Description. iNDS is a derivation of the previous Nintendo DS apps for iOS, nds4ios and Nitrogen. The original version, nds4ios, is a Nintendo DS emulator and a port of the multi-platform DeSmuME 0.9.10 for iOS. It runs many of the original games but, depending on the power of your device, not all may run at full speed. nds4ios was created by InfiniDev, a joint development group with many.
