Hi, I noticed this game currently only has the NES version of the game for the leaderboards but I was wondering if the Gameboy Color version would be accepted or added, I realize it would probably be slower because you couldn't use the Any% JP route since there would be no second controller but I thought it would be interesting for an alternative GBC route especially if it ended up being a significantly different version.

It is a significantly different version, actually. While it looks similar, it plays completely differently, and while it doesn't have any of the NES version glitches, it does have it own set.

As an aside, I'm the only one I know of that's actually tried to run that version, and I never got any runs that I was actually happy with, and I prefer to at least have one run up if we're going to create a board for it.
