it is attached to.

files:

• 0.est
• 2.est

Contain the fireflash when shooting with x, the aura around the gun when shooting with x, the shell decals when shooting with x, plus one unknown effect.

Effect Management

To the best of the available knowledge, effect are loaded on a per effect file basis, and should be referenced by their number. On way the game triggers effects is by using effect tracks of seq files which are associated to motion files.

This means that, provided an effect file is executed at the chosen moment, nothing prevents adding new effects inside the file. Example on the previously mentioned gun sparkle (file 1.est) where you can add other sparkles to the effect:
