Yes, use google.
For example, to check the Twin Galaxies report here:
https://www.twingalaxies.com/feed_d...s-donkey-kong-and-all-other-records-removed/4
I keep hearing how he used save states, or tampered with the footage to include gameplay from more than one session, to achieve his score, among other things.
People should read the report that resulted in his banning, so see what the actual "cheating" was.
He submitted footage that, according to Twin Galaxies findings, wasn't generated in unmodified hardware.
There's a high chance the footage was from a machine running MAME, but that wasn't proven, because that wasn't part of the scope of the inquiry.
Since that leaderboard was for games done on unmodified hardware, and their conclusion was that the machine he used wasn't one, his scores were removed.
There were no claims of the use of save states, nor image tampering. I don't think anyone even accused him of doing so.
What the image showed, is that board transitions on MAME are rendered differently than on an unmodified arcade, and the ones on his footage closely resemble the ones from MAME.
Nothing on the footage he submitted shows him using any kind of advantage, or nothing out of the ordinary in terms of gameplay, outside of what I mentioned above.
He is guilty of playing (knowingly or not) on a machine that wasn't an original cab, or unmodified hardware.
Nothing more.
As usual, all people take from these reports is the word "cheat", and come up with all kinds of ridiculous allegations that aren't part of the actual report that resulted in his punishment.
