Testing recording with Ducktales on the original NES. If anyone asks, yes, that is my voice. Ignore the other voices in the background.

Do you have a capture card or anything like that to record console gameplay directly?
If not, and you're only recording old games, I would suggest using OpenBroadcast System and recording an emulation of the game on your computer. Works just as well, much better quality.
Mandatory Disclaimer: Emulation=illegal if you don't own the game.
Then add in the audio post recording. I've done videos for youtube using both methods.

Also be mindful of resolution. Watching NES footage stretched to 16:9 looks really gross.

Also on the issue of emulation: Here's the deal, the act of using an emulator is not illegal; if you dump your own rom files that's your business. It's obtaining ROMs from rom sites that is illegal, so as long you don't admit to 'stealing a rom off a site' nobody will really care either way.
