PS2 games can use any one of four different value systems for storing button presses depending on the game. The only way to determine which system is used is to hack the joypad reader itself.
These are the values used in the GS D4, D5, and D6 code types. Combine buttons by using bitwise OR.
Button | Value |
---|---|
Select | 0x0001 |
L3 | 0x0002 |
R3 | 0x0004 |
Start | 0x0008 |
Up | 0x0010 |
Right | 0x0020 |
Down | 0x0040 |
Left | 0x0080 |
L2 | 0x0100 |
R2 | 0x0200 |
L1 | 0x0400 |
R1 | 0x0800 |
Triangle | 0x1000 |
Circle | 0x2000 |
X | 0x4000 |
O | 0x8000 |
This alternative button storage method had its values combined using bitwise OR. These values are determined by byteswapping the normal values.
Button | Value |
---|---|
L2 | 0x0001 |
R2 | 0x0002 |
L1 | 0x0004 |
R1 | 0x0008 |
Triangle | 0x0010 |
Circle | 0x0020 |
X | 0x0040 |
Square | 0x0080 |
Select | 0x0100 |
L3 | 0x0200 |
R3 | 0x0400 |
Start | 0x0800 |
Up | 0x1000 |
Right | 0x2000 |
Down | 0x4000 |
Left | 0x8000 |
These values are determined by subtracting the Normal joypad values from 0xFFFF. Buttons are combined with bitwise AND.
