19:30 〜 20:00 Cross-platform mruby on Sega Dreamcast and Nintendo Wii Yuji Yokoo

Do you remember Nintendo Wii? It was a very successful video game console released in 2006. You can now write mruby code that runs on Nintendo Wii, with no hardware modification required. As mruby runs on Sega Dreamcast too, now you can write mruby code that runs on both Dreamcast and Wii (with caveats).

I have ported the mruby block puzzle game I wrote for Dreamcast to Wii, and now I am porting the presentation application I used to present on Dreamcast at RubyKaigi Takeout 2020. The aim is to run the same mruby code on those 2 platforms with no or little modification.

In this presentation, I will show you how I have done / am doing the porting work, and how you can write your own cross-platform mruby code for those 2 platforms.

This presentation was originally given at RubyKaigi 2024.


Yuji is a software developer who has lived for a long time in Adelaide, Australia but is now based in Tokyo. He used to be a Windows desktop application developer until he discovered Ruby. Besides programming, he enjoys video games and Brazilian Jiu Jitsu.

20:00 〜 20:30 Rubyist show and tell

Do you have a cool snippet of Ruby code that you'd like to share, but it doesn't warrant an entire presentation? A challenge with your Ruby application you've been struggling with, and would like some advice? A helpful library or tool you've come across? This is your chance to share it.

For those who'd like to participate, you'll have up to five minutes. There's no need to create a slide deck, but you'll be able to use the projector if you have a code sample or something else to share. While we'll ask you if you'd like to participate when signing up, this is just to gauge interest, and you can change your mind on the day of the event.

20:30 〜 21:30 Open Networking

Discuss the presentations or anything else Ruby related with the other attendees.
