The only way to get the razor claw is by getting all the stickers of the dept store and getting to the Evolution stones floor with Episode 13's help as far as I know...
Can someone share a download link of this previous episode?
Thanks a lot!
Rename the file that you want to play to Game.rxdata and delete/move/rename the one that is currently named like that.
They are ordered from oldest to newest I think, anyway, the time and day are there.
