Bringing several systems into one app

Several emulator cores are connected so you can choose games and manage saves from the same library across systems.

Switching apps for each system and finding saves and settings again was cumbersome. In N-EMU, I wanted game files in one library and familiar menus regardless of the system.

Open-source emulator cores reproduce the hardware's behavior. By connecting mGBA, bsnes-jg, melonDS, ares and PPSSPP, N-EMU supports the same eleven systems on iOS and Android. That is possible thanks to the developers behind those cores.

Each core handles video, input and saves differently. N-EMU lets you import games and manage save states from the same menus, whichever core is running.

The controls unique to each system are not forced to be identical. DS needs two screens and touch; vertical WonderSwan games need a different orientation and button layout. Displays and controls reflect those differences.

Supporting a system does not mean every game runs equally well. The Features page lists the scope and limitations, and I intend to keep checking game startup, saving and resuming on real devices.
