Hello, Im looking for someone who can help me to mod pokémon masters EX game for Android. I dont understand about android programming so I need the help of anyone who can do this. This game is a gacha game so I have found a few people who can "inject" Items and pokemon from the gacha and I dont know if someone can be able to do this for me, explaining me the process so I can do that to. Thank you in advance
