GBA Movie Player
It looks like people are always finding new ways to make the Nintendo DS more useful, and here is another one.
The GBA Movie Player is an adapter that allows you to use a CF/SD card as storage for movies, or roms to play on your Nintendo DS or Gameboy Advance.
The M3 Adapter is one of the most powerful GBA(SP) and NDS accessories on the market. We use a standard CF/SD card so you’ll never have to worry about capacity again. Our device allows you to watch movies, listen to music, browse pictures, read e-books, and even play games! And our on-board Real-Time-Clock insures that every GBA game is compatible, unlike those other adapters. We’ve also gotten rid of the slowdown, so all the titles run at their real speeds.
