3DSx Play Coin Setter
Allows Ninjhax users to modify the 3DS's play coin counter, in other words providing infinite play coins. Usage is self-explanatory, just choose the number of coins you want from the list, then exit using B. No more than 300 coins can be held at a time, this is a system limit.
You earn "Play Coins" by walking with your 3DS in your pocket. To combat abuse, Nintendo are imposing limits:
- Each 100 steps will earn you a single Play Coin.
- You can earn up to 10 Play Coins each day.
- You can only have 300 Play Coins on the 3DS at any time.
Nintendo have also said that the way Play Coins will be used will be left completely up to the individual developer.
For example, Lego Star Wars allows you to purchase special in-game content with them, while Street Fighter allows you to gamble them away in the hope of hitting the jackpot - Battle Figurines.
Mii Plaza and AR Games are said to use Play Coins also, but no details yet.
An option is also available to backup and restore the decrypted gamecoin.dat to the SD card, however this is not likely to be useful to anybody.
Note that this code is simply a modification of yellows8's 3DS HomeMenu extdata Tool 3DS, which contains within it code to modify arbitrary 3ds extdata.
