SMM2 Recomp (Super Mario Maker 2 PC port)

Super Mario Maker 2 came out on the Nintendo Switch in June 2019 and has never been released on PC. The GitHub account smm2recomp created the repository on 19 October 2026, published version 0.2.0 on 20 October and four more releases on 21 October, up to 0.3.2. It had just over 100 stars when we checked. The account is new and gives no name, website or social links, and we found no press coverage yet.

What it is

• A static recompilation: the game’s AArch64 code is translated to C ahead of time and compiled for your system. A native runtime stands in for the Switch’s system services, and the graphics (Nintendo’s NVN API) run on Metal on Apple devices and Vulkan elsewhere.
• Recompiled on your machine: a download holds only the launcher and the recompiler with a bundled compiler. The first start extracts your files, copies the fonts from your firmware and recompiles the game code, which takes a few minutes to half an hour.
• Forked from LAS Recomp: the recompiler started as a fork of the Link’s Awakening recompilation (MIT). The project itself is GPL-3.0.
• Source in the repository: the recompiler (Python), runtime (C and Objective-C) and course server (Rust) are all there, about 190 commits on 21 October 2026. A CI check blocks game files from being committed.
• AI help: the README says nothing about it, but 85 of the last 100 commits list Anthropic’s Claude as co-author.

It works like the other console recompilations in our recompiled games list.

Current status

From the README and release notes:

• Title, menus, course play and Course Maker test play work, with fidelity work ongoing. The README reports in-course frames pixel-identical to Ryujinx in 71 of 90 style and theme combinations on the Mac.
• 100 Mario Challenge from Super Mario Maker 1 is playable start to finish, ending and credits included.
• Endless Challenge plays against the course server.
• Course World: lists, search, download, play and leaderboards work; likes, comments and uploads are in progress.
• SMM1 features as mods, each with its own switch, such as Mystery Mushroom costumes and mid-air shell jumps, are in progress.
• 0.2.0 added shader prefetch to cut first-time stutter and an experimental 120 fps frame generation mode.

Known problems: the first 17 GitHub issues, all opened on 20 and 21 October, are mostly setup failures (applying the 3.0.3 update, “the game code didn’t build”) and Windows crashes, plus slow performance on the Steam Deck and a report that newer firmware doesn’t work. 0.3.2 fixed the update step for NSP and XCI files. We didn’t play it ourselves.

Online and course sharing

Nintendo’s servers are not used. Instead the game talks to an open-source course server that anyone can host (instructions are in the repository), which holds accounts, courses, leaderboards and challenge runs and can import courses from TGRCode’s public archive. On iOS a copy of the server runs inside the app. The README doesn’t name a public server run by the project, so check the repository for where to connect. Online multiplayer is planned, with network groundwork in progress.

What you need

• Your own dump of Super Mario Maker 2 with the 3.0.3 update: the game’s NSP or XCI and the update’s NSP, or extracted ExeFS and RomFS folders. The launcher checks your files against known 3.0.3 hashes.
• Your own console’s prod.keys and firmware. The README says they are read in place, never copied, and key values are never logged. We don’t explain how to obtain any of these.
• Optionally Super Mario Maker on Wii U, for the SMM1 mods.
• Windows 10/11 on x64 with an AVX2 CPU and a Vulkan 1.3 driver; Linux x64 or arm64 with SDL3 3.2+ and Vulkan 1.3 (Debian 13, Ubuntu 25.04, Fedora 41, Arch or newer); or macOS 15+ on Apple silicon.
• iPhone, iPad and Android have no download: you build them from source, and iOS needs a Mac to build, sign and install.

How to install

At a high level, from the official README: download your system’s package from the project’s GitHub releases, unpack it somewhere writable and start it, point the setup screen at your dump, keys and firmware, and let it set up and recompile the game. Later starts go straight to the game. The Mac app isn’t notarized, so the first start needs right-click and Open. If something fails, the README asks for the log files in a GitHub issue; they contain no key values.

Is it legal and safe?

• It is an unofficial fan project, not affiliated with or endorsed by Nintendo. The README says no Nintendo code or assets are distributed, and asks you to use a legally obtained copy. One GitHub issue raises the legal questions around needing prod.keys.
• The maintainer is anonymous and the project is days old. Releases include SHA-256 checksums; get them only from the official GitHub repository. Sites offering a “Super Mario Maker 2 PC download” with the game included are not this project.
