Part 1: Fix the save problem
(This is valid for all pokemon games, in every languages)

The first save problem is you can't save on a Pokémon game in CIA.
To resolve it, we need to hex edit the .gba rom.

Open the desired .gba in a hex editor (HxD is highly recommended) and find the following string:

Code:

D0 88 8D 83 42

Edit stricly what is between:

Code:

D0 88 8D 83 42 [AND] 24 10 49 10 68

Replace the XX by 00.
Note: You may find this value twice, so be sure to also do it twice in this case.

Exemple:


Now it's ok, you'll can save.

You will can save, but you will always see a message "Save data are corrupt, the last save will be loaded".
Even if the game save fine, even if this message is useless because all is fine, even if you can totally ignore it, this message is annoying, so we'll remove it.

Part 2: Remove the save data corrupt message
(This is only valid for Pokémon Ruby, Sapphire and Emerald, and only for english / french languages)

Open the desired .gba in a hex editor (HxD is highly recommended), use Ctrl+G (go to offset), then edit the value, by the other value here:

Code:

-> Ruby and Sapphire [US]
Offset 0098F6: Replace 2B by 3D
Offset 0099A4: Replace 1D by 65

-> Ruby and Sapphire [FR]
Offset 009AC2: Replace 2B by 3D
Offset 009B70: Replace E99B by 319C

-> Emerald [FR/US]
Offset 02F9CC: Replace 5D by B1
Offset 02F9A4: Replace 084802F037FA by 000000000000.

Save the .gba, turn it in .cia, install it, and enjoy.

@Asia81
jir just want to ask whats the difference between this fix and @AmeenX fix? thanks

 

"Pokémon"

Here These aught to help ease the crappy hex editing methods.
@Asia81 you asked for a pokemon mystery dungeon patch? @yafeee made one and I ported it to the USA version of the game.

 

so basically these patches can be used directly on "Unltimate GBA VC injector" without hex editing the rom?
with these, i will not experience any save issues? am i right? thanks

 

@Asia81

hello, i just need help here...
i used this method and everything works on RSE
but even though its also working on FRLG, theres still the annoying message "save file cant be loaded, previous save will be loaded".
is there any updates on finding the offset (Part 2 for FRLG) that should be modified to prevent these message?

and for the pokemon mystery dungeon, i cant manage to save the game, always tells me "save failed"
and after restarting the game, the game cant detect any save data... :-(

thanks...

 

Thanks for making these, applying them now. Though it doesn't seem like the Mystery Dungeon patch has anything in it? The EOF immediately follows the PATCH.
edit: also, a request: could you list the exact ROM names that these patches apply to? There seem to be several rips of these games in circulation, e.g. Leaf Green has to (U)(Independent) rips, one with serial 1637 and one with 1691.

 

Now I wish I had my 3DS XL working.

 

Still no fix? How sad.
