Recently I started rewatching the series from the very beginning, except subtitled, and after searching around and using different sites I managed to watch all of them up to episode 39 of the indigo league season. The problem I have now is that subtitles have essentially stopped existing for the rest of the episodes in the first season. So if there are any subbers reading this I am begging you to make them for me and the other people that prefer the japanese audio over the dub.
All three series before Best Wishes aren't completely translated. Only some random episodes are translated for the original series and half of Diamond and Pearl (last 100 episodes I think). Unless you understand Japanese, you're out of luck. It'll take a long while for the whole series to get completely translated, unless they only translate the important episodes and cut out filler episodes.
