no$gba emulator for NDS (Nintendo Dual Screen)

no$gba (Nocash Game Boy Advance) is a Game Boy Advance and Nintendo DS emulator for Microsoft Windows and MS-DOS. It supports most Nintendo DS homebrew, and a majority of commercial ROMs. NO$GBA includes a variety of options for emulation, including multiple save types, and multiple cartridge reading. It is able to load multiple GBA/NDS ROM files for the purpose of multiplayer functions.
