I'm having a problem finding a filter for my PSP, I've been trying to find VM Natural filter, especially the Sparkle one for a long time and so far, every single one I've downloaded does not seem to load or work. Does anyone know some other websites to download it or what is wrong?

Thanks!

I just downloaded a whole VM package and didn't work, is that filter only limited to PSP8? (because I have PSP7)
