Might try snagging an emulator. Don't know of any classic NES game collections that were made legally available on PC or PS.

Also last time I checked Suprnova.org they had a N64 emulator and some roms on there. I downloaded Ridge Racer and Conker's Bad Fur Day a couple days ago. I think they had Zelda on there too.
