Hacking Possible To Dump Save File and Overwrite Back Onto Cart?

[thebib62]

Hey guys, I wanted to know if there's any way I can extract a save file from a 3DS game cart, do what I want with the save file, and then load the save file back onto the SAME 3DS game cart?

I have a Gateway 3DS, and know that I can dump the entire game, and the save file on the cart.
I need to know if I can send the save file back on to the same retail cart?

You need a cfw and either sdf or ntr to rip write the save depending on if you have a o3ds or n3ds. Also a few games have write back protection and can not be written back to the cart

I have an original 3DS, and SDF (savedatafilter?)
I'm trying to do this on Pokemon X/Y and OR/AS, will this method work for those games?
Which CFW would you recommend me?

Never did before (and I will not do) but you can backup/restore savegame data, dump your own cartridges all with GW Launcher...
You should download the launcher.dat by GW official page then put into your SD Card (that one big included with the 3ds), then setup your 3ds for internet and open the browser (don't care what version do you have...).
You should to go to this site: http://go.gateway-3ds.com and hold R, then, launcher.dat will be load and you should choose the options who you need.

I didn't nothing of those things but most probably the procedure is this

RXtools worked perfectly for me. Just use savedatafiler to export the retail save, do whatever you need to do with it, then use savedatafiler again to import the save back onto your cart.

Thanks, I just got RXtools running on my 3DS. But now I need to know how to install savedatafiler using this CFW. I have it installed using my Gateway under Gateway mode, but I don't see it while under this new CFW.

What games have write-back protection? I'm just curious..

Um... I remember reading it on 3dsbrew but can't seem to find it. I think it was linked in the ntr save plugin thread

Okay, so I got everything working, but now I have another issue. It seems to me that, if I start a new save file on my Pokemon games on a legit 3DS, and then try to play it on my 3DS running Gateway/RXtools, I get an error saying the save data is corrupted.
I formatted the game cart, and started a new game on my 3DS running Gateway/RXTtools, and now when I try to load the game on a unmodified 3DS it won't work either.

Is this issue known, and if so is there anyway for me to fix it?
