Super Mario 64 Nintendo 3DS Port

This repo does not include all assets necessary for compiling the game. A prior copy of the game is required to extract the assets.

Changes vs. Vanilla 3DS Port

• Based off Refresh 11
• Stereo 3D support; use the mini-menu to switch between 3D (400px) and 800px modes (800PX/AA disabled in 3D mode)
• Multi-threaded; audio thread runs on Core 1 on O3DS and Core 2 on N3DS; needs Luma v10.1.1 or higher
• Naïve frame-skip if frame takes longer than 33.3ms (1 / 30 FPS) to render. This option is no longer very useful, but is still available for posterity.
  • Enable by building with ENABLE_N3DS_FRAMESKIP=1
• Enhanced RSP Audio emulation performance
  • Disable some minor performance enhancements by building with DISABLE_ENHANCED_RSPA=1. This should not impact quality, but may be useful for debugging.
  • Use the PC port's original audio emulation by building with FORCE_REFERENCE_RSPA=1. This should not impact quality, but may be useful for debugging, and will override DISABLE_ENHANCED_RSPA.
  • By default, 3DS audio uses some inaccurate math to increase performance with no perceptible loss in quality. To disable this, build with AUDIO_USE_ACCURATE_MATH=1. This may have no effect depending on the audio implementation being used; for example, Reference RSPA ignores this flag.
• Configurable controls via sm64config.txt
  • See 3DS_CONTROLLER_REMAPPING.md.
• GFX_POOL_SIZE fix (support 60 FPS on 32bit platforms)
• Mini-menu (tap touch-screen to trigger)
  • Enable/disable AA
  • Enable/disable 800px mode
  • Exit the game
• Touch-screen camera controls similar to SM64DS
• Support injection of SMDH file into the .3dsx
  • Change the 3ds/icon.png in the base of this repository before building.
• To change the CIA banner, modify the 3ds/icon.png and 3ds/banner.png and use bannertool to generate new icon.icn and banner.bnr respectively.
• Patches updated for 3DS:
  • 60 FPS
  • Puppycam
  • Show FPS
• Choice to disable audio at build-time; add build flag DISABLE_AUDIO=1

Building

After building, either install the .cia if you made one, or copy over the sm64.us.f3dex2e.3dsx into the /3ds directory on your SD card and load via The Homebrew Launcher.

After making any changes to your build flags, it is important to run make clean before rebuilding, or else the new flags will not be applied.

• Docker
• Linux / WSL (Ubuntu 18.04 or higher)
• Windows (MSYS2)

Visit the wiki for information.

Docker

The following assumes a basic understanding of Docker; if you do not belong to the docker group, prefix those commands with sudo.

As of recently, using Docker Desktop for Windows and WSL2 has become the easiest way to build when using WSL. For more information, look here.

Clone Repository:

git clone https://github.com/mkst/sm64-port.git

Navigate into freshly checked out repo:

cd sm64-port

Copy in baserom.XX.z64:

cp /path/to/your/baserom.us.z64 ./ # change 'us' to 'eu', 'jp' or 'sh' as appropriate

Build with pre-baked image:

Change VERSION=us if applicable.

docker run --rm -v $(pwd):/sm64 markstreet/sm64:3ds make --jobs 4 VERSION=us cia 

Linux / WSL (Ubuntu)

As of recently, using Docker Desktop for Windows and WSL2 has become the easiest way to build when using WSL. For more information, look here.

Tested successfully on Ubuntu 18.04 and 20.04. Does not work on 16.04.

Windows (MSYS2)

WSL is the preferred route, but you can also use MSYS2 (MINGW64) to compile.

For each instruction copy and paste the contents into the MING64 console.

Get MSYS2:

Navigate to https://www.msys2.org/ and download the installer.

Install and Run MINGW64:

Next, Next, Next, Finish (keep the box checked to "Run MSYS 64bit now").

Add keyserver for package validation:

pacman-key --recv BC26F752D25B92CE272E0F44F7FD5492264BB9D0 --keyserver keyserver.ubuntu.com
pacman-key --lsign BC26F752D25B92CE272E0F44F7FD5492264BB9D0

Add DevKitPro keyring:

pacman -U --noconfirm https://downloads.devkitpro.org/devkitpro-keyring.pkg.tar.xz

Add DevKitPro package repositories:

cat <<EOF >> /etc/pacman.conf
[dkp-libs]
Server = https://downloads.devkitpro.org/packages
[dkp-windows]
Server = https://downloads.devkitpro.org/packages/windows
EOF

Update dependencies:

pacman -Syu --noconfirm

MINGW64 may close itself when done, if it does, find MSYS2 MinGW 64bit in your Start Menu and open again.

Install Dependencies:

pacman -S 3ds-dev git make python3 mingw-w64-x86_64-gcc unzip --noconfirm

Download makerom:

wget https://github.com/3DSGuy/Project_CTR/releases/download/makerom-v0.17/makerom-v0.17-win_x86_64.zip

Extract makerom:

unzip -d /opt/devkitpro/tools/bin/ makerom-v0.17-win_x86_64.zip

Setup Environment Variables:

export PATH="$PATH:/opt/devkitpro/tools/bin" && echo "OK!"
export DEVKITPRO=/opt/devkitpro && echo "OK!"
export DEVKITARM=/opt/devkitpro/devkitARM && echo "OK!"
export DEVKITPPC=/opt/devkitpro/devkitPPC && echo "OK!"

Clone Repository:

git clone https://github.com/mkst/sm64-port.git

Navigate into freshly checked out repo:

cd sm64-port && echo "OK!"

Copy in baserom.XX.z64:

This assumes that you have create the directory c:\temp via Windows Explorer and copied the Super Mario 64 baserom.XX.z64 to it.

cp /c/temp/baserom.us.z64 ./ && echo "OK!" # change 'us' to 'eu', 'jp' or 'sh' as appropriate

Compile 3dsx:

make VERSION=us --jobs 4 # Change 'us' to 'eu', 'jp' or 'sh' as appropriate.

Create .cia:

make VERSION=us cia # Change 'us' to 'eu', 'jp' or 'sh' as appropriate.

Other Operating Systems

TBD; feel free to submit a PR.
