I had a few of the Pokemon VHS, most notably the Primeape one, which for a long time has been one of my favorite episodes of the anime.
I used to have the entire Orange Islands Saga on DvD, but I have no idea where it is anymore. I know I didn't get rid of it. I think it might be in an old box in storage.
As for the movies, I have 2000, 4Ever, Mewtwo Strikes Back, 2 Pokemon Heroes, 2 Pokemon Jirachi Wish Maker, Destiny Deoxys, Lucario and the Mystery of Mew and Pokemon Ranger: Temple of the Sea.
I also still have the original cards that came with the Heroes Movie and I think I have Jirachi Wishmaker card still.
