i searched a lot on torrent sites, streaming sites, and on the internet archive, but couldn't find it. Sorry
>if there is no other way though then i will pay 200 yen and scrape the episodes and upload them myself
you might have to. I can't really find them anywhere, i only found 30 episodes on streaming sites like 123anime, but i assume those are the ones from shittyroll you mentioned.

Thanks though, it looks fun. I'll watch the 1990 version ヽ(´ー｀)ノ
