Converting 64kb to 128kb [3rd gen]

[filippos]

Hi everyone

I actually have a 64kb Emerald .sav file (Italian language, no cheat and almost full pokedex) that I wanted to export in 128kb so that I could beat the Elite Four without having to restart anything.

Already tried to change save settings / use other emus. I also tried to manually edit the .SAV file to make it 128kb without success, also tried to manually export the first 56kb (following what's written here) but couldn't make it work.

I'm pretty sure that the problem comes from the ROM I used, I tried but couldn't produce/run any 128kb save with that.

I already have another one that works properly with 128kb, but wanted to inject at least my boxes into a proper 128kb savegame, so that I could beat the Elite 4 and eventually use some tools (tried plenty but none seems to work with 64kb saves) to repair pokemon IDs.

Any hint or suggestion? I thought about making a tool myself, as I can code decently, but not sure if I have the time/patience right now.

Thank you

Forgot to come here and update post. Managed to fix it by doing the following

1) Save in game and make a copy of YourEmeraldGame.SAV

2) Without closing the game, save once again

3) Open the last SAV file with a text editor (Notepad++ will be fine)

4) Delete everything from line 3585 (don't touch lines 1 - 3584)

5) From the previous SAV, copy lines 1 to 3584 and paste them in the current SAV. They should now be lines 3585 to 7168.

6) Now, you have to make the file to the size of 128KB, filling if with "all zero lines". Exactly, you'll need to have 8192 lines, so 1024 more.

7) Now you can use this as a legit 128kb. Make sure to make a copy it before overwriting it with your 64kb ROM.

I think you can mark as solved. Thanks
