Encryption is a mask on data which may or may not contain more data itself.
Encrypted codes are formatted for use in the ActionReplay. They look like this:
All Evidence Max
G12C-TMX0-WRT5C
G2ND-C1RJ-G4TZ1
Decrypted codes are in raw format and can be edited. They look like this:
All Evidence Max
00690E90 000004FF
Codes for the GCN AR are encrypted for a number of reasons, just the top line of every encrypted code does three things meant to prevent user error:
The encryption of the codes also allows the ActionReplay to check for accuracy of what was entered beyond where it belongs. When a new code is entered into the AR it decrypts it, if it could not decrypt it then an "Invalid Code" error shows up.
Encrypting and Decrypting codes for the GameCube ActionReplay requires Parasyte's GCNCrypt program from the GCN Tools.
Note: Once a game's AR code is decrypted in GCNCrypt, if the Auto Identifier box is checked, it will set the Game ID and Region so any code can be changed or added then encrypted for the same game.
To decrypt an encrypted code, paste the encrypted code into the left text box in GCNCrypt then press the "Decrypt" button at the bottom. Output is on the right and can be copy/pasted onto the left for editing.
Many times after decrypting a code, the output won't be used. Hackers often decrypt codes from a game to automatically set the Region and Game ID for their new codes.
However, if a code was decrypted to be edited.. this is important:
Take the encrypted code, say this one:
All Evidence Max
G12C-TMX0-WRT5C
G2ND-C1RJ-G4TZ1
and then decrypt it in GCNCrypt, and this is the output:
All Evidence Max
01E22DC2 08000000
00690E90 000004FF
If the Auto Identifier box is checked (it should be) then copy the output over to the left and delete the top line of the code. This is done because- as said before- each time a code is encrypted, the top line gets added according to the Region and Game ID.
After that what's left is:
All Evidence Max
00690E90 000004FF
Now the code can be edited according to the AR code types below. After editing is done simply press "Encrypt" and copy the output on the right!
The single-line GameCube ActionReplay code types are the first two hex digits of a decrypted code. GameCube's memory range is from 0x80000000 to 0x817FFFFF so if the code's address is greater or equal to 0x81000000 then the code type gets 0x01 added to it. For the addresses used in the code types below, "rrrrrr" signifies that address. These are of course, decrypted.
| Type | Description |
|---|---|

|
xxxxxx: Number of bytes to write, zero-based (000000 writes yy to 0x80rrrrrr, 000001 writes yy to 0x80rrrrrr and to rrrrrr+0x01) yy: Byte to write. xxxx: Number of halfwords to write, zero-based (0000 writes yyyy to 0x80rrrrrr, 0001 writes yy to 0x80rrrrrr and to 0x80rrrrrr+0x02) yyyy: Halfword to write. yyyyyyyy: Word to write. |
|
xxxxxx: Byte offset from pointer. yy: Byte to write to address ((pointer at 80rrrrrr)+offset) xxxx: Halfword offset from pointer. yyyy: Halfword to write to address ((pointer at 80rrrrrr)+offset*2) yyyyyyyy: Word to write to pointed address (value at the pointer address of 80rrrrrr) |
