Batman Arkham Asylum Grapple/Glide fix?

I'm sure those who find this post are using pirated PC copies of Batman Arkham Asylum. It's weird to see people's asking such question while thinking it's a bugs of the pc games, no it's not! This is an anti-piracy counter measures implemented by Eidos to break your game at some point. So you can get a taste of the game and buy the original copy of Batman Arkham Asylum. Its a win-win situation. In fact, it's one of the most clever DRM I've seen which a crack doesn't seem to fix the problem after several months. There's some patch/crack released claim to fix the gliding and randomly missing grappling point problems, but none seems to fix it completely. Is there a fully playable pirated copies of Batman Arkham Asylum on the internet, no one knows. But some pirated gamers do says they completed the game with fixes available on the net, some claim it doesn't help at all. In the end, if you think its a good game, buy it!
