New Super Mario Bros. E3 2005 demo recreation

This is a recreation of the New Super Mario Bros. demo featured at E3 2005 (and other events in 2005). There's still a lot more to do, but it should be fully playable in single player and multiplayer, and various code hacks are implemented.

To enter the multiplayer mode, press B on the menu. Only multi-cart/multi-ROM play works, not download play.

See Download and usage.

• Discord server (discussion and small previews)
• NSMBHD thread (discussion, plus videos and more screenshots)

FAQ

How can I help?
What we most need at the moment is more photos and videos of the demo, and more info from people who played the demo. Please tell us if you think you may be able to help, or know somebody who may be able to help. Here is a (messy) page containing the info we currently have: https://tcrf.net/Prerelease:New_Super_Mario_Bros./2005/Demo

When will the finished recreation be released?
There is no estimated release date.

Does the recreation aim to be fully accurate to the demo?
Yes, but this is currently limited by the amount of footage and information we have of/on the demo.

When will the next update be?
The project is still ongoing - there isn't really any reason to discontinue it, except if the real demo was leaked. There is a code refactor branch, which includes some new features, and there are some asset improvements in the to_implement folder, but both of those haven't been touched for a while. There isn't a schedule for updates, and it depends on free time and motivation. However the assets are low-hanging fruit if someone wants to make a pull request.

Download and usage

Download the patch from releases

Try the xdelta2 file first - if that doesn't work, try the xdelta3 file.

Patching tools for different platforms (in order of ease of use):

• https://www.marcrobledo.com/RomPatcher.js/ (javascript web app, only works with xdelta2 files)
• https://kotcrab.github.io/xdelta-wasm/ (webassembly web app, only partial xdelta3 support?)
• https://github.com/btimofeev/UniPatcher (Android)
• https://github.com/marco-calautti/DeltaPatcher/releases (Windows)
• https://github.com/dan0v/xdelta3-cross-gui/releases (Windows, Mac, Linux)
• https://github.com/jmacd/xdelta-gpl/releases (Windows, Mac, Linux) (command line program)

You should patch a clean NSMB USA ROM².

Playing

At least one version has been successfully tested on the following:

• DeSmuME
• MelonDS
• nds-bootstrap using the TWiLight Menu++ frontend
• R4i-SDHC 3DS RTS flashcard (default firmware)
• Acekard 2i (AKAIO)
• Wii U's Nintendo DS Virtual Console (hachihachi)
• M3 DS Real (ysmenu)

It should work on all DS and 3DS consoles.

Known issues

Bugs are documented here: https://github.com/mariomadproductions/nsmb-e3-rec/issues

Workarounds/unimplemented things that may seem like bugs:

• No sound effect for wall jumping
• No Mega Goomba in the Field level
• Static lifts instead of lift spawner at start of Fortress
• No Whomps in the Fortress level
• "! Switch"-activated coins in the Desert level can't be collected

There are of course many other unimplemented things, that are obviously just not implemented yet.

Building

Prerequisites:

• Git
• GNU Arm Embedded Toolchain
• GNU Make
• Python 3
• ndspy
• NSMBe (v5.3 or later)
• NitroSDK (tested with NitroSDK-3_0-060125¹)
• Clean NSMB USA ROM²

Note: On Windows, you can install msys2 and then use pacman to get GNU Arm Embedded Toolchain, GNU Make etc. Alternatively, you can install the devkitPro "nds-dev" component, which includes its own versions of those.

Steps:

• Clone the repo.
• Go into the repo folder.
• Copy the NitroSDK include folder contents into the repo include folder.
• Run convert_sdk.py.
• Place the ROM as rom.nds in the repo.
• Run insert_files.py rom.nds.
• Open rom.nds in NSMB Editor.
• Go to the Tools/Options tab and click Run 'make' and insert. If you get a error message box just click continue.

Tools used

In addition to those listed in the build instructions.
