MeloNX

MeloNX is a free, open-source Nintendo Switch emulator for iPhone and iPad, based on Ryujinx and licensed under GPLv3. It does not require a jailbreak, but it requires JIT and cannot run without it. The recommended installation guide uses PlumeImpactor to sideload the MeloNX IPA, with SideStore as an optional on-device sideloading route. The maker recommends iPhone 15 Pro or newer and certain iPad Pro and iPad Air models. Its lowest compatible devices are listed as iPhone 6s with a paid developer account and iPhone 12 with a free developer account. Users add encryption keys and firmware through the in-app file picker; commercial games require legally dumped firmware and keys, plus purchased games. Audio output is supported, while microphone input is not. Controls include keyboard, touch, JoyCon, and nearly all MFI controllers, though JoyCon motion support is unavailable due to an iOS limitation. MeloNX supports DLC and game update add-ons; mods are unsupported but may work. Graphics use Metal through MoltenVK to emulate the Switch Maxwell GPU. Settings include logging, controller remapping, resolution, and shader cache options. The project links to Discord for support.

MeloNX offers Switch emulation on iPhone and iPad, with controller options, audio output, DLC, and game updates. JIT is required, and commercial games require legally dumped firmware and keys along with purchased games.

MeloNX may suit iPhone and iPad users who can meet its JIT requirement and have compatible game files. The maker recommends newer iPhone and certain iPad models for use.

MeloNX is an open-source Nintendo Switch emulator for iPhone and iPad, built for users comfortable with sideloading and configuring JIT. It suits technically confident iOS players who already own legally dumped games and the required system files. The price is straightforward; the installation and runtime requirements are not.

Overview

MeloNX brings Switch emulation to Apple mobile hardware without requiring a jailbreak. The recommended setup uses PlumeImpactor to sideload the MeloNX IPA, with SideStore offered as an optional on-device sideloading route. JIT is mandatory and the emulator cannot run without it, so this is not an install-and-play choice for casual users.

The project is free and open source, based on Ryujinx and licensed under GPLv3. Its maker supports the project through a Discord server. Commercial games still require legally dumped firmware, encryption keys, and purchased game files; MeloNX does not provide those materials.

Key features

Graphics emulation uses Metal through MoltenVK to reproduce the Switch Maxwell GPU. Resolution and shader-cache controls let users tune rendering behavior, while logging can help diagnose problems and controller remapping accommodates different layouts. These settings provide useful adjustment room, but they add configuration work rather than removing it.

Input support covers keyboard, touch, JoyCon, and nearly all MFI controllers. That breadth makes MeloNX workable for both handheld and gamepad play. JoyCon motion controls are unavailable because of an iOS limitation, however, so motion-focused games are a poor match. Audio output is fully supported, while microphone input is not; titles or features that depend on microphone capture will therefore be limited.

DLC and game-update add-ons are supported. Mods are unsupported, although some may function, so players who depend on a reliable modding workflow should choose another emulator. Keys and firmware are imported through the in-app file picker, keeping those files under the user's control.

Pricing

MeloNX has one plan, MeloNX, priced at free. The plan includes the open-source Nintendo Switch emulator for iPhone and iPad, with no paid tier and no free trial. There are no subscription renewals or seat limits to weigh; the trade-off is the time required for sideloading, JIT configuration, and legally supplying game data.

Because every feature is in the free plan, paying for an upgrade is not an option for simplifying setup or adding capabilities. Users who want a no-cost iOS emulator and can handle the technical prerequisites get the complete product, while anyone unwilling to manage JIT will find the zero price less meaningful.

Platforms

MeloNX supports iOS on iPhone and iPad. The maker recommends iPhone 15 Pro or newer, along with certain iPad Pro and iPad Air models. Compatibility extends as low as iPhone 6s with a paid developer account and iPhone 12 with a free developer account, but those lower-end paths carry account requirements and are not the recommended hardware target.

Who it's for

MeloNX is for iPhone and iPad owners who understand sideloading, can arrange JIT, and have legally dumped firmware, keys, and purchased games. It is also a sensible fit for players who value open-source software, want to use MFI or JoyCon controllers, or need DLC and game-update support.

Look elsewhere if you need microphone input, dependable JoyCon motion controls, supported mods, or a setup that works without technical intervention. Users on Android, desktop systems, or other platforms will need a different emulator.

Verdict

Choose MeloNX if you want free, open-source Switch emulation specifically on an iPhone or iPad and are prepared to manage JIT, sideloading, and your own legally dumped game files. Its controller variety, Metal-based graphics settings, DLC support, and update support are strong reasons to use it.
