NO$GBA (No Cash Game Boy Advance) is a Game Boy Advance and Nintendo DS emulator for Microsoft Windows and MS-DOS. It supports most Nintendo DS homebrew, and a majority of commercial ROMs.
NO$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. However, since the emulator is a work in progress, options such as save states haven’t been implemented yet.
