Help is needed!!!

Hello to everybody 'ere!
Actually, I need a help that concerns my ChankastAlpha 0.25 emulator. I couldn't find dc_flash.bin and dc_bios.bin in order to enable the run mode of the emulator and to strart my Sonic Adventure2 game! Is anybody able to help my in this special case?
Any help is highly appreciated!
Thanx a lot in advance!

Sorry, we can't help you with this because BIOS requests are not allowed here. All I can say is that you must use Google or P2P for stuff like this. No further info.
