Need classic game sound effects for a project

hey guys, any of you know where I can get some sound effects from classic games? Things I'm looking for incude:

The mario theme from Donkey Kong when he gets the hammer

The "woca-woca" from Pac-man, and of course Pac-man dying

The opening Pca-man theme song

Defender sound effects

The dig dug music

and "retro" sounding explosions, say perhaps from missile command, front line, 1942, etc.

Thanks

 

It's called MAME, my friend. Look into it.
