if im running on emulator is a mod that replaces marios model with waluigi allowed on the leaderboard? its obviously not a big deal to me if its not but i was just wondering

Is there a reason that emulator runs aren't just a seperate thing like the consoles? Is there just not enough people who would run to justify it? I have the Wii VC version, but I'm just curious as I can see why it would scare off runners who aren't well off financially.
