How do I transfer data from my old device to my new one (so I can play Pokémon insurgence in my new device with the same data). Please help me please 
You have to copy and paste your save from your old game onto a flashdrive to a new computer. I forgot the directory that the game is saved in but you can look that up through a few google searchs of “pokemon insurgence save location.” Finding a thread about that can also provide further info on how to transfer saves
Assuming you’re using windows:
Or if not:
Windows: C:\Users\(your name)\Saved Games\Pokemon Insurgence
Linux: ~/.wine/drive_c/users/(your name)/Saved Games/Pokemon Insurgence
Mac: Right click the app, Show Package Contents, drive_c, Program Files, Pokemon Insurgence
Mac (El Capitan&Sierra): Right click the app, Show Package Contents, drive_c/Users/Wineskin/Saved Games/Pokemon Insurgence
