I got the game Mario and Sonic at the Sochi 2014 Winter Olympics. I really like the game but unfortunately it doesn't work anymore. Every time I insert the disc it says: invalid disc. This game is no longer offered in the Nintendo eShop and on websites such as Amazon, etc. You can get it either used or new from a price of over 100 euro. Do you know where I can get the game at a reasonable price or how to fix the invalid disc error? I haven't played the game in a while and suddenly it's no longer legible.
Buy it used…
Even then, although the game is about 6 years old and you could buy it for about 50 euro at the time, it sells for 70 euro or more.
