Download the .pnach file and put it in your "cheats" folder.
Now here's the hard part. Notice the instructions on how to change the offset. It says:
"patchExtended=1,EE,489674,short,0000,0008 // Adjust the 2nd to last value to change audio offset (signed value, range from -32768 (0x8000) to 32767 (0x7fff)). CHANGE THE 0000, NOT THE 0008!"
You need to change the "0000" to a certain hexadecimal value. Unfortunately, I can't describe this properly since hexadecimals aren't my forte. This website might help a little.

My laptop is offsync with any DDR Emulator. My .pnach file has the "0000" value as "ffed"
