MD 16-BIT Chinese megadrive clone of Columbus Circle's handheld

A quick review of the MD 16-BIT handheld that costs 55$. A few notes : - No shadow & highlight unless you use composite (or svideo mod) - The cartridge slot had a dangling wire, had to use a piece of tape. - Master system does work but some have sprite issues. - I found only one instance of a game not booting (gasega68k's raycaster example)
