You do realize that's a strong chance for Nintendo to take it down. You can't post fan-made games on copyrighted characters to the App Store or Google Play.
So you don't. Besides, Super Mario 127 is open-source as of now and can essentially be run on the latest versions of the Godot mobile editor and be exported as an APK, as the Godot mobile editor now supports that and it's confirmed that Super Mario 127 runs well on mobile. APKs still follow the rules of package formats on many systems, such as regular Linux or Winget; you can either install them from some sort of link (such as a repository) or from a file. APKs also do not need to be published to a storefront because of this.
