For the most part the top of the leaderboard has console runners, but there are some that have 1:24ed while on emulator, and Eriror specifically did it on Retroarch with an Ibuffalo USB controller if memory serves. And Skipsy nailed it, G3rdo posted a great time while also playing on Keyboard. The rules for what is proper to play on has been pretty static, at least since I started playing 2.5 years ago. I believe someone has also posted in the discord for good retroarch setups to make it pretty painless. Good luck on the grind!
