For my HeartGold JAP version, the anti-piracy freeze gets worse little by little...first it freezes after 9 minutes of gameplay, then 2 minutes, then it started freezing after a few seconds today, that's why I got the patch...to be honest, I didn't really want to get it since I already made it very far into the storyline, but the patch seems to be working fine, and most important parts are in English, so its pretty cool.
