Thanks to everyone for an unforgettable RU 64!
Once again, we've done it. RU 64 was a huge success, and that's thanks to you: exhibitors, visitors, collaborators, and everyone who keeps the MSX spirit alive.
We want to give a huge THANK YOU to everyone who participated and helped make this edition a success:
To Retroscroll, who made us have a blast: we are grown-ups, but we felt like kids once again in the arcade area.
To Conexión MSX who once again worked hard on the conference area, with delightful talks for every fan of the computer.
To all the exhibitors, for bringing us hardware, software, memories, good vibes, and a wealth of retro passion.
And of course, to all the attendees, who are the true soul of every RU.
If you were there, we hope you had as much fun as we did. And if you didn't, don't worry: we're already thinking about the next RU, where we'll meet again, share news, and continue celebrating our shared passion.
In the meantime, don't miss this year's recap video. Hit play and relive the best moments.
See you at the next RU!
