Why do you want to import this peculiar Korean console instead of a Sony and Nintendo product? Because it's a completely different animal. It pretty much marries PC cross-console emulation and l33t hax0r media goodness into a portable form factor. Sounds like the Gizmondo right? Yes! Except without the car crashing and financial rape - this thing is actually real and thriving.
You can even manipulate and evolve with your own filthy Linux-coding hands, or through binary downloads across a plethora of obscure forums. They are in their third generation right now - the most notable is a 2D system called
the GP2X which plays arcade systems via MAME, Game Boy, Game Boy Color, Game Gear, Neo-Geo + CD, NES, TurboDuo, Master System, Genesis, SNES, + homebrew games... as well as common PC formats such as DivX, XviD, MP3, OGG, NSF, JPG, and so on.

A 3D capable system similar to the PSP is
the XGP, which they were redesigning soon. I typically enjoy retro games on a portable console over the newer in depth ones because my portable play sessions are very short, so this is perfect for me. Plus, it's l33t. If you're interested,
here's a shop that carries them and yet
another one with more merchandise.... and here's one place that has
good starter downloads. The redesigned version pictured up top and the mini version are due within a few months.
