In Modern Systems

without mods the closest thing I know is hd loader or hd advance.
But I don't think those will do the emulation thing.

I know next to nothing about emulation on modern consoles, but remember seeing this site on another forum if it helps:

Good point Luke. I forgot all about savestates and how the Xbox has a HD and the PS2 has one only through add-on until I read something in another thread about someone saving states on a memory card.
