PlayStation Action Replay 3, GameShark 3 and GameBuster 3

The code types listed here are documented to work for Action Replay (English, Japanese, French), GameShark and Game Buster version 3 cartridges. They are also supposed to work for some slightly earlier versions, namely GameSharks 2.41 and above, UK Action Replay, German GameBuster and French Action Replay 2.8 and above, and Japanese Action Replay 2.5 and above.

80 -- Store Word

Repeatedly writes the given 16 bit value to the given memory location.

30 -- Store Byte

Like 80 code but affects only the byte at the given address, which address may be odd or even.

50 -- Serial Code

5000RR0S IIII

RR is the number of repeats

S is the size. multiple of 2 for words, 1 for bytes

IIII is options increment for written value

Use with 80/30 codes to avoid lots of repetitions of similar codes if you wish to update a lot of consecutive memory locations.

The 50 code itself must precede a normal store code. The size of the address increment must match the type of the store code, since it specifies a value by which to increase the target address on each repeat. That is, with 80000000 codes this S value must be even (2,4,6,8,A,C), but with 30000000 codes (which work on bytes) this S value can be any number from 1 to F.

Example.

   50000302 0000
   801CCFBC 1111

is equivalent to

   801CCFBC 1111
   801CCFBE 1111
   801CCFC0 1111

And

   50000302 0001
   801CCFBC 0001

is equivalent to

   801CCFBC 0001
   801CCFBE 0002
   801CCFC0 0003

Conditional Codes

D0 -- If Equal

If word (16-bit) value in the supplied location is the same as the supplied value do the next code, otherwise skip it.

D1 -- If Not Equal

If the word value in the supplied location is different from the supplied value do the next code, otherwise skip it.

D2 -- If Less Than

If the word value in the supplied location is less than the supplied value do the next code, otherwise skip it.

D3 -- If Greater Than

If the word value in the supplied location is greater than the supplied value do the next code, otherwise skip it.

E0 -- If Byte Equal

If byte value (8-bit) in the supplied location is the same as the supplied value do the next code, otherwise skip it.

E1 -- If Byte Not Equal

If byte value in the supplied location is different from the supplied value do the next code, otherwise skip it.

E2 -- If Byte Less Than

If byte value in the supplied location is less than the supplied value do the next code, otherwise skip it.

E3 -- If Byte Greater Than

If byte value in the supplied location is greater than the supplied value do the next code, otherwise skip it.

Increment (add to) and Decrement (subtract from) Codes

10 -- Add

Adds the value supplied to the word (16-bit) value at the location. Note this is done repeatedly, and so it, and all the other increment/decrement codes, are difficult to make useful.

11 -- Subtract

Subtracts value supplied from the 16-bit value at the location.

20 -- Add Byte

Adds the value supplied to the 8-bit value at the location.

21 -- Subtract Byte

Subtracts the value supplied from the 8-bit value at the location.

New Code Types

Several additional conditional codes were made available in all versions 3.x. They are also available in newer version 2 software (US 2.41+, UK 2.8+, JAP 2.5+).

Must Be On / Master Codes

Not a code, but a feature. If a code name starts with the text "(M)" or "(m)" then that code is always on.

D4 -- Do Code If Joypad

If joypad press equals word value do the next code.

Table of JoyPad values

0001 L2

0002 R2

0004 L1

0008 R1

0010 Triangle

0020 O

0040 X

0080 Square

0100 Select

0800 Start

1000 Up

2000 Right

4000 Down

8000 Left

Add combinations. E.g. Select+L1+R1 = 0100+004+0008 = 010C

D5 -- Codes ON If Joypad

If joypad press equals word value, turn all codes on. This "turn codes on/off" feature is permanently available in all games and defaults to "SELECT+L1+R1" for on and "SELECT+L2+R2" for off. The D5 and D6 codes are available if you need to change the buttons used or disable them. If the value given is zero (D5000000 0000 or D6000000 0000) then joypad functions are disabled (This is the same as "joypad toggle disabled" in the options screen).

D6 -- Codes OFF If Joypad

If joypad press equals word value, all codes off. This does the opposite of the D5 code.

More Extended Codes

There are several other interesting extended codes which are available in more recent GameSharks.

C0 -- Enable All Codes If Equal

If word value in location supplied is the same as value, enable ALL codes, otherwise disable codes, and don't do any. A C0 code if the same as a D0 code except it acts on ALL codes. This is useful for games that don't load when codes are on, or if you want to avoid repeating the same D0 code a lot of times. (Beware in that latter case that you will disable ALL codes in all selected code sets with the single condition).

C1 -- Code Initial Delay

Delay codes being turned on for a period of time specified by the value part of this code. By default this value is set to 1388 hex (5000 decimal) which waits about 10 seconds before activating codes. This can be a useful alternative to a D code for keeping codes off while a game loads.

Example: To delay all codes from being turned on for about 30 seconds in most games use the code C1000000 4000. The value you use depends on the game you are playing--the value 4000 might be 30 seconds on one game, but may only be 10 seconds on another. The only way is to know for sure is to experiment. You can tell if codes are on or off when by going in to the "In Game Menu" and looking at the text "Codes are ON". If it says "Codes are ON" then codes are on, if it says "Codes are ON." (with a dot (".") at the end of the string) then codes are actually off until this timer runs out.

C2 -- Block Move

This code copies one or more bytes from one memory location to another. The code must be used in pairs of two codes. The first code--the actual C2 code--contains the source address, and its value part is the number of bytes to copy. The second code contains the destination address. Both the value part and the op-code part of the second code are not used.

Example: Copy 164 bytes from memory location 801CCFB8 to 801D502C.

     C21CCFB8 00A4
     101D502C 0000
