I've used Pokemon Fire Red 1636 and it does not work. I tried searching for a Pokemon Fire Red 1635 ROM, but I haven't found one yet. When I do find the ROM that is needed to be played I'll tell what type you would need, but you have to do the searching. I think 1638 might have been the one also. I have played through Amythest Sewers before and not encountered a level 49 Weezing, and I do not want to. Coincidentally in Pokemon Black 2 and White 2 there is a sewer line before the third gym and the gym leader is Poison typed and female like Roxie and there hasn't been a Poison gym in a while.
