ROM Hack Transporting .sav file to 3DS Virtual Console Pokemon

Ailuros27 · May 20, 2016

If you plug your old Pokemon game into the Retron 5 and it still has a save, then perhaps. You'll need a way to run homebrew on your 3DS. You'll need to move the save from your Retron 5 to an SD card. Then plug that into a computer and use the tool I linked above to convert that save to the proper format. After that, rename the new save "sav.dat" and use Homebrew like svdt to inject it into your game. I'll leave some links to helpful threads here:

I had no idea what a Retro 5 was until I googled it and the EMS would probably work but not the Mega Memory Card to get the save from carts and put it on the EMS so I doubt your setup would work.

Sorry, Retron 5.

I was able to extract the saves using a Retron 5 and migrate the pokemon over using Freakyhax and svdt

No more fuss. Lemme explain this.

- Get a .sav file, either from an old playthrough, or from the Internet. Like this one, for example.
- Start a ROM of the game in an emulator (like VBA-M) with the same name as the sav and in the same folder as the sav.
- The save should load
- Export the battery save (VBA-M: File > Export > Battery File)
- Start a save on your 3DS VC
- Export the save through a save manager (like JK's)
- Get to the 3DS save you dumped
- Check your battery save's size. It has to be 32KB to work.
- Rename your battery save to sav.dat
- Replace the sav.dat in the 3DS save with the sav.dat from your computer.
- Reinject your save through a save manager (like JK's)
- Boot your VC game
- ???
- Profit

I did that with Mario Tennis 3ds VC and it shows a message which says that save is corrupted and will be deleted.

How to solve that then?

It is possible to transfer the .sav through to the pokemon virtual console for red. Rename the .sav as the exported file with extension. keep the secondary file with the new file.

Then import using checkpoint.

I did this exact method when i extracted my gamesave from an Original Gameboy Cartrige using a Gameshark for GBC and Windows 98. Worked like a charm when i used checkpoint in cfw on 3ds.

I just found out that i needed to import other files than .sav one: when backing up Mario Tennis' save, it's folder contains 3 files: rsm1. dat, rsm2.dat and sav.dat. I had thought that only sav.dat file was needed, due to fact that i only imported similar one to Bomberman 64 on my Wii U.

I just imported the new renamed sav.dat and the other 2 files and was a total success! =]

Yeah, you're supposed to just replace the sav.dat and reimport the save. If you mess with any of the other files in the save it obviously won't work.

Wiiu U's Bomberman 64 also backed up other files than sav one and i imported just the sav file and worked.

The Wii U and 3DS are two very different consoles. The emulators probably weren't even written by the same people.

Hey folks! Sorry to bump an old thread--this is what Google came up with so I hope I'm not bothering anyone with questions that have become common knowledge.

I'm trying to import my old Game Boy saves to the 3DS VC in much the same way, albeit for the purpose of sending them to Bank via Poké Transporter, and ultimately, to Pokémon Home. How safe is this? After homebrewing a 3DS and loading my old saves, will logging online to transport them brick my system? Would love to hear some guidance from those who have tried this.

No, there has never been such a thing on any Nintendo console, if not (to the best of my knowledge) any gaming product

Be advised that you can dump your GB saves using a Game Boy Player on a Gamecube capable of running homebrew. (Running homebrew on a Gamecube is easy if you have a modded Wii with Gamecube memory card slots, or you can invest in an SD Media Launcher.)

Also be advised that you don't have to do a full CFW install on your 3DS and can apparently just install Picchax, if the above replies are any indication.
