Explanation

Here you will find an incomplete list of descriptions of memory addresses/locations/structures in Okami, discovered via Reverse Engineering.

Address refers to the path to the location in memory of the given data. These will be of the form dllFile.dll+offset or dllFile.dll+offset + pointerOffset + pointerOffset or similar. Offsets will be given in hexadecimal. Some addresses may have a link to a separate page which explains in greater depth its meaning and behavior.

Short Description refers to a brief phrase or sentence which describes the meaning/purpose of the value.

Type refers to the way the value located at the given address is interpreted. The common types are:

  • Float: A floating point value, representing a fraction/decimal value. Generally used for values which vary continuously. Can take on a very wide range of values, with varying degrees of precision. A float is always 4 bytes in length.
  • (1/2/4/8) Byte(s): An integer value. Sometimes signed (positive or negative) sometimes unsigned (not negative). Can represent countable quantities (e.g. number of a given item in the inventory), addresses of other values, or a wide variety of other things. Sometimes represented in hexadecimal or decimal. Each byte represents 8 adjacent bits (binary on/off values).
  • Array of Bytes: A list of byte values of arbitrary length. Can contain many independently meaningful addresses. Usually listed here to represent a group of related values stored adjacently in memory.
  • String: A list of characters of arbitrary length, usually representing a something like a word, sentence, or filename.
  • Binary: A set of values which are either on/off or true/false. Often used to represent flags, such as whether a certain one-time-only action has been performed. Because addresses can only refer to bytes, and not individual bits, each binary address listed here will represent a group of 8 actual bits/flags. In many cases, not all of the bits in a byte are used (the unused bits always remain at 0). For these values, the description will describe the overall contents of the byte, and the detailed values will be present in the Bitfield Table, linked in the Article column

Range describes, roughly, the range of values stored at the given address. This doesn't generally indicate precise bounds.

Units describes the type of quantity represented by the value. For values which don't represent some kind of quantity, this column may be blank.
