Help identify this game

At the recent Northwest Pinball and Arcade show, there was a Raiden Fighters 2 cabinet that wasn't RF2, but was instead this game. Since games were all on free play (or pumped full of credits), the title screen never showed.

What game is this?

That's Daioh.

Cool! Thanks!

Now that's a helpful original post for identifying a game.
