    Welcome to the Shenmue Patch Code Guide, a full listing of unencrypted and
  encrypted codes for the greatest video game series ever: Shenmue! I've worked
  long and hard to uncover some elusive codes to make your gaming experience
  better. Whether you just want to "trade" in some of those slot machine prizes
  for Passport figures, or you want to completely open up the game, this guide
  will surely be of use to you. To use these codes, you'll need a game
  enhancing device such as GameShark or Code Breaker, DCcrypt, and a basic
  understanding of hex base. If you don't have the latter, don't worry. There
  is a section outlining hex base that will get you going in no time. Enjoy!

  Note: DCcrypt can be found at www.angelfire.com/planet/ssj2dark/DCcrypt.zip

    Game enhancing codes generally use hexadecimal (hex) base for all numbers,
  including addresses and values. To use codes effectively, you should
  understand hex. The decimal system is base ten; once a digit is increased
  ten times, the next digit increases by one. The hexadecimal system is base
  sixteen; once a digit is increased sixteen times, the next digit increases by
  one. The extra six "numbers" in hex are the letters A-F. This is a
  progression table comparing sixteen decimal and hexadecimal values:

  Decimal | Hexadecimal
  ---------------------
  1       | 1
  2       | 2
  3       | 3
  4       | 4
  5       | 5
  6       | 6
  7       | 7
  8       | 8
  9       | 9
  10      | A
  11      | B
  12      | C
  13      | D
  14      | E
  15      | F
  16      | 10

    The most convenient method to convert decimal to hex is by using the basic
  Calculator program on your computer. Enable the Scientific option, then type
  in your decimal value, and enable hex mode. Your decimal number will be
  converted to a hexadecimal value. There are also freeware programs such as
  Hexit available, if you prefer.

The Basics of Codes (T5)                                                        
-------------------------------------------------------------------------------

    Before you begin executing lines of code with your game enhancer of choice,
  it's a good idea to understand how those sequences of numbers and letters
  make things happen in your game. Similar to a computer, the memory for a
  video game is comprised of thousands of addresses, each holding a particular
  two bit value, which I often call 'xx'. The range of xx is from 0 to FF, or
  in decimal, 0 to 255. Game enhancing codes overwrite these values by
  specifying a certain address and a value to be written to that address. A
  template for these types of codes (while unencrypted) looks like this:

    ttaaaaaa zzyyxxww (Address Format)

    Where tt denotes the code type, aaaaaa is the starting address the code
  will modify, and zzyyxxww contains the quantities to be written (in hex
  base). An address line (ttaaaaaa) must be immediately followed by a quantity
  line (zzyyxxww), unless it is an advanced type (04 or higher). For our
  purposes, basic code types will suffice. These code types used are type 00,
  01, and 02. Following is a table comparing code types and abilities:

  Type |     Example     | Effect
  ------------------------------------------------------------------
  00   |00aaaaaa 000000xx| Assigns xx to aaaaaa
  ------------------------------------------------------------------
  01   |01aaaaaa 0000yyxx| Assigns xx to aaaaaa and yy to aaaaa(a+1)
  ------------------------------------------------------------------
  02   |02aaaaaa zzyyxxww| Assigns ww to aaaaaa
       |                 |         xx to aaaaa(a+1)
       |                 |         yy to aaaaa(a+2)
       |                 |         zz to aaaaa(a+3)

    At first, type 01 and 02 codes can be difficult to understand. In these
  codes, the quantity line possesses two or four values (xx and yy for 01 or
  ww, xx, yy, and zz for 02). Each of these values is written to a different
  address. The first value (xx for 01 or ww for 02) is written to the address
  aaaaaa. The second value (yy for 01 or xx for 02) is written to the address
  aaaaa(a+1), the address right after the address in the code. The third and
  fourth values for type 02 work similarly, affecting subsequent addresses. An
  important rule to remember is that the quantities for type 01 and 02 codes
  follow right to left, in that values on the right affect the first addresses,
  and values on the left affect the latter addresses.

    One aspect of codes that can be confusing is code encryption and
  decryption. For one reason or another, many game enhancers choose to encrypt
  their code lines, meaning that the lines themselves are meaningless, and give
  little insight as to what they do. The process of encryption basically
  reassigns values based on the sequence and identity of the original
  characters in the code. A useful rule is that unencrypted codes always begin
  with a 0, while encrypted codes do not. For the Sega Dreamcast, there are two 
  main choices for game enhancers: the GameShark, and the Code Breaker. The 
  GameShark requires encrypted codes, and their encryption method is quite
  complicated. You won't be encrypting codes in your head by adding 1 to every
  value. Fortunately for us, a tool has been created called DCcrypt. This nifty 
  utility allows us to encrypt and decrypt codes for the GameShark CDX, giving
  the average gamer access into the code realm. Operation of DCcrypt is as
  simple as type and click, with no settings to worry about. However, if you
  own a Code Breaker or other rare game enhancing device, you don't need to
  encrypt your codes. Since the GameShark/Action Replay is the most common game
  enhancer, I have written this guide assuming that you are using one. If
  you're lucky enough to have a Code Breaker or Xploder, skip the steps
  concerning encryption.

    Keep in mind the laws of game hacking: use codes carefully, in small
  groups, and check carefully before saving. In rare cases, an improperly
  entered code can have disastrous effects, but the threat is minimized if you
  only save when certain that the desired effect is the only change in the
  game. Only enable a few codes at a time to prevent interference and a halted
  load. Also, when deciding quantities and customizing codes, always try to
  hack within the limits of the game. Giving Ryo 255 Phoenix Mirrors may seem
  harmless, but you may run into a problem later in the game. Your goal should
  be to create the illusion that your game was never hacked at all. 

    Finally, it is good to note that in Shenmue, subsequent addresses contain
  information for similar items. For example, the addresses for all the Sonic
  collectables are right next to each other, and the addresses for all the move
  scrolls increase by two for each scroll. These patterns can be useful when
  you know the address of one item, but want to modify a similar item. Say you
  have the starting address for Hand moves (aaaaaa), but want to modify Elbow
  Assault, the fourth hand move. Knowing that addresses for moves increase by
  two for each move, you can deduce that the address for Elbow Assault is
  aaaaa(a + 2*(4-1) = a + 6), that is, six addresses after the starting
  address. This is the basic concept for custom code creation; advancing from
  a known address until the address for the item of interest is found.

  Note: a value of 64 corresponds to complete mastery. Also, giving a value to
  a move not yet on the move scroll can be done, but the move will not be
  available until it is learned in the game.

Custom Code Tutorial (T12)                                                    
-------------------------------------------------------------------------------

    Many of the codes listed here are code type 02, meaning that they modify
  four address values. In certain cases, you may only want to modify only one
  or two address values. The best solution for this situation is a custom code;
  one that is created entirely by you. A code is comprised of three parts: a
  code type, starting address, and quantity line. When you create a custom
  code, you must determine each of these parts. This section is devoted to
  helping you finalize each section of code, and putting it all together to
  form the complete custom code.

* Code Type
    The code type will determine how many address values are modified. So, you
  need to know how many address values need to be changed. The following list
  notes the recommended number of address value changes for particular items:

  Menu/Collectable Items: 1
  Cassettes/Moves: 2

    Now, recall that the 00 code type modifies one address value, and the 01
  code type modifies two address values. Now you have your code type. Later on,
  you'll need a number called n, which is equal to the number of address values
  changed by your code (found in the list above). Note whether n = 1 or 2, and
  keep that in mind for the next step. 

* Starting Address
    Determining the starting address is the most difficult procedure in
  creating custom codes. First, your item of interest has a value associated
  with it. The following list outlines the guidelines for these values:

  Menu Items: its order in a value list
  Collectable Items: its order in the Complete Collection value list
  Cassettes: the cassette slot to be modified
  Moves: its order in the Hand, Leg, or Throw value list

    Record the item's value (v) and the name of the value list it appears in
  (or Cassette Collection for cassettes). Next, scroll up to the code list with
  the same name as the value list. Look at the Address Format section, and
  record the first address in the list (remember that Address Format is
  ttaaaaaa, where aaaaaa is the address). This address will be called s. Now,
  you need to solve for t, the value to be added to s. Use this formula to
  solve for t:

    t = (v - 1) * n

    Convert t to hex base (0h[t]), and add it to s just as you would two
  values. The final result is your custom code's starting address!

* Quantity Line
    Finally, you need to write a quantity line to accompany your address line.
  The following list will help you create the proper quantity line:

  Menu/Collectable Items: 000000xx (xx = quantity of item)
  Cassettes: 0000aaxx (aa = identity of cassette, xx = quantity of cassette)
  Moves: 000000xx (xx = proficiency of move, 64 is complete mastery)

    Once you have written your quantity line, you have all three sections for
  your custom code! Simply place them together following the code model:
  ttaaaaaa xxxxxxxx. If you are using a GameShark, there is one final step
  before your custom code is usable.

* Encryption (GameShark Only)
    In order for your custom code to work on a GameShark, you must now encrypt
  the code. Open DCcrypt, and paste the address line into the text box. Click
  Encrypt, and place the result above your quantity line. This is your
  encrypted custom code, ready to use with your GameShark!

* Examples
    In order to help you through your first custom codes, I've written two
  common examples of custom codes, and the steps required for the final result. 

* Super Sonic Example (Set 1 Super Sonic figure to collection)

  * Step 1: Code Type
    Code Type: 00
    n = 1

  * Step 2: Starting Address
    v = 51 (Found in Complete Collection Value list)
    Value List Name: Complete Collection
    s = 221CBC (first Address Format code line in Complete Collection list is
                02221CBC, remove first two characters to get starting address)
    t = (v - 1) * n = (51 - 1) * 1 = 50
    0h[t] = 32 (50 in decimal = 32 in hex)
    Starting Address = s + 0h[t] = 221CBC + 32 = 221CEE

  * Step 3: Quantity Line
    Quantity Line Model: 000000xx
    xx = 01 (One figure desired)
    Quantity Line: 00000001

  * Unencrypted Code: 00221CEE 00000001

  * Encrypted Code: 173C5819 00000001

* Hip De Hop Example (Set 3 Hip De Hop cassettes to the tenth cassette slot)

  * Step 1: Code Type
    Code Type: 01
    n = 2

  * Step 2: Starting Address
    v = 10 (tenth cassette slot)
    Value List Name: Cassette Collection
    s = 221DBC (first Address Format code line in Cassette Collection list is
                02221DBC, remove first two characters to get starting address)
    t = (v - 1) * n = (10 - 1) * 2 = 18
    0h[t] = 12 (18 in decimal = 12 in hex)
    Starting Address = s + 0h[t] = 221DBC + 12 = 221DCE

  * Step 3: Quantity Line
    Quantity Line Model: 0000aaxx
    aa = 02 (Found in Cassette Values list)
    xx = 03 (Three cassettes desired)
    Quantity Line: 00000203

  * Unencrypted Code: 01221DCE 00000203

  * Encrypted Code: 13BC1819 00000203

Future Updates (U13)                                                            
-------------------------------------------------------------------------------

  Look for these additions in the future!

* Addresses to enable moves not yet learned.
* Addresses to unlock Passport features.
* Addresses to unlock Notebook entries.
