A while ago, I found my old exclusive NGC at E3 video tape from many moons ago (you had to call a premium rate number to get the tape!), and so I thought I'd upload it for all the rest of the NGC fans (from back in the day). It's not amazing quality, but I captured it from a really old VHS tape on a lower quality capture card to what I have now.
Enjoy!

If I can find the N64 Magazine Issue 1 tape lying around (I still have it somewhere), I'll also capture that and stick it online.
