They probably don't even pay attention to revisions. There isn't a certain one used in tournaments, not that I've heard of. The only times I've seen that done is with Capcom fighters and tournaments in Japan specifically using Japan region roms. Sometimes when I send board sellers questions about them they think I'm crazy for caring. I recall one guy responding with "wow I've never met anyone before who collects revisions before". Some people don't even know they exist.
The funny thing about the early Nintendo games is last I checked Twin Galaxies would only accept hiscores from boards with Nintendo rom labels. But they didn't cover the windows. So you wouldn't even have to peel them off and replace them to cheat. You could hack the roms and reprogram them with the stickers not having to move at all. Anyway I highly doubt they stick to one. It's probably possible to get in touch with one of them directly to ask though. Maybe they are on twitter or something.
