Fusion364 Issues!!

I'm a noob to the entire emulator deal and I have a game that I really loved to play when I was younger for the SegaCD......
I have downloaded the Kega Emulator and unzipped it......
I have also downloaded a game for the emulator named Dark Wizard and unzipped it.....
When I go to the "Load SegaCD Image" option and select the Dark Wizard ISO File it pops up a window saying "Please Configure USA BIOS in Options-> Set Config-> Sega CD"
Does anyone know what I have to do in order to play the game???
I have tried almost everything and can't figure it out, so if anyone can help me, I would be grateful!!!

You'll need to download a USA Sega CD BIOS and configure your emulator to look in the folder you extract it to.

Edit:

Have a look on EP's main site for the BIOS file.

Ok, I downloaded [BIOS] Sega CD Model 2 (USA) (v2.11) and unzipped it.....
When I go into the Configuration Tab of my emulator and browse for the BIOS I just downloaded it doesn't display anything in the folder to select.......
WTF, why is this so hard to do? I'm at a loss.....

Sega CD BIOS files need to have .bin extension or the emulator won't let you pick them.
Problem is that some people decided to change ROM file extensions in Genesis romsets to .md or .gen
They are exactly the same files though, just change their extension to .bin
