To use the emulator you need to have the bios files. If these are no included you can download these and add bios files in the same map as the emulator's executable file is.
If the download won't unlock, Tweet, Like, Google+1 ect.. then try to download again.
Step 1: Download the BIOS Setup above.
Step 2: Make sure the install path is the same as the emulator
Step 3: Open the emulator, it will not detect the BIOS.
Step 4: Done!
