N64 is the standard, they'd have to have their own leaderboard similar to the standard categories because lag and loading times would mean you'd have to use VC to get the fastest time, separated leaderboards arent worth.

It's already an obscure category, no need to make even more obscure subcategories. If you're gonna run mario at that level just use the platform everyone at that level already uses imo
