Kode has compiled the Joyau version 0.8 EBOOT for anyone coding on the Ruby train and cannot or do not care to compile their own from source. If you’re not clear, see our previous Joyau news for a better understanding.

Calling all devs, especially those well-versed in Ruby. Welcome to the game — Kode’s Joyau (read: Jewel, in English).

Joyau is a Ruby interpreter for the PlayStation Portable. Similar to that of Lua you’ll code in Ruby and crunch that code using the supplied EBOOT, which acts as the script interpreter. Kode notes the documentation is currently incomplete; however, you can learn how things work by trial and error and using the provided samples.

Things you may need and/or should know:

1. Copy the “script.rb” file (your Ruby code) into the same directory as the Joyau EBOOT.
2. The Joyau EBOOT is compiled with PSP_FW_VERSION = 371.
3. Try LEDA or Time Machine if you’re experiencing problems with executing the EBOOT.

Current features:

• A working sprite system;
• A particles generator (just a front end to the devslib one in fact);
• A scrolling class;
• Some audio function (really basic though, I’ve to work on that… I’ll try with OpenAL to provide ogg support at least);
• Also, text manipulation (drawing text, …);
• Possibility to draw basic forms (Circle, rect, …);
• Some things provided by Ruby itself.
