Yea I thought it was common knowledge that he used emulator. Now he is trying to act like he didn't. I thought there was video evidence like you said in last post that showed not playing on true arcade cabinet.

I was actually watching a video on it. The thing is that one of the major figures at Twin galaxies who was in charge of verifying records was found to have cheated (he got a score on a game that was literally impossible even with perfect frame by frame TAS). So that's when they started looking into these things a bit more closely. It's literally a slight little gap that appears between some of the steel beams. It would be nearly impossible to notice unless you were really examining the whole thing closely.
