If you want to make Pad - Combos like L1 + L2 use our online Converter.

Finding Address of Joker Commands:
Method 1:
Need Labels without " " , e.g. Entrypoint.... if the game dont have it use our "Label Mates"
Search for (pad_dma_buf) and add 2.
Example: GTC Africa:



just add 2 and we have our Max Reserved Joker!
D02DB380 0000????
Note:
The same method can you use with this labels:
Pad_DMA_Buffer
g_Pad_Dma_Buffer
PADD1
Padinfo
Pad_rdata1

_____________________

Methode 2:
Search for Label ("libpad: buffer addr is not 64 byte align. %08x\n" )
Beispiel: Half Life (DE) v1



ps2dis brings us to the Byte - Address of the Label



we mark this address with Space and press F3 (Invoke Analyzer)



From this Address we have to go a few lines above till we come to an Addres like this ( ::FNC_xxxxxxxxx ). In a ELF-File which have Labels e.g. Entrypoint or by using our Tool "Label Mates" this address is named (scepadportopen) sein.This Address we also mark with Space and press F3 again.



Now we are near on our Joker Command. From the Addrees which ps2dis brings us (JAL #xxxxxxxx), we have to look (under and above) for an addiu with the Register a2.
We see that this Address links us to a nop which is our Joker Command (sometimes it dont links to another Address so try the Addiu as the Joker Address).
If we are on the nop which is our Joker - Address just add 2.
Joker Command Halflife
D03a5402 0000????

To get the Joker Address for Controller 2 just add 100.
Joker Command Halflife Controller 2
D03a5502 0000????

Multiple Line Joker Command
Sometimes you have to aktivate more than one line to get the right effect, so we need a special type of Joker Command.
Structure:
E0 xx ???? yyyyyyyy
x = how many lines you want to aktivate
???? = Pad
yyyyyyyy = Address of Joker Command

Example:
Joker Address (Add + 2):
00636782

Health:
201fd648 2402FFFF
201fd64c 2402FFFF
201fd650 2402FFFF

We want to refill our health by pressing R3
R3 = FFFB
The Healt Code has 3 Lines so we Take E00"3"

Press R3 to refill Health:
E003FFFB 00636782
201fd648 2402FFFF
201fd64c 2402FFFF
201fd650 2402FFFF
