This is from Crunchyroll. Quality is mediocre at best, but at least it’s subbed.
I hope someone who has more time and patience than me can remux these subs into higher quality raws, or maybe even those “Remastered” raws you can find at https://nyaa.si/view/1076859.
This batch contains episodes 81-131.
Now I need to wait for Crunchyroll to reach episode 189. Up to 160 is available and they really only seem to release a few episodes every few months...
I've also picked up the files to seed the multi-audio dub releases by DragsterPS, links are below.
If you want to watch the show in your local dub for nostalgia reasons, chances are you can find it there.

So what should I do next? Yu-Gi-Oh! Duel Monsters GX seems logical.
