Diamond/Pearl Version

If this attack is successful and user’s original species is Chatot, this attack has up to a 31% chance of confusing the target depending on user’s cry.

Flag b: The target can use Protect or Detect to protect itself from this attack.

Detailed Information

Each Pokémon in the player’s party can have a recorded sound which is 1000 bytes long. The sound’s format is 4-bit PCM, where two samples are stored in a single byte (where the first sample is in the low 4 bits, the second sample in the high 4 bits). When the game records a Pokémon’s sound, it collects 1,984 8-bit samples of microphone input at a rate of about 2000 samples per second, adds 16 zero-bytes, and then converts the resulting 2000 bytes each into a 4-bit sample as follows:

-128 → 0; -127 to -112 → 1; -111 to -96 → 2; -95 to -80 → 3; -79 to -64 → 4; -63 to -48 → 5; -47 to -32 → 6; -31 to -16 → 7; -15 to 15 → 8; 16 to 31 → 9; 32 to 47 → 10; 48 to 63 → 11; 64 to 79 → 12; 80 to 95 → 13; 96 to 111 → 14; 112 to 127 → 15.

The game sets a variable, X, to the 16th byte (counting from 1) of the recorded sound, and thus near the beginning. If the user is a Chatot and Transform isn’t in effect for the user, Chatter has a certain chance of confusing the target as follows:

• If X is greater than or equal to -30 and is less than 30, or if the user has no recorded sound associated with it, the confusion chance is (0+1)%.
• If X is less than -30, the confusion chance is (10+1)%.
• If X is greater than or equal to 30, the confusion chance is (30+1)%.

The confusion effect is considered an additional effect for the purposes of Shield Dust, but not for Serene Grace.

Black/White Version

May confuse the target. Additional effect won’t occur unless user is a Chatot and hasn’t transformed. (Considered an attack with an additional effect.)

Flag b: The target can use Protect or Detect to protect itself from this attack. Flag k: This is a sound-based attack. Flag n: This attack can even target a Pokémon that isn't adjacent to the user.

Detailed Information

Each Pokémon in the player’s party can have a recorded sound that is 1000 bytes long. The sound’s format is 4-bit PCM, where two samples are stored in a single byte (where the first sample is in the low 4 bits, the second sample in the high 4 bits). When the game records a Pokémon’s sound, it collects 8,000 8-bit samples of microphone input with a frequency of about 8,000 samples per second, and converts each fourth sample (starting with the first) into a 4-bit sample as follows:

-128 → 0; -127 to -112 → 1; -111 to -96 → 2; -95 to -80 → 3; -79 to -64 → 4; -63 to -48 → 5; -47 to -32 → 6; -31 to -16 → 7; -15 to 15 → 8; 16 to 31 → 9; 32 to 47 → 10; 48 to 63 → 11; 64 to 79 → 12; 80 to 95 → 13; 96 to 111 → 14; 112 to 127 → 15.

The game sets a variable, X, to the "exclusive or" combination of three bytes: the 100th, 500th, and 700th byte (counting from 0) of the recorded sound. If the user is a Chatot and hasn’t transformed, Chatter has a certain chance of confusing the target as follows:

• If X is less than 150, the confusion chance is 10%.
• If X is greater than or equal to 100 and less than 150, or if Chatot’s cry is the default one, the confusion chance is 0%.
• If X is greater than or equal to 150, the confusion chance is 10%.

The confusion effect is considered an additional effect by Serene Grace, the Pledges, Sheer Force, and Shield Dust.
