Treamcast - Wikipedia, the free encyclopedia

The Treamcast is an unauthorized third-party developed Dreamcast modification from China or Hong Kong that gained notability for its portability. Although there are several versions, all consist of modified internals from an original Dreamcast system, rehoused in a replacement case with a fold-down display resembling the screen produced for the PSone. As it uses original Sega parts, it is not strictly a clone console.
