Hideous name, and less-than-hideous hardware. CYBER Gadget's "Familator Lite" plugs into a DS Lite's GBA slot, allowing users to insert their Famicom cartridges and re-live their favorite Nintendo classics in portable form.
Would rather re-live the classics on television? The device allows for TV out. Would rather play with the original Famicom controllers? Well... the device doesn't do that, actually. But it does that other stuff!
The Familator Lite is due out in Japan in December, but no price has been set. Sadly, the device's form factor means it's only compatible with the DS Lite, and not its phatter older brother.
