Something a lot of people are missing is that his first 1 million point score was in the top 99th percentile for RNG on points from barrel smashes. I think someone in the TG thread said the current record is only in like the top 70th percentile or something. Apparently his play style for scoring points was completely different than the current method of scoring over a million points. He completely relied on RNG barrels. That fact along with the fact it was proven he used MAME is highly suggestive he used save states, input recording, and playback features that are in MAME.

There is no doubt in my mind he outright cheated. There would have been no reason for him to use mame unless he was going all out to cheat using features only MAME would provide him.
