Can´t run ikaruga

[gandalf]

I downloaded the Ikaruga , and i have the chankast and the DC_bios,i loaded de iso with daemon tools and i configure the emu to run from the "emulated" CD.
So...i run chanka, i press in start,the bios starts fine and then i need to configure the date......
I press play game (or similar) and the bios start over again!.
Whats happen here?

Corrupted flash file (dc_flash.bin). You should get that file again.
