A geek friend of mine has just had this brought for him for Xmas and my jaw dropped, The Retroduo Portable has slots for the original carts, no need for emulation, your playing the real thing, the handheld plays Snes, Nes or even Sega Megadrive Carts and has an 8 hour battery life, heres a few of the specs:

The RetroDuo Portable is a finely made hand held gaming system. It allows you to play 16-bit SNES games and 8-bit NES games. The specifications are:
- Reinforced Cartridge

- Multi-player capabilities with two controllers

- Stand up your RPD or use it like a Handheld console

- Compatible with most 16-bit SNES games

- Compatible with most 16-Genesis games with the RetroGen Adapter (sold separately)

- Up to 8 Hours of uninterrupted gameplay with the Dual Capacity Lithium-Ion Battery

- Works with most Televisions

- Light-weight and Travel-friendly
Inside a freshly bought RetroDuo Portable package you will receive:
- Retro Duo Portable x 1

- SuperRetro Controller x 2

- Stand-up Dock x 1

- AC Power Adapter x 1

- AV Cable x 1

- Dual Capacity Lithium-Ion Battery x 1


Now if you partner this console with either a Neoflash Snes Cart or Neoflash Megadrive Cart then you have the ultimate console that can play perfectly just about any Snes/Megadrive or Nes Game, bloody mouthwatering
