Where can I download ps2 game saves and how for the PS3?

[NEO GEO DRAGON]

I want to download some PS2 game saves onto an USB memory stick on my PC and transfer it to the PS3. Where can I download the saves and what folders do I need to create on the USB stick so that the PS3 will recognise the files.

I'm not after action replay saves. Just straight PS2 game saves. Thanks in advance.
