got a couple questions ... is there a discord server for cliffhanger, and i got a nestopia emulater and dont know if they are allowed or not because i dont wanna waste time practising and then find out that it is not allowed and are mods active aswell because its a pretty lonely game to speedrun.

There are other EMU runs on the leaderboard, so they are accepted, and Nestopia is one of the emulators that are generally used along with FCEUX and Bizhawk
