Hacking Convert Wii VC NES save to .sav

[Scotte 2.718]

Hello,
I have used FE100 to convert the save file on the Wii from the virtual console game, Legend of Zelda, to a .bin file. I have seen some stuff on converting the saves for other systems but not for the NES. Does anyone know how to convert the .bin file FE100 gave me to the emulator friendly .sav? I have tried just changing the extension and it does not work. I have attached the .bin file.
Thanks, Scott

you'd probably have to extract a certain portion of it with a hex editor,
since i'm guessing it also saves info for the VC emulator,
or maybe its more like a save state.

my first thought is to start a new game with he normal ROM and make a save file,
and make a new game with the VC ROM and make a save file,
and compare both to see if a portion of it matches,
that might be sav file portion,
get the right address points, extract and convert to .sav
idk, that's my guess

If you want to upload the file I can take a look at it and see if I can convert it.

Just grab the save file right from your Wii, and upload it, and I am pretty sure I can rip out the .sav for you.

It is possible.
Instructions right here, so that you don't have to reinvent the wheel.

I should point out that those instructions are quite old. I'm pretty sure that if you use the "extract save to emunand" feature of any recent backup loader to copy the save to your SD card, you can then simply browse to the folder where the save file is and copy the portion that corresponds to the native save file. In fact, you can probably just use savegamemanager_gx to copy the save file to SD card and grab your native save file from there. It would be the easiest.

Of course, this will only work for games with native save files, so you would be out of luck with the majority of NES games. Emulators use freeze files to enable saves on those games and no emulator will use the same freeze file format as the Wii.

Thanks, for the reply's guys. I was away, so I didn't get a chance to look at them till today. I guess my save file didn't upload right, I will try re-uploading it. Thanks for the suggestion themanual, I will try that later to day if I get a chance.

OK, managed to download your file now, and here you go.

Tested as working in FCEU GX Wii.

Thanks damysteryman, I really appreciate you converting it for me.
How were you able to convert it? Did you use FE100? I hate using virtual console, and I want to switch all my VC games to an emulator.

 

[damysteryman]

Well, I did not need to use FE100, since you already did that for me (I would have needed to do so otherwise though).
And the .bin inside of the unpacked Wii save pretty much was the ordinary .sav, but with an extra 0x40 byte header attached to the beginning of the file, which appears to be used by the VC title. So, just removed those first 0x40 bytes with a hex editor, and then loaded up the .sav in an emulator to test.
