GCN Gamecube save converter

Seregon85 · Jul 3, 2017

I recently set up Dolphin on my computer, and quickly stumbled upon a problem. I had some ISOs from other regions than my save files on my gamecube memory card, thus I couldn't easily continue my old GC save games. I found an old app by PsyDonia called GCConvert that I managed to get working in the end, but it was a bit troublesome on my Windows 10-machine because of old DLLs. So I decided to do some research and try rewriting it. I have no idea if there was any wish for this in the first place, but there you go.

The app can be found on GitHub as well as attached to this post.

What the app does:
Takes your .gci save file (downloaded from Wii or other devices) from any region and converts it to the region of your preference.

Thanks! It is possible to upgrade it into a state it can manage the different formats used by Nintendont, Dios mios, dolphin, saves ripped using a wii manager
Sometimes they come in Raw, or a folder with the files, container of while card, I seen at least 3 types
I Had to use the dolphin and other tools to convert the different files

When I saw the title save Converter I thought it was a program to fix this

I'll look into it, could be an interesting next project.

thanks mate, just used it today, a year later lol!
the other converter that has been online is a pain to make it work (old dependencies)
your converted did the job in a few seconds

@migles You can easily add the GCI to a GC .RAW via Dolphin's GC Memcard editor.

i knew about it back then when i made that post 1 year ago.
however very likely was talking about the other formats that dolphin was not compatible with related to dios mios, there was a format that you needed a tool provided by crediar (i believe it was NMM to gci converter or something like that)
either way, since then i moved on to real carts, and dios mios project is pretty much abandoned\done so not much relevant anymore

@migles There's still Devolution and Nintendont.

Hey, yall still here? It didn't work for me. I converted the gci file for Sunshine from PAL to NTSC-U, loaded it onto usb with dolphin manager, and it still won't work for the NTSC version of the game. The icon for the save is still the PAL one also. However, the GC save manager tells me the file is ntsc. Help?

Same problem here! It changed the region correctly but it maybe has something to do with the savegame title?

I don't know, the first one is the converted one from the NTSC version in PAL the second one is the save file generated by Nintendont.

The converted save game was recognized in the gamecube Bios but not identified by the game as the correct one.

Tried editing the save file wtih an Hex editor to show the same data as the generated PAL save at the begining of the file(Name and code of the game). It's now detected by the game but as a corrupted save file.

Thanks for this, it worked for most of my games.
Some US titles use game ID in format "XXXE8P" instead of "XXXE01", example F-Zero GX and Spyro: A Hero's Tail. Some games use other weird game IDs. The tool will not work for those but with manual hex editing I was still able to convert them.
Sonic Heroes also used a different game ID, but I wasn't able to convert that one even with manual hex editing, it will just error on trying to load the save, so there must be regional differences in the save file itself.
Same with Mario Party 7, it complains the save is corrupted after converting, and wipes the save.
Not sure what to do about these two.
Mario Party 6 also complained the save was corrupted but it was able to repair the save and it seems to still be intact.
So out of 15 games I converted saves for, 10 of them converted without issues. 3 of them used a weird game ID that the tool didn't handle (maybe this could be solved by using GameTDB to check what the actual game ID for each region should be). 2 of them absolutely would not successfully convert likely due to regional differences. And 1 of them complained about corrupted data, but was able to repair it.

Since someone revived it, I decided to give it a try on FFCC, but it doesn't work. I use Dolphin, I manually checked the game ID change, and the file name, I changed the file name and moved it to the EUR (PAL) memory card and it works, but none of my saves are actually there, They are empty, and no progress is made or characters created/ dungeons beaten or years past which sucks.

Works in Luigi's Mansion, but not in Star Fox Assault, Metal Gear Solid and Geist.
