Treamcast © 200? Unknown [China].
The Treamcast is an unauthorised Sega Dreamcast modification which originated from China. It allows to play any Dreamcast games from any region of the globe, as well as CD-Rs and (with special software), MP3 and Video CD format
Despite being commonly labelled as a "clone", it used original Sega parts and as such is technically more of a modification than a clone in a regular sense.
It gained notability for being portable, being a smaller size than a regular Dreamcast console and having a fold-down LCD display.
