@TheEmeraldBlockTEB Ah. Well I can't help you much there. Here's a link to some old Newgrounds stuff collected over the years.

You could also message orbitz. His old account was tampered with, but he's been on the site for a long, long time.

Well here's a link to the history of the site. If you want to see what a lot of it looked like, let me know.

Well, thanks.
Despite not being exactly what I wanted but I could go for another read about NeoGeo's history, since it's interesting to read. I think I've read it few times and once fully reading for my interest about it's context.
Oh and how NewGrounds looked like, I've seen on WayBack Machine about it though haven't explored that much due to it's more persistent frozed state as an archive rather an interactive dynamic page with flash back then.
I hope I wasn't too aggressive by any means.
