I'd also recommend Toonami Aftermath. It has a bunch of shows from the mid 90s to the mid 00s. The Saturday morning line up is really great.

You can also get it running in Plex (requires Plex pass) with these two projects:

This looks amazing but i dont see how to watch it. Perhaps because in on mobile? I see a schedule with what’s currently airing but no video.
I linked directly to the schedule. Go to the home page to see the video.
