MeloNX

Description

MeloNX MeloNX enables Nintendo Switch game emulation on iOS using Ryujinx as a base. MeloNX is an iOS Nintendo Switch emulator based on Ryujinx, written primarily in C# and Swift. Designed to bring accurate performance and a user-friendly interface to iOS, MeloNX makes Switch games accessible on Apple devices. Developed from the ground up, MeloNX is open-source and available on Github under the GPLv3 license. FAQ Where's the prod.keys file?/Where can I download [game]? We do not support piracy, It is forbidden to request copyrighted content (Firmware/Games/Keys/Shaders) on our repositories or on the MeloNX Discord. Do I need a Switch to use this emulator? MeloNX emulator is capable of running many homebrew applications, and can be a crucial tool in the development and debugging of homebrew applications and games. To play commercial games, you will need access to a Switch compatible with custom firmware (CFW), which will enable you to dump your system firmware, keys and legally purchased games. How can I dump my firmware/games/keys? First, you need to hack your Nintendo Switch, which you can learn how to do here: https://nh-server.github.io/switch-guide/. Once you have hacked your Switch, backed up your keys and dumped your firmware, you may follow these guides to dump keys, updates and DLC, firmware and games: Keys Games, Updates and DLC Firmware Info A Paid Developer account or TrollStore may be needed for specific devices (Read about Entitlements below) MeloNX REQUIRES JIT and CANNOT run without it. Recommended iPhone: iPhone 15 Pro+ (8/12GB RAM both have the same memory limit of 6GB) Recommended iPad: iPad Pro 5th+ 128GB+ (8GB RAM) / 1TB+ (16GB RAM) or iPad Air 5+ (8GB RAM) Lowest Compatible Device (Paid Developer Account): iPhone 6s (iOS 15) Lowest Compatible Device (Free Developer Account): iPhone 12 Entitlements Entitlements are the underlying security permissions that allow an app to access specific features of your device MeloNX can use 2 Entitlements: Increased Memory Limit: - This allows MeloNX to be able to use the most amount of ram apple lets us. Extended Virtual Addressing: - This allows MeloNX to be able to ask iOS for more memory / RAM then actually available. - Extended Virtual Addressing is a PAID entitlement, TrollStore also gives this entitlement. Increased Memory Limit is required for all devices. Extended Virtual Addressing is required for specific devices which don't allow us to ask the RAM we need without the Extended Virtual Addressing entitlement. Those Devices include: iPads with less than 8GB of RAM. iPhones with less than 4GB of RAM. Discord Server We have a discord server! - https://discord.gg/HjCDPTpC3W How to install Recommended Guide (Plumeimpactor) SideStore is recommended (optional) for an on-device Sideloader, and should be installed prior performing this install. Make sure to read the FAQ and Info before continuing. 1. Sideload Application Download and install MeloNX using PlumeImpactor on a computer. - Download MeloNX From Releases - Open PlumeImpactor > Click Settings > Click Login - Login with the same Apple ID you are using for SideStore (or AltStore). - Import the MeloNX .ipa you downloaded earlier. - Plug in your iDevice. - Select your iDevice from the dropdown at the top of the window. - Click Install. 2. Load Into SideStore (Optional) To have MeloNX show inside SideStore (or AltStore), You must re-install it: - Open SideStore on your iDevice - Select the My Apps tab > Tap the + button. - Select the MeloNX .ipa (You may need to download it again.) - Wait for it to Sideload, then it should show up Inside SideStore. - Now You can Refresh MeloNX and Update it without needing a computer. 4. Setup Files Add Encryption Keys and Firmware using the file picker inside MeloNX, Information for where to get these files are here 5. Enable JIT Enable JIT using your preferred method, on iOS 26 StikDebug is required. Paid Developer Account (Legacy) Make sure to read the FAQ and Info before continuing. 1. Sideload MeloNX Download and install MeloNX using your preferred Apple ID (NOT CERT) sideloader: - Download MeloNX from Releases 2. Enable Memory Entitlement Visit Apple Developer Identifiers. Locate MeloNX and enable the following entitlements: Increased Memory Limit Extended Virtual Addressing Increased Debugging Memory Limit 3. Reinstall MeloNX Delete existing MeloNX installation Sideload MeloNX again Verify Increased Memory Limit is enabled in app 4. Setup Files Add Encryption Keys and Firmware using the file picker inside MeloNX Information for where to get these files are here 5. Enable JIT Enable JIT using your preferred method, on iOS 26 StikDebug is required. Free Developer Account (Legacy, On-Device) SideStore is recommended to Sideload MeloNX. Make sure to read the FAQ and Info before continuing. The Entitlement App is *NOT needed for AltStore Classic*** - You may skip Step 2 and Step 3 1. Sideload Applications Download and install both apps using your preferred APPLE ID sideloader: - MeloNX: Download from Releases - Entitlement App: Download IPA 2. Enable Memory Entitlement If the Entitlement / GetMoreRam app isn't working correctly, then try the new Plumeimpactor method. - Open the Entitlement app > Settings - Sign in with the same Apple ID you used to Sideload MeloNX. - Go to App IDs > tap Refresh - Select MeloNX (e.g., "com.stossy11.MeloNX.XXXXXX") - Tap Add Increased Memory Limit 3. Reinstall MeloNX Delete existing MeloNX installation Sideload MeloNX again Verify Increased Memory Limit is enabled in app 4. Setup Files Add Encryption Keys and Firmware using the file picker inside MeloNX Information for where to get these files are here 5. Enable JIT Enable JIT using your preferred method. We recommend StikDebug. Features - Audio Audio output is entirely supported, audio input (microphone) isn't supported. We use C# wrappers for OpenAL, and SDL2 & libsoundio as fallbacks. - CPU The CPU emulator, ARMeilleure, emulates an ARMv8 CPU and currently has support for most 64-bit ARMv8 and some of the ARMv7 (and older) instructions, including partial 32-bit support. It translates the ARM code to a custom IR, performs a few optimizations, and turns that into x86 code. There are three memory manager options available depending on the user's preference, leveraging both software-based (slower) and host-mapped modes (much faster). The fastest option (host, unchecked) is set by default. Ryujinx also features an optional Profiled Persistent Translation Cache, which essentially caches translated functions so that they do not need to be translated every time the game loads. The net result is a significant reduction in load times (the amount of time between launching a game and arriving at the title screen) for nearly every game. NOTE: This feature is enabled by default, You must launch the game at least twice to the title screen or beyond before performance improvements are unlocked on the third launch! These improvements are permanent and do not require any extra launches going forward. - GPU The GPU emulator emulates the Switch's Maxwell GPU using Metal (via MoltenVK) APIs through a custom build of Silk.NET. - Input We currently have support for keyboard, touch input, JoyCon input support, and nearly all MFI controllers. Motion controls are natively supported in most cases, however JoyCons do not have motion support due to an iOS limitation. Rumble is also natively supported in most cases. - DLC & Modifications MeloNX supports DLC + Game Update Add-ons. Mods (romfs, exefs, and runtime mods such as cheats) are unsupported; but may work. - Configuration The emulator has settings for enabling or disabling logging, remapping controllers, resolution settings, Shader Cache and more.
