Busted bluray drive - why hasnt someone developed a working bluray drive bypass yet?

I realize that i may get the palm to the head gesture in response here but its something i dont understand. With all the developments in the ps3 arena, why hasnt someone created a true blu-ray drive bypass. Why do some games work with a disc and some without? Maybe i'm the only one with the problem, but it would be awesome if there was something that could be done. So enlighten me or call me a retard, i dont care but if i can get an explaination, i'll be happy :)

Yeah, I must have tried a dozen different ways to get LBP working without a laser for my son. Gave up long time ago.
Also gave up trying to restore blu ray playback on another one.
It's been a **** all year for PS3 hacking.

you know theres a hardware hack that allows you to swap bluray drives lol you will get bluray playback games etc ive done it myself actually have a thread about it! and you can swap drives with different lasers as long as its a phatboy to phatboy or slim to slim
