I know next to nothing about them. Can anyone give me some info, like what they are and what exactly they do? Can I stream using them through a capture card? Do I need to have a beastly PC to use it? What emulator works best? Are they safe to download? 'Cause this whole no backwards compatibility on the newer PS3s just ain't gonna fly. I'd love to stream some of my older PS2 games. Thanks in advance.
