    Bad EGG Removal in GBA​



    A "Bad EGG" is like a computer virus. If a Bad EGG ends up being a hatchable one, it will most likely corrupt your game if you try doing so. It can even corrupt your game just by simply having it in your party. I once had a Bad EGG that corruted my file just from opening it's summary page.

    A "Bad EGG" can also be the direct cause to a certain bug, or any unexplained things happening in a game. Also, when I test certain games using cheat codes, I often intentionally make a "Bad EGG" just to try to sniff then snuff out a certain problem in the game.

    The Only way to get rid of Bad EGG's in GBA ROM's is by using cheat codes.


    - There are also other "ways" to manupulate cheats for Bad EGG removal.

    - But, the Safest and Most Reliable way is by using the method below.

    * Fire Red Tutorial (w/ Leaf Green alternative)

    * Ruby Tutorial-
    In Progress, still on the hunt for inject code safe and worthy enough of full testing. Plus need to add Sapphire (M) alternative to post formatting.

    * Emerald Tutorial

    Bad EGG Removal in Fire Red (w/ LG Alternative)

    How to Get Rid of Bad EGG
    in Fire Red    ​


    Hello There! ... I'm Amy. :)

    I'm here to provide a step by step tutorial on how to remove that Bad EGG in your poke PC, in Fire Red (USA).

    ... and alternative Leaf Green (USA) ROM base.


    Before proceeding with Bad EGG removal, make sure your character is located in town with a PokeCenter attached to a walking route number.

    ----------------------------------------------​

    *** IMPORTANT ***

    If you're playing Fire Red base with
    *Any Johto Mapping Involved*    ​

    Ecruteak City... is a "Glitched City". As a safety precaution, *Don't* do Bad EGG Removal in this area at all.
    ----------------------------------------------​

    Pease keep in mind, the only Safe and Easy way to get rid of Bad EGG's in GBA ROM's is by using cheat codes, of this nature.
    Before using such codes, make sure they're compatible with the ROM base you're playing and NOT used in any random order. You can REALLY screw up your game for it!

    I also recommend (if able) to create a back up of your current hard save file (usually .sav) and put elsewhere, best as a compressed zip file... just in case.


    I'll provide everything you need for doing this in Fire Red USA ROM base.


    *For Bad EGG removal in *Leaf Green USA* ROM base, use "Leaf Green Alternative" in spoiler.



    Please Take Extreme Care Reading Instructions Before and After inputting Any codes!



    You Will Need:
    .... I recommend using copy/paste function (if possible) to ensure codes are exact.

    Cheat Type- GameShark v3 (Action Replay)


    ~ 1 junk Pokemon to sacrifice (optional)
    * If this is your first time, I Highly Recommend You Doing This. In any case though, I Still Recommend you doing this. It doesn't only ensure you do the process right, it also makes it so you can keep that Mew and it's guaranteed safe for gameplay aswell (with appropriate badge to level). My tutorial will be using this option. But if you don't want it, that Mew is also completely safe to release once process is finished.


    Instructions:


    1) Place Bad EGG in Box 1 Slot 1 and junk Pokemon in Box 1 Slot 3... with the rest of Box 1 empty.

    2) Exit PokeCenter: Input "Master Code (M)" in emulator cheats menu. Make sure it's enabled.

    3) Exit town: Input "4.1 DMA Disable" code in emulator cheats menu. Make sure it's enabled.

    4) Return to town with Both codes enabled and return to PokeCenter.

    5) While inside PokeCenter with 2 previous codes still enabled, stand in front of PC: Input "151- Mew in Box 1 Slot 1" code in emulator cheats menu. Make sure it's enabled.

    6) Access PC with All 3 codes enabled then select "Move Pokemon" from PC menu options.

    7) Move Mew in Slot 1 and switch it with junk Pokemon in Slot 3.

    8) Scroll junk Pokemon to Slot 1 and switch it with "Invisible Mew" (in slot 1).

    9) Release "Invisible Mew" then access slot 1 junk Pokemon's menu *Without* selecting anything.

    NOTE: If you're scratching your head right now, because you see the junk Pokemon in Slot 1 (with open menu) but PC says that's a Mew... Don't worry, that's means you're doing it right! :D

    10) At this point, open emulator cheats menu then Disable codes in the following order: Mew, DMA, M

    11) Release junk pokemon.

    12) Close PC then exit and re enter PokeCenter.

    13) Access PC and select "Move Pokemon" from PC menu options, then scroll through PC Boxes *both* Forwards & Backwards.

    * If you did this right, all that should be remaining in Box 1 now is Mew in Slot 3.

    * At this point, if you decide you don't want Mew then release.

    Bad EGG Removal in Emerald

    How to Get Rid of Bad EGG
    in Emerald    ​


    Hello There! ... I'm Amy. :)

    I'm here to provide a step by step tutorial on how to remove that Bad EGG in your poke PC, in Emerald (USA).

    Before proceeding with Bad EGG removal, make sure your character is located in town with a PokeCenter attached to a walking route number.

    NOTE: If you have previously done "Bad EGG Removal Process" using FR/LG base in the past, the procedure for *Emerald ROM* base is a bit different.
    ~Keep That in Mind.

    NOTE:
    .. In Emerald base ROM's:
    As a precaution to prevent "soft-locking" game, you can't release last poke knowing either Surf or Fly.
    .. If Surfing Pikachu will be *Only* poke knowing HM-Surf... Please keep this in mind.

    *To Recap-
    .. This Pikachu is guaranteed safe for game play with appropriate badge to level.
    .. But if you don't want it, plus have another Surf poke... This Pikachu is also completely safe to release once process is finished.


    -Also... if you're observant, like Myself:
    You may be saying atm "Wtf, this chick giving me an inject for an Emerald (US) illegal surfing pika!"

    -Answer:
    ....... Yes, I realize it's "Technically Illegal".
    ........ But, you're most likely playing a rom hack or emu rom anyway.
    ......... It's Epic!!!
    .......... So Just Deal With It. :P



    Instructions:


    1) Place Bad EGG in Box 1 Slot 1... with the rest of Box 1 empty.

    2) Exit PokeCenter: Input "Master Code (M)" in emulator cheats menu. Make sure it's enabled.

    3) Exit town: Input "Anti-DMA" code in emulator cheats menu. Make sure it's enabled.

    4) Return to town with Both codes enabled and return to PokeCenter.

    5) While inside PokeCenter with 2 previous codes still enabled, stand in front of PC: Input "Shiny Surfing Pikachu" code in emulator cheats menu. Make sure it's enabled.

    6) Access PC with All 3 codes enabled then select "Move Pokemon" from PC menu options.

    7) Move Pikachu in Slot 1 and place it in *Slot 3*.

    8) Scroll to Slot 1 with "Invisible Pikachu" (in slot 1)... then Access It's Menu *Without* selecting anything.

    NOTE: If you *Still See Absolutely Nothing* in Slot 1, but Still has opened menu, plus PC say that's a Pikachu... Don't worry, that means you're doing it Right! :D

    9) At this point, open emulator cheats menu then Disable codes in the following order: Pika, DMA, M

    10) Release "Invisible Pikachu".

    11) Close PC then exit and re enter PokeCenter.

    12) Access PC and select "Move Pokemon" from PC menu options, then scroll through PC Boxes *both* Forwards & Backwards.

    * If you did this right, all that should be remaining in Box 1 now is Pikachu in Slot 3.

    * At this point, if you don't want Pikachu plus have a Pokemon with Surf.. Then Release.

    When I know data decryption, I usually do it before play a new hack... except Decomp FireRed and CFRU hack, they already did decryption haha! (Anyway I have no idea why Decomp Emerald hack don't do decryption)
    What causes Bag Egg? Data modified, checksum don't match. But with data decryption, checksum is no longer be checked, so no more Bad Egg haha!
