Delta Emulator is an iOS multi-system emulator written from the bottom up by Riley Testut, the previous lead developer of popular emulator, GBA4iOS.

The actual "emulators" are not found in this framework because Delta was designed to be extremely modular. Each system that Delta can emulate has its own framework that contains the emulation core. Those frameworks are then implemented by this main framework. The links to each separate github repository can be found on the sidebar to the right. On this note, please report system-specific bugs to their corresponding repository (Ex. Pokémon Emerald bug/glitch goes to GBA).

Delta Emulator’s official website is and is downloadable from the AltStore.
