What can it do?

First off, hi all o/

So, I got kinda lucky with my PS3.

Long story short, a dude I work with came in one day complaining his sons PS3 was scratching disc's. He knows I "tinker" with 360's and I also build/repair PC's as a side line.

I told him I'd take a look at it if he liked and we left it at that. Next day I went round to the bonfire (it was'nt lit) to throw some rubbish on. And there was a PS3 sitting right there!

I popped it in the van, and went round to see my mate, and he said his wife had poured a can of coke through the vent holes in an attempt to go for an insurance job, which he talked her out of, and they went out and simply bought him a new PS3.

So I asked him if I could have it, he laughed, said its ****ed now, and of course I could have it.

Took it apart, mopped up some still wet coke and left it to dry. Then I turned it on and it worked, wouldnt take a disc as the mech was sticky with the now dry coke. I took the drive apart and washed the plastic parts in warm soapy water, put it back together and it now takes blu-ray discs but it freezes shortly after playing it.

So it became my new media center using PS3MS. For this job it works flawless - playing back 1080p media flawlessly. So the system it's self is just fine.

I could of course replace the drive with a unit from flea bay, but Im not sure I want to, just yet atleast. Through fear it will give up the ghost due to the coke abuse!

So, after all that, what else can I do with it? Is there anyway I can get games to run off the HDD? Or anything else that will make the sexy black box play games without a drive?

EDIT: I downloaded Darkvoid demo off PSN and the screen goes black when I try play it. So I guess its not as healthy as I thought. I doubt its overheating either as the game doesnt even start.

Is this a known thing that maybe Im doing wrong?
