This is an example application for github.com/blahness/nes.
github.com/blahness/nes/
github.com/DerelictOrg/DerelictSDL2/
For Windows there are stand-alone binary builds available at the GitHub release page. Note: they were compiled with DMD so they're not very optimized.
dub fetch nes_test
To run:
dub run nes_test --build=release -- <rom>
Or for a 64-bit version:
dub run nes_test --arch=x86_64 --build=release -- <rom>
<rom> should be the actual path of .nes rom to run
Clone or download this repo, cd to the folder that contains the source folder & run:
dub build --build=release
Or for a 64-bit version:
dub build --arch=x86_64 --build=release
If you're on Windows I'd also add --arch=x86_mscoff when using dub run or build to create 32-bit versions. The linker produces a very slow executable otherwise.
The app expects the SDL2 runtime binaries (minimum version 2.0.5) to be available. You can find them here: https://www.libsdl.org/download-2.0.php.
nes_test <rom>
Use nes_test -h for more options.
The app will create a save & state folder in its current directory on first run if they don't already exist. Battery backed RAM is saved only on program exit.
Joysticks are supported, although the button mapping is currently hard-coded. Keyboard controls are indicated below.
