This cheat is just like the Pokemon Modifier cheat where you just replace the last four or three digits of the cheat code.
Unli Masterball (in PC): 82025840 0001
Unli Rare Candies (in PC): 82025840 0044
Instructions How to use these codes (FireRed, My Boy - Android GBA Emulator [I got Full Version]):
~ ALL STEPS ARE IMPORTANT ~
Step 0) Turn off or delete any code on your Cheat Code List Step 1) Stand outside of a Pokemon Center Step 2) Save your game Step 3) Create your new cheat \Example\ Code Name: Rare Candy Code Type: CodeBreaker Code: 820258400044 When you save it, it should be already activated. (if you've already created the cheat code, just activate it) Step 4) Get inside the Pokemon Center Step 5) DEACTIVATE THE CHEAT CODE Step 6) Go to PC -> Item Storage Step 7) Withdraw ONLY 1 Rare Candy Step 8) Notice if the Rare Candies in storage is double, if not, that means it's successful. IF it is true, which means it has bugged, then close the game and redo all the steps above.
Step 10) Exit and go back to item storage again and withdraw as many as you want, BUT do not press the down button. Just pick numbers from 001 to 999.
It works nice for ~10 items.
Other items: (In case you do not wanna search for them)
Here you can see a video of the Rare Candy cheat in action. It's the same for the other items, just change the code as you need it for the different items.
