    How to play
    1. There is no build to download: get the code from the project's repository.
    2. Build it as its README says. What the build gives, a program to run or the original game rebuilt for an emulator, is written there too.
    3. The project's page says what it needs from your own copy of Super Mario Bros. 3, if anything.

From SubmitGame's list, read Oct 21, 2026, with releases, stars and licenses as each project's repository gives them. The steps are the same for every project of a kind: its own page has the details.

Under the hood: every project behind it, its license and code, how they connect, and who made them.
