As a result, emulation is rather slow on older devices, like the iPhone 4s and below. This is because nds4ios’s emulation is powered by a threaded ARM interpreter. INDS supports all versions of iPad, iPhone, iPod Touch running between 8.1 and 9.2 except iPod touch 4, iPad 1, iPhone 3GS, and anything below those devices. iNDS, however, is mostly developed by William L Cobb. nds4ios was created by InfiniDev, a joint development group with many members including popular GBA4iOS creator Riley Testut upcoming Nightingale app developer Michael Zhang and PPSSPP iOS build manager Karen Tsai along with many others. It runs many of the original games but, depending on the power of your device, not all may run at full speed. The original version, nds4ios, is a Nintendo DS emulator and a port of the multi-platform DeSmuME 0.9.10 for iOS. INDS is a derivation of the previous Nintendo DS apps for iOS, nds4ios and Nitrogen.
