Has save data that uses a higher update of the game then you have installed. Thinking you will have to buy the cart new in order to get around this.

 

Had exactly the same problem. Used copy of Smash Bros which was used with newest update...
If you know someone who's able to use Gateway, he can wipe (write a 512KB 0xFF file) your savegame (ABXY trick doesn't work). Then you can play again....
You may want to make a backup if something goes wrong...

 

Nope. The update is saved on the SD card, which you can't transfer because it's bound to the 3DS it came from. The game saves the version of the latest game update it was used with in its save partition.

So, the only choices are:
1. Update the 3DS.
2. Buy a new Smash Bros 3DS.
3. Wipe the savegame with a old3DS + Gateway.

 

If you mean ABXY, nope. That doesn't work. I got an old 3DS with newest update, that actually can access the eShop. I inserted the game, updated and wiped the data with ABXY and it didn't work. Even if you wipe Smash Bros. the game will still know with which version it was used with. So, ABXY only wipes save data and not the whole save partition.

 

I have the same issue - My personal copy of SSB was used on my old 3DS with patch 1.0.4. I was planning on playing it on my N3DS while I waited for GW support but got this error. There's an option to open the game without your save data, but I don't want it to wipe my save either... So I wait for GW before I play it on my N3DS

 

How can I "wipe (write a 512KB 0xFF file)" on the saved game? I have menuhax installed.
