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 emulator is currently in closed-beta and is undergoing thorough testing before its public release. The release is close! Riley set a tentative release of sometime before the end of Spring. But a release sometime in July seems more likely because the final beta has not been completed yet.

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. The frameworks are then implemented into the beautiful user interface created 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 App downloads will likely be run from this website upon Delta’s public release. The method to which you will install Delta is not being discussed at this time, but it will be as simple as clicking a button.
