I've read the rules for this game, considering getting into running the game after I've beaten it on a casual replay, but I only have the game on the Wii U's Virtual Console. Is there any rules against it or is it just like the current rules for emulators?

As i'm not a mod, i can't tell you nothing about that. But as WiiUVC is an official emu, i think there is no problem. Also, if you have any question there is discord of the pokemon series and we talk about this game in #side-games, so feel free to ask any question and suggesting changes to the route (this last thing is a little bit hard to be real). As a recommendation, just spam Pachirisu as much as you can.

Thanks for the heads up. I'll look into it.

Edit: Mind shooting me a link to said Discord?
