      1 # Super Mario 64
      2 
      3 - This repo contains a full decompilation of Super Mario 64 of the following releases: Japan (jp), North America (us), Europe (eu), Shindou (sh) and iQue Player (cn).
      4 - Naming and documentation of the source code and data structures are in progress.
      5 
      6 It builds the following ROMs:
      7 
      8 * sm64.jp.z64 `sha1: 8a20a5c83d6ceb0f0506cfc9fa20d8f438cafe51`
      9 * sm64.us.z64 `sha1: 9bef1128717f958171a4afac3ed78ee2bb4e86ce`
     10 * sm64.eu.z64 `sha1: 4ac5721683d0e0b6bbb561b58a71740845dceea9`
     11 * sm64.sh.z64 `sha1: 3f319ae697533a255a1003d09202379d78d5a2e0`
     12 * sm64.cn.z64 `sha1: 2e1db2780985a1f068077dc0444b685f39cd90ec`
     13 
     14 This repo does not include all assets necessary for compiling the ROMs.
     15 A prior copy of the game is required to extract the assets.
     16 
     17 ## Quick Start (for Ubuntu)
     18 
     19 1. Install prerequisites: `sudo apt install -y binutils-mips-linux-gnu build-essential git pkgconf python3`
     20 2. Clone the repo from within Linux: `git clone https://github.com/n64decomp/sm64.git`
     21 3. Place a Super Mario 64 ROM called `baserom.<VERSION>.z64` into the project folder for asset extraction, where `VERSION` can be `jp`, `us`, `eu`, `sh`, or `cn`.
     22 4. Run `make` to build. Specify the version through `make VERSION=<VERSION>`. Add `-j4` to improve build speed (hardware dependent).
     23 
     24 Ensure the repo path length does not exceed 255 characters. Long path names result in build errors.
     25 
     26 ## Installation
     27 
     28 ### Windows
     29 
     30 Install WSL and a distro of your choice following
     31 [Windows Subsystem for Linux Installation Guide for Windows 10.](https://docs.microsoft.com/en-us/windows/wsl/install-win10)
     32 We recommend either Debian or Ubuntu 18.04 Linux distributions under WSL.
     33 Note: WSL1 does not currently support Ubuntu 20.04.
     34 
     35 Next, clone the SM64 repo from within the Linux shell:
     36 `git clone https://github.com/n64decomp/sm64.git`
     37 
     38 Then continue following the directions in the [Linux](#linux) installation section below.
     39 
     40 ### Linux
     41 
     42 There are 3 steps to set up a working build.
     43 
     44 #### Step 1: Install dependencies
     45 
     46 The build system has the following package requirements:
     47  * binutils-mips
     48  * pkgconf
     49  * python3 >= 3.6
     50 
     51 Dependency installation instructions for common Linux distros are provided below:
     52 
     53 ##### Debian / Ubuntu
     54 To install build dependencies:
     55 ```
     56 sudo apt install -y binutils-mips-linux-gnu build-essential git pkgconf python3
     57 ```
     58 
     59 ##### Arch Linux
     60 To install build dependencies:
     61 ```
     62 sudo pacman -S base-devel python
     63 ```
     64 Install the following AUR packages:
     65 * [mips64-elf-binutils](https://aur.archlinux.org/packages/mips64-elf-binutils) (AUR)
     66 
     67 ##### Other Linux distributions
     68 
     69 Most modern Linux distributions should have equivalent packages to the other two listed above.
     70 You may have to use a different version of GNU binutils. Listed below are fully compatible binutils
     71 distributions with support in the makefile, and examples of distros that offer them:
     72 
     73 * `mips64-elf-` (Arch AUR)
     74 * `mips-linux-gnu-` (Ubuntu and other Debian-based distros)
     75 * `mips64-linux-gnu-` (RHEL/CentOS/Fedora)
     76 
     77 You may also use [Docker](#docker-installation) to handle installing an image with minimal dependencies.
     78 
     79 #### Step 2: Copy baserom(s) for asset extraction
     80 
     81 For each version (jp/us/eu/sh/cn) for which you want to build a ROM, put an existing ROM at
     82 `./baserom.<VERSION>.z64` for asset extraction.
     83 
     84 ##### Step 3: Build the ROM
     85 
     86 Run `make` to build the ROM (defaults to `VERSION=us`).
     87 Other examples:
     88 ```
     89 make VERSION=jp -j4       # build (J) version instead with 4 jobs
     90 make VERSION=eu COMPARE=0 # build (EU) version but do not compare ROM hashes
     91 ```
     92 
     93 Resulting artifacts can be found in the `build` directory.
     94 
     95 The full list of configurable variables are listed below, with the default being the first listed:
     96 
     97 * ``VERSION``: ``jp``, ``us``, ``eu``, ``sh``, ``cn``
     98 * ``GRUCODE``: ``f3d_old``, ``f3d_new``, ``f3dex``, ``f3dex2``, ``f3dzex``
     99 * ``COMPARE``: ``1`` (compare ROM hash), ``0`` (do not compare ROM hash)
    100 * ``NON_MATCHING``: Use functionally equivalent C implementations for non-matchings. Also will avoid instances of undefined behavior.
    101 * ``CROSS``: Cross-compiler tool prefix (Example: ``mips64-elf-``).
    102 
    103 ### macOS
    104 
    105 With macOS, you may either use Homebrew or [Docker](#docker-installation).
    106 
    107 #### Homebrew
    108 
    109 #### Step 1: Install dependencies
    110 Install [Homebrew](https://brew.sh) and the following dependencies:
    111 ```
    112 brew update
    113 brew install coreutils make pkg-config tehzz/n64-dev/mips64-elf-binutils
    114 ```
    115 
    116 #### Step 2: Copy baserom(s) for asset extraction
    117 
    118 For each version (jp/us/eu/sh/cn) for which you want to build a ROM, put an existing ROM at
    119 `./baserom.<VERSION>.z64` for asset extraction.
    120 
    121 ##### Step 3: Build the ROM
    122 
    123 Use Homebrew's GNU make because the version included with macOS is too old.
    124 
    125 ```
    126 gmake VERSION=jp -j4       # build (J) version instead with 4 jobs
    127 ```
    128 
    129 ### Docker Installation
    130 
    131 #### Create Docker image
    132 
    133 After installing and starting Docker, create the docker image. This only needs to be done once.
    134 ```
    135 docker build -t sm64 .
    136 ```
    137 
    138 #### Build
    139 
    140 To build, mount the local filesystem into the Docker container and build the ROM with `docker run sm64 make`.
    141 
    142 ##### macOS example for (U):
    143 ```
    144 docker run --rm --mount type=bind,source="$(pwd)",destination=/sm64 sm64 make VERSION=us -j4
    145 ```
    146 
    147 ##### Linux example for (U):
    148 For a Linux host, Docker needs to be instructed which user should own the output files:
    149 ```
    150 docker run --rm --mount type=bind,source="$(pwd)",destination=/sm64 --user $UID:$GID sm64 make VERSION=us -j4
    151 ```
    152 
    153 Resulting artifacts can be found in the `build` directory.
