I don't know how the laws work, and honestly I don't know how cheating is dealt with in sports, as I don't follow any at all.
I would imagine some sort of fine? But that's kinda why people are thinking and wondering how far this will really go.
Fines are an interesting one, not least of all because many are voluntary after a fashion -- only the government and their sanctioned bodies* can levy ones you are compelled to pay, give or take contract law which is a different matter again.
*which can include some professional bodies but this gets very odd -- usually see it in medical and financial circles, technically you could not pay it but you would lose any accreditation that you have and thus may be walking away from a lot more, other times the professional body is a real government thing with actual powers.
One of the articles I skimmed for the last post actually covers some of the stuff involved
https://www.theguardian.com/sport/2017/feb/14/lance-armstrong-lawsuit-government-fraud
I don't really see a path for government fines here, there are no game playing professional bodies (see the earlier comment about everybody and their mother -- this is one of the problems with such a thing) and thus we are down to contract law and civil law with whatever sponsors or leagues the dude might have been involved in. As such contracts are extremely unlikely to be public at this point (if they are made public as part of a court case then that will likely be the only time we get to see such things) I have little to go on. Equally at this point as far as I am aware it is an internal investigation and that also plays into what might be able to be done, or what needs further investigation as laws on
private investigations in computing are complicated.
I also have to stress again this is not necessarily cheating, to use words common in the sorts of contracts mentioned then it might well be a "deceptive or dishonest practice", possibly also "unsportsmanlike" but that is a whole other can of worms. Cheating most likely requires an active component, not sure where to look for this but gambling laws vis a vis things like card counting are probably not the worst start.
A place to watch might be

Ha! I watched an update video a few weeks ago as to evidence of shadiness (even more than the VHS tape being counted despite the rules). I'm so glad he was dethroned and everyone now knows what a con he is.
@FAST6191 The original hardware bit isn't just nitpicking. There was shown to be timing issues in MAME that created an unfair advantage for him in at least one game he got a high score in.
While I don't disagree that inaccurate emulation could make for some interesting twists I suppose it is more that I have spent too long laughing at the nonsense that various speedrunning communities get up to and it is spilling over into this.
