==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 of it's own core, however it is not the same as Libretro format. So far only the NES, SNES, N64, GB(C), and GBA are supported with NDS emulation currently in beta and only available to Patreon donors. Support for Sega Genesis emulation is planned for after NDS emulation is publicly released.

Due to Apple's unique philosophy on what is allowed to be on the App Store and limiting the ability to install third-party applications, installing the app can be a little bit complicated.  Luckily there are multiple ways of installing and you can even do it without needing to jailbreak your phone, such as the developer's App Store alternative, AltStore.

Most of the systems have great compatibility, with the exceptions of DS emulation. Both DS cores are slow and have low compatibility, and can sometimes crash, but turning off low power mode can help. All systems also can have sound problems, ranging from crackling to latency of a few seconds.

Overview

[edit | edit source]

Delta is the successor to a popular GBA emulator, GBA4iOS, made by the same developer and started development back in March of 2015. Similarly 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

[edit | edit source]

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

[edit | edit source]

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.
