AoB (Array of Bytes) modifies data values in flash games, essentially rigging the game itself in your favor by changing aspects of game play (eg. invincibility, unlimited ammo/time). You still play the games manually, as opposed to score-sending (where the game is untouched and autoplayed). If you used a Gameshark on your N64/PS/XBox when you were younger, AoB = Gameshark
Freeze rate is low unless you modify values to attain some impossible score.
