Good thread but this episode had some filler in it, Boruto not wanting to cheat to win give me a break. He always looked for short cuts(until after Momo event) yet he refused to cheat and threw in the towel.
You are misunderstanding Boruto's character and essentially defining it solely on that one all-time low point of his (the chunin exams).
Boruto cheated in the chunin exams mainly to get Naruto's attention. I'm not saying that this was a good or justifiable reason to cheat, but that was his reason nonetheless. He doesn't look for a way to cheat in every facet of life as you seem to believe he does. As for the videogames, (as a gamer myself, I know this), the use of cheat codes in casual settings (as opposed to competitive settings like tournaments) is not looked so down upon as cheating on things like exams. In fact, you can even buy things like action replays (cheat code devices) at mainstream video game stores.
Boruto was not trying to impress Naruto or anything like that in that game of shinobi bout. He had no reason to cheat.
Now you'd be right in saying that Boruto looks for easy ways out and is to some degree lazy. However, Boruto's general laziness is generally still legal in whatever facet or activity he is acting it. The cheating, as I said before, was a one time thing mainly to get to Naruto.
One more thing:
Who cares whether or not an episode is filler? Why would they care? Kishi isn't a deity and neither are Kodashi and Ikemoto.
