Hacking DS Lite repair videos

[gameworm2.0]

I've been looking around and found the gbatemp guide to disassembly/reassembly and thought I could also use a video so I have visual steps along with the guide so I have the best shot at fixing this. I've heard this repair takes a couple of hours, is that right?

depends on what u need to repair and u want to take ur time to take it apart carefully or else u might end up breaking something else
