Except this guy doesn't know what he's talking about.

Yes there is a Playstation emulator and yes it can emulate basically ALL Playstation games. Only problem is most games aren't playable at .5 fps.

Common sense would figure out if they can't emulate a PS1 they can't do a PS2 as claimed.

They can't do the N64 either and I don't think they have GBA working that well yet either, but most of the others they can do at decent speeds with frameskipping.

Well, 2.0 can do most of the homebrew that people use. (Mainly some simple applications and emulators) and the only thing you can't really do is UMD emulation which if you really wanted to, you could just downgrade to 1.5.

It wouldn't really fix any problems other than storage, but to answer your question, yes there are products like that which are built for PSP, I-Pod and similar products.

Yes, there is a GBA emulator and it seems to run a lot better than I had thought.

I think frameskip works exactly how it sounds.

Frameskip 0 - Frame 1, Frame 2, Frame 3, Frame 4...
Frameskip 1 - Frame 1, Frame 3, Frame 5, Frame 7...
Frameskip 2 - Frame 1 - Frame 4, Frame 7, Frame 10

And so on.

I'm fairly sure the new SNES emulator uses the GFX core on the PSP, not totally sure though.

There is no Dreamcast emulator to my knowledge.

And it's not as easy as you would think to emulate a system. You have to basically recode the entire system and make it use different pieces of hardware. They haven't fully figured out how to use the PSP's hardware yet either.

Look at the computer though, they still don't have a good PS2 emulator out.

Raising fish eh?

Play some Harvest Moon games. (SNES, PSX, PS2, NGC)

Simulated farm, I'm not much of a nature person, yet I love this game. You get to build your own farm, plant crops, raise cattle, a horse, a dog, some sheep and even woo the girls in the town. Really an amazing game.

Well, the best DS emu for the PC runs the games quite glitchy or just not at all, so I doubt there would be any development for a while.

Also, like you said, there are the obvious complications such as the dual touch screens.
