Hi.
I wrote a small python app that allows you to convert your SNES Virtual Console saves to .SRM format, and vice versa.

Convert your 3DS Save to .SRM:
1) Extract your save files using JKSM.
2) You will get many files in your save folder, but you'll only need the .VES file.
3) Open 3DS SNES Save Converter.
4) Select your .VES file.
5) Click on 'VES to SRM' button.
6) You'll get a .SRM file in the 3ds-snes-sc directory.


Convert your .SRM Save to .VES (3DS):
1) Open 3DS SNES Save Converter.
2) Select your .SRM file.
3) You will now need to write the Game Preset ID. You can get it from here.
Remember not to add 0x to the Game Preset ID.
For example, if you are converting a Super Mario World save, you should only write: 1011 (instead of 0x1011)
4) Click on 'SRM to VES' button.
5) You'll get a .VES file in the 3ds-snes-sc directory, rename it to the product code of the game.
For example, if you are converting an Earthbound save, you should name the file: KTR-UAEE.ves
6) Import your save (a folder with only the .VES file) using JKSM and you should see your progress when booting the game.


Release (Win)Source (Removed)

3ds-snes-sc was inspired and based on the following posts:

I'm not sure, but you could test and tell us if it works.
Just tested it with A Link to the Past on the Wii U VC, and it worked flawlessly!

EDIT: I also tested the tool with more games on the Wii U VC, and while some of them did work, others didn't.

Just wanted to say thanks. I was able to back up my save so I can go back to it whenever I want on PC or WiiU.
Tested and works fine with a JP title.

Looks like the save works fine going from VES (WiiU) to SRM (Snes9x) but not vice versa. It's possible that all I needed to do was shut off the WiiU while in-game so it doesn't overwrite the save with the WiiU's save state "suspend point" on next boot.

I tried the script by user mossywell here and it worked great with my srm file

Is this really safe to use? I ran it through hybrid analysis and got a whole lot of warnings about anti-VM tricks, ransomware, registry edits and keylogging.

(I had to replace the . and / with space and remove the h word that goes before it because I'm new.)

This is a wonderful project!
My dream has always been to have some sort of way to synchronise save files between portable consoles (PSP, Vita, 3DS, etc) to PC emulators (retroarch and also maybe rasbperi pi and other dedicated emulation machines).
Thanks for your hard work! Hopefully the saves convert over cleanly.

I know the source is there but I am not smart. How does it work, in layman's terms, if I may ask? Like what are the differences between a VES and SRM file, how are they similar? Etc.

I know that VES files are the save files used by the 3ds virtual console, and SRM are the save files used by emulators. I don't know any more detail than that.

Yep. I would like to know how they differ - if nintendo structured theirs differently for certain reasons, if one has X data and the other has Y data, etc

i have been trying to get your program to convert my chrono trigger save file from my pc to my new 2ds xl but it isnt working. ive tried using both headers that appear on the game id list (110B and 110D) and using both jksm and checkpoint to restore the save. the save file works on my pc but i cant convert it over to the 3ds vc release. i have no idea what im doing wrong if anything. ive spent like 4 days asking people in the homebrew discord. i cant figure out what im doing wrong. is it the game thats screwing it up, am i doing something wrong? please answer.
