I used Genymotion to do all my rerolling. Since this is based on personal experience, I can't tell you how this works on Andyroid or Bluestacks, but maybe another member can enlighten all of us. :)
Note: According to a friend, Bluestacks doesn't work, as it hangs on the Sega screen.
Before you start, make sure you enable "download from unknown sources" under settings and security.
1. Search and download genymotion (too scared to provide download links until I make sure it's okay. Use google!)
2. Complete the Oracle VM setup first.
3. Launch Genymotion (Genymotion Shell is the cmd box--not the one you want).
4. Create the virtual machine (VM) that you want to emulate. My suggestion is to use version 4.3 (use the dropdown box). The device model doesn't seem to matter (I used the Nexus and Galaxy S3).
5. Go find the download links for the "ARM translation" and "Google Apps." The correct page should provide the instructions on how to properly install the software. Do it.
