in 2020 I did a Tekken Advance speedrun on a mobile emulator, which was accepted, but then I found out that mobile emulators are not allowed, I would like the speedrun to be deleted so that there are no injustices, how can I do that?

go to your run on here, click the three dots and select delete run

Also, tell the moderators to ban emulators in their game's settings, if they haven't already
