Another World for Nintendo 64

Another World is a platforming, shooting, puzzle-solving game from the early 1990's released on many home computer and video game console platforms.

The project is a port of the Another-World-Bytecode-Interpreter game engine to N64 using the open source LibDragon SDK. The parent project targets SDL2, but was intentionally abstracted so that alternate system implementations could be provided based on the System struct. In this fork, SDL2 support has been retained, and N64 has been added as an additional CMake SYS_IMPLEMENTATION backend option.

This port is still unfinished and experimental with known bugs. Contributions are welcome.

Supported Versions

English PC DOS version is supported ("Out of this World"). You will need the original datafiles:

  • BANK*
  • MEMLIST.BIN

By default, the build scripts expect the datafiles to be in the ./game directory.

Compiling

N64

Prerequisites

Install libdragon

See https://github.com/DragonMinded/libdragon for instructions.

Compile and install zlib for libdragon

This game uses zlib to compress resources. It might make sense to decompress the files so that the N64 doesn't have to spend a bunch of time decompressing at run-time, but for the short term the simplest solution is to preserve the game files as-is.

You will need to download, cross-compile, and install zlib into your N64 SDK:

curl -O https://zlib.net/zlib-1.2.11.tar.gz
tar -xf zlib-1.2.11.tar.gz
cd zlib-1.2.11
prefix=${N64_INST}/mips64-elf CROSS_PREFIX=${N64_INST}/bin/mips64-elf- ./configure
make install

Build the ROM

Run bash buildN64.bash to build a release-optimized N64 ROM file. Inspect the build script for additional options.

This ROM file has been tested to work on real Nintendo 64 hardware using the EverDrive-64 by krikzz and 64drive by retroactive.

This ROM file should also be compatible with low-level, accuracy-focused Nintendo 64 emulators such as Ares, CEN64 and MAME.

Known issues

  • No title screen or menu
  • Saving is not implemented
  • Audio doesn't sound right

SDL2

Run bash buildSDL2.bash to build a native executable. Inspect the build script for additional options.
