I feel like without proper video proof requirements, enforcing this would be pretty hard. However, if we know that the player uses emu beforehand, we could freeze someone's profile upon them achieving a top 100 time and only unfreeze once they provide proof of them switching over. This way their times are still on the site, but they can't submit more times. Seems like a hassle, but I can't think of other ways that we could enforce it other than having the emu players self-moderate themselves and simply not submit their times. Another possibility would be if there was an option on the site to filter out emulator times by default. In that case we wouldn't need the top 100 emu rule and just say that if you want your times to be compared to everyone else's you'd have to switch over to console. Not possible at the moment, but could potentially be used in the future if MKR happens or if the site gets an update.

There's no way of knowing if someone is using save states for FLAP attempts.
