App developer Riley Testut released AltStore, an alternative to Apple’s App Store. The iOS developer has worked on mobile game emulation for several years and has many open source projects. The AltStore distributes various apps including a Nintendo Emulator developed by Riley called Delta. This emulator lets users play classic games on their phones or tablets.
The developer's first emulation project called GBA4iOS was removed from the App Store. Now, Testut may have finally figured out a way for his software to stay indefinitely. The new Delta Emulator is a versatile app that lets users run and play games for Nintendo Entertainment System (NES), Super Nintendo Entertainment System (SNES), Game Boy (GB), Game Boy Advance (GBA), Nintendo 64 (N64), and Nintendo DS (NDS). While the emulator itself is far from perfect, it certainly satisfies the iPhone and iPad users craving for retro games.
The restrictions in iOS make emulations harder than on Android, but that very challenge is what inspired and motivated Testut. By utilizing a variety of exploits and tricks, Testut managed to find a way for users to install AltStore and the emulator Delta, without jailbreaking their device. This is made possible by tricking the phone into thinking that the users developed the app themselves - which is a clever idea.
