Emulator runs are allowed for accessibility. Most emulators will play slower than an actual 90k PS2 with FDS, or on par. If an emulator is faster than actual console or too inaccurate, it should probably be banned. Playing on emulator actually makes you play at a disadvantage.

Despite being allowed for accessibility, top level runs should be done on console to preserve the legitimacy. It could've went the route of only allowing them over a certain time (let's say anything over 23m). But instead was set to follow the WR time.
