Last two badges of my White Red Mono-Color, neither were any difficult. 200 more points.
I then beat the Elite Four this morning, then N and Ghetsis a little while ago. I believe that gets me the Mono-Color requirement?
It says "completed first adventure", not Hall of Fame. I hope I don't have to rematch the Elite Four and beat Alder, but if I don't (which I shouldn't have to considering N and Ghetsis are way harder than him anyway), that gets me 200 more points.
Finally, I got this from my Fire Red version that still has my Red Mono-Color save from my Ultimate, and got 9999 coins for Porygon.
