How do I rip sounds from a genesis ROM?

[BlueSoD]

Title is mostly self explanatory. I'm trying to rip sound effects from a genesis game called Ristar. A page exists on the sounds resource but it only contains the vocal samples of the main character. I'm a complete newbie to sound ripping in any way, and the game lacks a sound test (Well, actually, it doesn't, but it's for music only). I've looked it up around the web but everything I found was either too complicated, for music and not sound effects, or just flat out didn't work. Can anyone give me a hand?
