ROM Hack Is it possible to edit GBA VC Pokemon saves?

[jacobas92]

Searched for a few hours and couldn't really find anything on converting saves or editing them. Is it even possible? I know I'm a dirty rotten cheater, I just want to play around with my fire red save.

Sorry if this is in the wrong section, I honestly had no idea where to post this.

First of all, you have to extract the save file from the .CIA, and I tried SaveDataFiler, JKSaveManager, Homebrew Save Manager and SVDT, none worked. If you managed to do that then I think a gen3 save editor like "A-Save" will do.

Thanks, I know there's something going on with the save file cause iirc it's like 192kb and I thought the max size was 128.

That's because it's Encrypted, someone needs to make a GBA VC save Decrypter.

It dosent work in emuNAND only in sysNAND HOMEBREW MENU.
How to chose files it only shows:
[Save Dump]
========================
A: Chose
SELECT: Unmount SD
START: Reboot

and it gives me a agb_dump.sav, how does it work?

If you're worried about emuNAND vs sysNAND just dump and reinject partitions using Decrypt9, and about the homebrew menu it's perfectly possible to run it as an A9LH payload (I'm assuming at this point pretty much everyone has it, unfortunately)

I know, but how to browse and chose the cia from you want to dump the save file?

Yes.

I did dump the save but it dumps it in 64k, how to change to 128k?
Okay, PokeCrafter 1.4 can handle 64k saves.

 

[jacobas92]

Awesome, it worked. Thanks! I didn't even know about PokeCrafter.

If you want to use the 64k save dump in Visual Boy Advance (white screen) do this:

Open the desired ROM in a hex editor and find the following string:

Code:

D0 88 8D 83 42

Note: This string can be found in two different locations in some ROMs, make sur you find and edit both of them!

Also the strings can be found in two different lengths:

Code:

D0888D8342 [xx xx xx] 2410491068

Or

Code:

D0888D8342 [xx xx xx xx] 2410491068

Edit strictly what's between

Code:

D0888D8342 [and] 2410491068

Replace the xx by 00

Exemple:

For Ruby, Sapphire, Emerald check RTC in Options>Emulator, and don't forget to change the save type to 64k.
PS. Or just play with the ROM you used to make you're custom VC, cause it to had the same white screen bug.
