Tap A to flap your wings and fly! The hit iOS game from 2013 is now available on N64!
Navigate a bird through a series of gaps and try not to hit the walls! This simple, one-button game is so easy to play that everyone will want a turn to see how far they can go!
This project is intended to be a complete example of a simple yet non-trivial game built for Nintendo 64 using the open source LibDragon SDK.
This project is considered "done", and is no longer being actively developed. It may receive occasional maintenance updates to ensure the code remains compatible with upstream changes in LibDragon.
- Faithful recreation of the original iOS game
- N64 RDP-accelerated graphics rendering
- N64 RSP-accelerated audio mixing
- 60FPS gameplay at 320x240 resolution
- Parallax background scrolling
- High score save support using EEPROM 4K
- Rumble Pak support
- Night sky is missing stars
- Screen does not shake upon death
Download or compile the ROM file and load it as you would any other N64 ROM.
This ROM file has been tested to work on real Nintendo 64 hardware using the EverDrive-64 by krikzz, 64drive by retroactive, and SummerCart64.
This ROM file should also be compatible with low-level, accuracy-focused Nintendo 64 emulators such as Ares, gopher64 and MAME.
Due to the usage of LibDragon, it is an explicit non-goal of this project to suppport emulators. The goal was to make a game for Nintendo 64, so tautologically:
If it works on the real console but not on the emulator, then the emulator is insufficiently accurate.
This project uses mise to manage the development environment and build tasks. Once mise is installed, run:
mise run setupThis will automatically initialize git submodules, build the N64 toolchain, and install LibDragon.
| Task | Alias | Description |
|---|---|---|
mise run setup |
Set up the complete development environment | |
mise run build |
mise run b |
Build the ROM |
mise run clean |
mise run c |
Clean build artifacts |
mise run ares |
Build and run the ROM in Ares emulator |
Additional lower-level tasks (usually run automatically by setup):
| Task | Description |
|---|---|
mise run submodules |
Initialize and update git submodules |
mise run toolchain |
Build the N64 GCC cross-compiler toolchain + GDB |
mise run libdragon |
Build and install LibDragon into the toolchain |
Run make to produce a ROM file from this source tree.
This project has been tested with the trunk branch of LibDragon:
git submodule update --init --recursiveRun the libdragon/tools/build-toolchain.sh and libdragon/tools/build-gdb.sh scripts to prepare a toolchain for LibDragon.
Then run the libdragon/build.sh script to install LibDragon in the toolchain.
The Makefile can be configured using the following environment variables:
N64_INST— Specify where your N64 GCC toolchain is installed.V=1— Enable "verbose" Make output; useful for troubleshooting.
Proper releases will be tagged as vX.Y where X is a major version number and Y is a minor version number.
