3ds-ruby

Finally, a scripting language for the 3DS that is easy to install and embeddable!

Installing mruby

Compiling and installing mruby

Firstly, drag and drop the nintendo_3ds.rb onto mruby's build_config folder and then run the following commands (assuming you are onto the mruby's project folder):

# Clear the screen to make it nicer.
clear
# Firstly, compile and install the system's mruby.
sudo ./minirake all
# Now, we compile 3DS's mruby.
sudo ./minirake MRUBY_CONFIG=nintendo_3ds all
# Copy the recently compiled library folder to portlibs.
sudo cp -r build/nintendo_3ds_devkitARM/lib /opt/devkitpro/portlibs/3ds/.
# Copy the mruby's include folder to portlibs.
sudo cp -r include /opt/devkitpro/portlibs/3ds/.

If something went wrong you can do rake clean and recompile everything.
NOTE: i did not put all gems to compile (because some gems won't compile). You can add your own gem with conf.gem by modifying the nintendo_3ds.rb file.

Using the Project

Compiling this Project

This is the command i use to run the project:

clear;make clean;make&&flatpak run org.citra_emu.citra 3ds-ruby.3dsx

NOTE: the Makefile will convert all ruby code inside the source folder. If you are NOT going to use bytecode, see the next header.

Using compile

To use compile instead of bytecode, open nintendo_3ds.rb and uncomment conf.gem :core => 'mruby-compiler'.
Now open main.c and change mrb_load_irep_file(mrb, f) to mrb_load_file(mrb, f).
Remember to also change the file path, and move the main.rb to the romfs folder.
