## `$00`−`$EF`: `anim_wait` *length*
-## `$D0`: `anim_obj` *object*, *x*, *y*, *param*
+## `$D0`: `anim_obj` *object*, *x1*, *x2*, *y1*, *y2*, *param*
+
+The *x1*/*x2* and *y1*/*y2* pairs specify the position on screen of the animation object.
+*x1*/*y1* specify a tile position, and *x2*/*y2* specify a pixel offset from that tile.
+
+Values for *x2*/*y2* are in the 0-7 range, since 8 pixels make a tile.
+
+Values for *x1* are between -16 to 31. In practice *x1* starts between 0 to 15, then between -16 to -10. Negative values are relative to the opponent, while positive values are relative to the player. Useful values are between 14 to -10 (for the opponent) and between 0 to 13 (for the player).
+
+Some sample values are:
+
+- 0: player left border
+- 6: player center
+- -15: enemy center
+- -10: enemy right border
+
+Values for *y1* are also between -16 to 31; the useful range is between 2 to 14.
+Values between 2 to 8 will be in the opponent's area (2 being the top border and 8 being the
+bottom border), and values between 8 to 14 will be in the player's area (again, 8 being the top border and 14 being the bottom border).
+The center of the body is often 2 to 4 tiles away from the border (i.e., 5-6 for the opponent or 10-11 for the player).
