I've read the rules, and it states that run-ahead isn't allowed if using Retroarch, but cannot see any mention of whether this is allowed for other emulators or not (perhaps I missed it).

Mesen has a run-ahead feature, if I set it to 2 frames it distorts the audio, but with 1 frame it seems ok. The input lag is honestly pretty bad, so I wondered if using this setting would be acceptable or not?

Thanks!

Why the fuck is Nescard still a mod in here, nobody likes him, and he doesn't approve legit runs from experience , maybe cuz he's too busy or doesn't care, but it's a thing, get somebody else in here and perhaps on other nes games too.

Burritodad, this isn't a Nescard issue but a moderator issue in general, none of the mods here are even remotely in the Tetris scene or any discord servers, Nescard left all discords years ago and the others have yet to send a single message to the community at large from what I've seen. This type of ignorance of what the scene is doing just leads to a terrible board, legit runs being denied and a dying scene where none of the top players have submitted times in years
