Nothing burger. Rule about joystick wasnt in place until 2009.
Then you didn't pay attention to (or watch) the video. The key point in BM's lawsuits, including SWORN statements by the corrupt individuals lying on his behalf, is that the machine was 100% original and unmodified in any way. That's where the checkmate comes in. Rules about modifications don't even enter into the picture (no pun intended) specifically because of the wording in his lawsuits.
Idiot.
If that's all you've got, it speaks to the kind of person you are.
It says a lot about what you know about submitting high level scores and what is meant by 'original hardware'. There are very very very few machines that would meet the strict definition of 'original hardware'. What is generally accepted is the PCB is unaltered, running original unmodified software. There are incidents, especially under the new regime where even modified software has been allowed, think Mappy and Asteroids for example.
Like I said, nothing burger, extra nothing.
At
https://drive.google.com/file/d/1BMbW-_fSwCFQ1Kzl59pj7TnoQiuAdgcJ/view there are numerous statements by people including Mitchell, and the "original hardware" point is made over and over and over again, including a statement by someone saying "I never by law or contract deal with anything other than authentic hardware from games or games manufacturers." (pg 38) Numerous statements are from people saying they are very familiar with the machines etc. The red joystick would not have been something these experts would have considered normal. Various statements say the same machine was used for both the 'Boomers' and the 'Mortgage Brokers' scores.
Mitchell also states under penalty of perjury that "I was in a very large room interacting with guests who numbered in the thousands. During the event, the gameplay was not only visible on the game screen but was also visible on a TV above the cabinet to give the guests greater viewing capability." (pg 52) From this statement you'd think he played in a huge auditorium with thousands watching him play below a big TV. It doesn't look like a big room and there's no such TV in the photoes. The photoes are significant as they do little to support Mitchell but throw doubts on the truthfulness of the various statements. There's NO known photoes of Mitchell with his score, or showing the supposed crowd etc. I understand that Mitchell has to pay for 9 or so of his witnesses to be questioned under oath (in the counter-case brought by TG, feel free to correct me if I'm wrong). The way I see it, Mitchell is holding a 6 high and is doubling down on his all-in bluff.
In any case the MAME evidence is damning - The new technical analysis adds to what is said at
