Super Mario Bros. 35

NSW

Turns your own dump of Super Mario Bros. 35 into a native program for macOS, Windows and Linux (iOS, iPadOS and Android from source): the game’s code is translated to C and compiled for your machine, its system calls run on a native runtime, and its graphics run on Metal or Vulkan. It isn’t an emulator. It is a fork of SMM2 Recomp, which shares its runtime and recompiler. The online service comes from Nextendo Network, a community server: sign-in, 35-Player Battle matchmaking, the battle relay and the results are implemented, and Course Practice, Special Battle and Daily Challenges work. The authors tested two-player matches through to the final ranking on a Mac and an iPad; Windows and Linux build but haven’t been tried on real hardware. v0.4.0 is from October 21. All 63 of its commits list Claude as a co-author.

You needYour own copy of Super Mario Bros. 35 with the 1.0.2 update (the NSP or XCI files, or the extracted ExeFS and RomFS folders), plus the prod.keys and firmware from your console, which are only read and never copied. A free Nextendo Network account with a linked Discord is needed, even for Course Practice. macOS 15 or newer on Apple silicon (Metal), or Windows 10/11 x86-64 with AVX2, or Linux with Vulkan 1.3.
