all PS3's even the slim can play ps1 game's

I also play ps1 games sometime's and i can indeed and have played some of my PS1 classic game's on my both fat and slim ps3's

Wait, can I actually go right now and insert a PS1 disc into my sister's PS3 and play it!? Please tell me before my feet begin dancing of joy.
But wait, if so then PS1 games are region coded right :( Damn, I wanna play Valkyrie Profile T_T

Edit:

It's an 80GB PS3

I don't mean to call you out, but Sony is known for firmware updates that cause a lot of problems.  It just isn't normal for the FW update to brick the console.

The firmware bricking isn't wide spread, but just imagine if you were one of these poor bastards that had the misfortune.  Would you not be very upset?  Or would you say ahh shucks, no biggie and then go buy another system?  I know I would be ready to go smash something.

well, I have the original 60gig PS3, so I'm good...though I am starting to run out of space.....

Sony is known for Firmware updates that cause a lot of problems?  Since when?  Has there ever been actual proof that an update caused problems?  Or, far more likely, did a handful of people have problems that would have happened anyway that just so happened to occur right after they did a firmware update? 

If Microsoft had more firmware updates, I guarantee we would have heard about this all the time...that their firmware updates caused RROD, just because RROD happened so frequently and the law of averages.

Yes.  I've played the old PS1 Final Fantasy games on my PS3.  It works on all PS3's.

You can't trust Sony.

They're a large corporation.

You can't trust large corporations.

They're so big and so profit driven that they'll break any promise they've made if it will help the bottom line by 1%.  Then make it sound in PR like you imagined them making said promise.

Me.  I have no problem with there consoles... but I bought a BC PS3 used.

Now their electronics... ick.

I am certain that microsoft has problems with their firmware as well.

But your right, the PS3 has never had an instance of fw upgrade problems before. My bad.

yes..for example:

I have played the ps1 eternal eye's, chrono trigger and cross, ff:7,8 and 9 on both the fat and slim, so there's your answer

In other words there truly never has been proof of it, but you'll use sarcasm because the only "truth" to it is that some people on internet forums complained about it.  And everything on the internet is 100% true.
