Telling you that you can copy your games isn't condoning modifications to the console. This is where we get into the area of kids playing lawyers again.
No no, I was just kinda pointing out its funny cause they dissaprove of you messing around with the consols internal parts, yet they know that if you are going to make backup cds, and they say you can do this, then your going to have to. Though I relise just now that thats not entirely true, as I managed to play pirated, eer "backup" cds on my PS without chipping it, so really Ive just disproved my whole idea. Damn. =)
Aside from copyright issues, there's a very good reason not to allow the warranty after you've altered the machine in any way. A warranty from Sony is a guarantee that they put together the machine right, that everything's in good working order when you receive your machine. If this isn't true... i.e., the machine doesn't work, or breaks down in an unreasonable amount of time... because they guaranteed their work, they will replace or repair it.
Once you've opened up the PS's casing and fiddled around with the components, who's to say what condition you received it in? In order to protect themselves from false claims and the stupidity of others, most every company on the face of the earth refuses to warranty anything that's been messed with.

I'm not even going to go into the definition of what a ROM is (technically, those NES games you download aren't ROMs... they're writable copies of ROMs. A PS game, on the other hand, is unwritable, so is a ROM... a CD-ROM, in fact. Ha, I lied. I did go into it.)
