Anti wave

[Acclamators]

hello. I once had a program on my psp back in the day that flashed some stuff to my psp and got rid of the xmb waves. Usually this would be a bad thing, but I did notice a speed increase in my psp. Would anyone know where to find a homebrew file like this and not a plugin? Also I was wondering if once the xmb waves were gone if CXMB would generate waves once activated because it runs off the memory stick and not the flash? Thanks any help would be tremendously appreciated.
