Question: Can Roms downloaded from Myrient be used in Dolphin?

Hi, I'm a newbie in emulating games, and I'm sorry if this is supposed to be common knowledge. But I'm setting up the Dolphin emulator, and I understand there are certain file types for roms it does support, and certain ones that it doesn't. I have a few RVZ's, which I'm sure will work, but when searching on Myrient's site, I saw that every file was a Zip, which Dolphin can't directly emulate. Is there a way I can convert the files at all, or will I have to search somewhere else? Thanks in advance.
