Misc Questions regarding the PS2 inside of the PS3 launch models

[Kazmar]

Hallo.
I was thinking really hard about the launch model PS3 just now, and it occurred to me that I've always heard the PS2 BC described as "A PS2 shoved inside the PS3". Now, the PS3 is huge, and maybe huge enough to fit both a PS2 Slim (wow those are tiny) and a whole PS3 inside, but I assume Sony still did some amount of miniaturization. Is it like the PS2 on an SOC? And, say if it were, couldn't that be used to make a portable? I know it'd be a sin to sacrifice a launch PS3 for a PS2 portable, but what if?
I'm just kinda throwing stuff out there right now. Basically, if the backwards compatibility of a system relies on an SOC (which my understanding is just one chip), wouldn't that make portibalization of one chip relatively easy compared to miniaturization of multiple chips?

Anyway. Maybe I'm just crazy (lol) but throw your thoughts in, though I'm probably totally off base.

I am not an expert on the subject, but afaik, they combined the PS2's Emotion Engine and Graphics Synthesizer and put the chip onto the board. Here's a pic of the launch model MOBO if you're interested.

Yeah that was kinda my understanding!! So if the entire PS2 like brainhole kinda deal is inside that one chip, couldn't that in of itself be great for portabalization of a PS2 using the PS3 BC SOC? I know you said your not an expert though, but this sorta supports my theory.

From my understanding of using a BC PS3, I don't believe there's any system menu built into the chip. Because of that, there would be no way to hack it to allow it to load games off a USB or some other means (usually using OPL). It depends on the PS3-side of the house to recognize the game and tell the PS2 EE+GS to play the content.

Most PS2 slims and all superslims (at least by model numbers, and including the 100% stock miniaturization champion 79xxx) already use the EE+GS (which BTW was invented for the PSX, then the 70xxx alternated between separate and combined depending on stock, then.....)

if the backwards compatibility of a system relies on an SOC

Well, once you have an EE+GS you would still need memory (the two "mickey mouse ears" chips above it in Drewby's photo), a coprocessor, a mechacon, a video DAC, glue logic, external interfaces, and probably-I've-missed-something to make a PS2 out of it!

And yes, even the CECH-A and B emulate the "minor" chips...

Is there supposed to be more than the initial steps? Nothing loads for me after the firs 3 pictures.

I see it now. The next button doesn't load and only shows the 'missing image' icon, so I assumed it was broken. Thanks!

It's bastardizing PS2 games, just like the PS2 did with PS1 games.
