Homebrew Injecting DS .sav to cartridge

[Kvothe43]

I want to inject a Golden Sun Dark Dawn (DS) .sav from a flashcart into a legit cartridge that I finally managed to get and will arrive in the next few days. I was planning on doing it with Checkpoint, however I'm not sure if the .sav and the cartridge will be in the same language (english .sav, possibly spanish cartridge). Would there be any issues?

From what I've seen DS games usually use the same saves between all of the western versions, however it's entirely dependent on the game so it's possible it might not work. Your best bet is probably to just try it and see, if it doesn't work chances are the game will simply refuse to load the save, I don't think it's likely that it will appear to work and cause issues later on.

yeah, it may work. you may have to hex edit. I managed to get a Japanese save file to work on either EU or American game on the wii/vwii. it was chocobo's dungeon iirc. not very hard to do really. hex editing is very easy if you compare two saves.

It is possible but you might need to use desmune to open your flash cart save and then save it in dsv format, and convert it back to raw save format,

Thank you! I might come back to ask for help about the editing, never done it before haha Hope it's not necessary!

Thanks for the tip and the tool! Can you let me know what is the reason to go through that process?

You need to convert if your flashcart save doesn't load on the retail cart.
