Is it possible to hack currency for this game, like RP, diamonds, dalcom/arena coins (even if you can only modify the reward RP you get for playing songs), OR the success or cost of card upgrades? The prices for stuff you can buy with RP/diamonds in this game and the success rates for grading up cards are getting more and more ridiculous, so I'd really like to know if there's any way to hack that. Thanks in advance.
