Hacking How do I get certain Ps2 games to work on PS3?

[SG854]

Hi, I'm trying to get Star Wars Battlefront 2 to work on the ps3 and this wiki page here says I need a config file.
So how do I make one? And what do I have to do to get it to work? It stutters and freezes without one.
I'll also need to know how to make one for other Ps2 games.
Thanks to anyone that can help.
