Radio Rayless（レディオレイリス）is a cancelled futuristic racing game that was in development in 2002 by Now Production, planned to be published for GBA. The game was shown in a few Nintendo leaflets along with many others GameCube and GameBoy Advance titles, but this one seems to have vanished forever.
For now the only (tiny) screenshot available online for Radio Rayless was posted on Twitter by Akamid83:
I'm an Italian gamer with not enough free time to play as much as i'd like to and sadly not enough time to write about cancelled and beta games. Founder of Unseen64 in 2001, i'd like to sleep more than 5 hours a day, but i have to pay the bills. I'm currently working for various italian & international websites for a better User Experience & Search Engine Optimization, you can add me on Twitter, Last FM or contact me by email.
