It's a USB cart dumper and controller adapter sold by Dragonbox.de . The dumper presents itself as USB storage with a ROM file and the save files (that it extracts from the inserted cart). It supports SFC/SNES,and Genesis carts put of the box, but there are plugins for Gameboy, SMS, and N64 carts.Sorgelig wrote:Dynamic switch between SD and USB is not supported.
