?????

Its Medabot in the West and MedaRot in Japan.

Can a game db admin clarify why its written Medalot?

Med a lot

vgchart and gamewise are one of the few that call this game Medalot, I wanted to know why?

The maker of the games writes it "Medarot" apparently.
As seen in the URL:
http://www.medarotsha.jp/meda7/

Indeed, so why is it Medalot here?

Well, because if you want you can transcribe the Japanese into Medalot, too. There's no rule whether to use "lo" or "ro", in Japanese it's the same.
And transcribed titles in Western databases are often false. It's nothing new.

It seems out of place when everyone is reporting Medarot, that you decide to be the 1% that reports it differently. It creates confusion.

That's how the internet works. :P

And there's no chance you can correct it.
One time I tried to correct a few titles in a big database (I think gamespot or some other big site... don't remember). I even sent them emails. They wrote back that they'll leave the titles as they are (even if they're wrong), because other sites have the same titles. :/

This guy?
