As easy as importing a GBA game on the app, you can already experience what a real Game Boy Advance console owner feels. One functionality that some player seeks is the cheating feature, but sadly, free version owners have limited access to it.

To enjoy the full functionalities of My Boy, you must pay a small price for the app. Is it worth paying the price? I’d say yes, and I definitely recommend getting the paid version. For a one-time price and unlimited use, it’s a good buy, especially if you’re a Pokemon GBA rom hack player.

My Boy Free Version – User’s Common Problem

One common problem every My Boy free users encounter is the “Buy full version” notification which appears when entering multiple lines of cheat codes. This message prevents users from accessing the premium features of My Boy.

Multiple lines of codes my boy free version

Free users are only limited to one line of code in a single cheat. Although some cheats have one line of code, you will more likely need to enter multiple liner codes in the future.

If purchasing the paid My Boy is not an option for you and no other choice but to stay with the free version, consider following this tutorial as this can surely help you activate almost any multiple-liner cheat codes on My Boy free version.

The Solution: Easy Trick For Adding Multiple-liner Cheat Codes on My Boy Free Version

This tutorial applies to almost any GBA game support GameShark codes. For this guide, we’ll be using the Pokemon FireRed game and assuming you will activate a Pokemon FireRed cheat. You can watch a video version of this tutorial on Youtube, click here.

Step 1: Open Myboy

Open My Boy Free application, tap on the menu icon, go to “Cheats” and tap “New Cheat” or the “+” icon to add a cheat.

Step 2: Choose your cheat

Find a multiple-liner cheat you wish to enable. Assuming you want to activate walk through walls with the code of 509197D3 542975F4 78DA95DF 44018CB4.

The walk through walls cheat is a two-liner cheat, the first line is 509197D3 542975F4, and the second line is 78DA95DF 44018CB4.

Step 3: Add the first line code

Press the back button to return to the Cheats list. Proceed to the next step.

Step 4: Add the second line code

  1. I have the MyBoy premium, and I cannot get the specific encounter, or walk through walls to function. I’ve tried a small handful of the others with mostly success. I tried the master code, didn’t help. I don’t know my version, nor how to find out. Advice? Thanks ๐Ÿ™‚

  2. It does not work for me. I did the exact same thing but it still does not work for me. Why is that? Is it because of the other cheats I have?

    • Turn off all other enabled cheats or better remove them. Use one cheat at a time, enter each line of code as a separate cheat. This works most of the time.

  3. Hello so I have a problem the walk through walls don’t work and I have the rock tomb but I can’t use it I can use it for fights but not for smashing rocks on my way

  4. How do you get fire red v1.0 on phone because I really want tytar or tyranitar and I’m gonna reset all my progress uggh the worst thing just resting your days of progress

  5. Everytime i try to do this my app crashes and freezes and it always happens when i activate the first part and not the second i dont what to do please help me if you can

    • Probably it’s your rom version causing the issue and not the emulator itself? Cheats works best with MyBoy especially the premium version.

  6. what other cheats are there for My Old boy! free v1.5.2 because this cheat dident work plz tell me other like rare candy and masterballs and shiny encounters and legendary encounters plz

    • Hey there Ron, sorry but this method applies only for MyBoy GBA emulator free version and not for My Old Boy GBC emulator.

  7. Im trying to use the all encounters are shiny, or the one where every encounter is the pokemon I want to catch, and I do each line on a new cheat but nothing ever happens. Ive tried messing around with it, re watching the videos and checking through but I must be doing something wrong and I just cant figure it out

    • You did it correctly, the problem you are facing is probably the game doesn’t have the sprite for the Pokemon you choose.
