I need someone who knows a lot about Wikipedia's policies.

On Wikipedia's Tatsunoko vs. Capcom page, it mentioned a beta technique called "Assault". That's fine, except that it didn't mention that it was a beta technique. I changed the article to make it say that it was a beta technique, but it keeps getting reverted because it's "original research". The two sources for the technique are both using the same outdated press release that was released before the game came out, but they would rather believe the outdated sources than some random guy.

How can I make them stop reverting my edits? I really don't care if it mentions the "Assault" technique or not, as long as it doesn't say that it's a technique in the released version of the game.

Get a viable source, nitwit.
