I don't know if this will work but you can try
1.Download and install Cheat Engine
https://www.cheatengine.org/downloads.php
2.Run the game and you can close the game window(don't close pcsx2)
3.Run Cheat Engine and select pcsx2
4.On the right side tick the "Hex" checkbox set Scan Type to Exact,Value Type to 4 Bytes
In Memory Scan Options set start to 20000000 and end to 21FFFFFF
5.In the Value type 64420008 and search(it will probably not work if you get more than one address)
7.Select that address and click on the read arrow 3 times
8.Double click on the second address(in the address column)and after the address add -1AEC4 and hit ok(it will change the address)
9.Double click on the 3rd address and add +335F7C and hit ok
Now double click on each address copy and replace the text below with the address
patch=1,EE,first address,extended,00000000
patch=1,EE,second address,extended,AE000060
patch=1,EE,third addresss,extended,00000000
Make a pnach file out of what you find and try it
You can also change the values in Cheat Engine to see if it works before making a pnach(pcsx2=>System=>Resume to see if they work)
