Overview

Delta is the successor to a popular GBA emulator, GBA4iOS, made by the same developer and started development back in March of 2015. Similar to RetroArch, it uses a core-based approach with each system running off its own core, however it is not libretro-based and uses its own system to link into these cores. RetroAchievement support is in a beta phase for select cores (NES, SNES, N64), and all cores are planned in the future.

Supported systems

So far, only the NES, SNES, N64, GB(C), GBA and NDS systems are supported. Support for Sega Genesis emulation is planned for public release (1.8) with initial support added in a beta release (1.3b4). See here

Issues

In the European Union, sideloading is the only way to use Delta.[2]

People have had issues with ROM hacks where some refuse to boot, and others run improperly.

Delta's RetroAchievements support is problematic due to paywalling the feature, which led to the decision to delist Delta and disable hardcore support on 12 September 2025.
