Shining Force CD Problem

I made a CD from the ISO and MP3's and when I booted the CD with Gens, it said that the backup RAM cartridge is not initalized. How do I initialize it or what do I do?
Here's what ya do. When you boot up the game, press either the a, b, or c button when sega's spinning logo pops up. then go to options and format both the internal and external ram's (eternal just to be safe). once you've done that just click on the cd-rom button on the main console and it should work fine!
