How to Locate Joker Commands
Load the game disc onto your computer in the DVD drive.
Open and view the folders on the disc through the location through the My Computer folder.
Search the disc for a file labeled ̶0;scus/slus.̶1; There will also be a string of numbers in the filename (such as ̶0;SCUS_971.34̶1;). Save this file to your desktop.
Run PS2DIS. Open the scus file saved on your desktop with PS2DIS.
Run PS2DIS Analyzer. You can do this by selecting the Analyzer line in the PS2DIS menu options and selecting ̶0;Invoke Analyzer.̶1; This will parse the code on the disc into a manageable profile for you to sort through. This step may take a little while, and might seem to freeze, but eventually it will finish analyzing and you will be able to continue.
Locate the label containing the Joke command line. Once the Analyzer has completed its work, you will be able to scan through a list of labels on the disc. There are numerous labels containing fields where the Joker command can be placed. Some common examples of these labels include: ̶0;pad_dma_buf,̶1; ̶0;pad_dma_buf2,̶1; ̶0;Pad_DMA_Buffer,̶1; ̶0;g_pad_Dma_Buffer,̶1; ̶0;PADD1,̶1; ̶0;Padinfo̶1; and ̶0;Pad_rdata1.̶1;
Double-click on the label pertaining to the types listed in the above step. This is where you will find the Joker command code. You may have to search several different labels before coming across what you want, but searching begins here.
Locate the Joker command line. The structure of a Joker Command begins with the letter D, followed by a string of seven characters, followed by a space and a four-character string representing a corresponding button on the PS2 controller. Once you find a line of code that meets this look, you have found your Joker Command.
