Downloading "I'm a rookie"

Hey, I'm new to this whole thing about DL onto my PC. I want to play old sega games. I've read the forums, this info is foreign to me. My question is: When I download do or can I save it to my PC via C drive, folder or do I need a dvd to save it on?
Please help

That was a hard-to-understand post, but if you are refering to a SEGA Genesis game, then yes.

You can save old sega games and emulators anywhere you want to. If you're talking about Dreamcast games you'll need to look into virtual drives... It's hard to say what you can and can't do sense so many aspects of emulation are different... You need to be more specific. Feel PM me if you have any questions.

No offense, but if you have problems already with downloading it's best to take a PC course before even thinking about emulation.
