Building cen64 on macOS
January 11, 2020
For testing Nintendo 64 homebrew ROMs, cen64 is the most accurate emulator (though it doesn’t run at full speed yet). Here’s how to build it from source on macOS:
- Install XQuartz from the official distributed disk image
git clone https://github.com/n64dev/cen64.git
If you’d like to enable cen64’s debug logging, create a debug build when running
cmake -DCMAKE_BUILD_TYPE=Debug ..
When running cen64 outside of an XQuartz X11 terminal, it may report:
Using NTSC-U PIFROM create_device: Failed to initialize the VI. Failed to create a device.
To fix this, you can run it within an XQuartz X11 terminal, or simply set the
DISPLAY environment variable to something like
:0 either in your
.bashrc file or inline during invocation:
DISPLAY=:0 ./cen64 /path/to/pifdata.bin /path/to/rom.z64
DISPLAY needs to be set because cen64 calls XOpenDisplay with a NULL display name (presumably to default to your
DISPLAY environment variable), but if it’s not set, XOpenDisplay returns NULL and cen64 has no display within which to create a window for rendering Nintendo 64 content.
For extremely verbose register-level output, edit
CMakeLists.txt and set
ON. Make sure to remove any cached data in
build/ to ensure your changes are reflected, then recompile and re-run.
