About a month ago I helped my nephews finish the game on their Wii - they rarely get to play and I think they usually just replay what they know - and made sure to grab the Sapphire before doing it. Then I, the maverick, got somebody to take the money and I force-quit the game. Lo and behold, when I returned, the money was indeed back. I showed my nephews, told them exactly how to do it and showed them my force-quitting the game and how. So I can confirm from personal experience that it works.
Seemed all good, until later that day, I checked and the money was gone! Turns out one nephew (the greedy one, the selfish one, the inconsiderate one.... That weekend underlined these character traits in him, he was terrible about this stuff all weekend) had played Hex, got the money, dutifully restarted the game, got the money again, and forgot everything, and just decided to keep playing, without a reset. Game saved, money glitch gone. He just turned 9, he's old enough to understand and follow instructions in the form and repetition of what I gave him, with the importance I placed on it. *sigh*
But it was working!

I can confirm that!
Mantez: I suspect that people have posted videos of this before, I think I even looked one up when I first heard about this.
