Anime or Manga,
Anime is probably the only thing you'll find, (since I've never even knew there was a manga for it untill recently).
Preferably (for anime), the end of Gaurdian Force (the final 4 episodes) and Century 0. (what the hey, Fuzors too, since I never got to see most of that one)
I would request the new Genesis, but I dont think that's been subbed yet.
NOTE: Please don't tell me P2P, because I tried Limewire already and only got crappy ~36mb wmvs (pretty grainy).
