I don't know if this is the right place to ask but since googling isn't helping i figured i'd try

I'm toying around with trying some nuzlocke runs of HG for fun and i have a couple questions

I'm running on >desmume and if i get pokemon like onix, haunter etc, is there a way for me to get around not being able to trade them to evolve them? And would this break the rules of the run?

also does each route count as a new area for pokemon to be caught in? So say i'm on route 30, catch something , turn the corner to route 31, i can catch something new?
