Hacking [Need testing] 6.x encrypted Retail Cart Save convertable?

[MelonGx]

Requirements:
- 3DS with 6.0-9.2 firmware (DO NOT downgrade, DO NOT use 4.1-5.1 consoles instead)
- Gateway
- A 6.x encrypted retail cart (later than mid-2013, such as Pokemon XYORAS, MH4G, SSB, etc.)
- emuNAND ready
- SaveDataFiler CIA installed

Instruction:
1) Play retail cart in 6.0-9.4 SysNAND (NOT emuNAND classic), then do a save.
2) Dump the retail cart save and rename it into 000400000FF40A00.sav. (Card1 game only)
3) Dump the retail cart ROM and rename it into .3DZ.
4) Enter the emuNAND and mount that .3DZ.
5) Use SaveDataFiler to export CTR card.

If step 5 is available, then it's convertable.
If not then it fails.

Saves from Pokemon retail cards are 1.048.576 Bytes insted of 524.288 Bytes.

queno138 informed me that CFW with SDF could help, so i added it to my tutorial.

Here are some reports of RetailCartSave on GW-Classic:
SysNAND 4.x-5.x / RetailCartSave 2.2 - OK
SysNAND 4.x-5.x / RetailCartSave 6.x - Corrupt and initialize
SysNAND 6.x-9.x / RetailCartSave 2.2 - OK
SysNAND 6.x-9.x / RetailCartSave 6.x - OK

Here are some reports of RetailCartSave on SysNAND 9.4:
Saved on GW-Classic with SysNAND 4.x-5.x / RetailCartSave 2.2 - OK
Saved on GW-Classic with SysNAND 4.x-5.x / RetailCartSave 6.x - Corrupt and initialize
Saved on GW-Classic with SysNAND 6.x-9.x / RetailCartSave 2.2 - OK
Saved on GW-Classic with SysNAND 6.x-9.x / RetailCartSave 6.x - OK

This post is talking about SaveDataFiler exporting RetailCartSave on SysNAND 6.x-9.x / RetailCartSave 6.x.
CFW is locked into SysNAND 4.x which doesn't have 6.x decryption.
(If a 6.x Retail Cart Save is readable by CFW, then it has been already saved on GW-Classic with SysNAND 4.x-5.x, which forces gerenated the save into 2.2 encryption.)
So if only my theory is wrong, CFW will not work for this case.

Do you mean 6.x-9.x SysNAND just makes Classic mode using 6.x encryption, but GW mode is still staying at 2.2?
If yes, then the conversion becomes unavailable.

- emuNAND ready

Instruction:
1) Play retail cart in 6.0-9.42 SysNAND (NOT emuNAND classic), then do a save.
2) Dump the retail cart save and rename it into 000400000FF40A00.sav. (Card1 game only)
3) Dump the retail cart ROM and rename it into .3DZ.

Only possible if Gateway doesn't interfere with forced encryption and filesize matches (accepting .sav).

I don't think this will work either. Sad Workaround is owning the eShop Title and to use the Savegame Transfer Title.

Best chance would be porting CFW to 9.x and work on stability with sysNAND at least 6.x.

I've tested this with MH4G when liomajor shared his tutorial and it doesn't work, CTR card shows up as corrupted.

has anyone actually tested using the save transfer tool to a fake cia, iirc it just scans for a installed game using the same titleI....doesnt really matter if it was legit on the eshop, just as long as the system see's there is a eshop title there that matches the cart, so legit cart+save data transfer tool+ cia installed version of the game in classic mode run on a 6.x base system *should* work i would imagine

 

[GolfDude]

i tried that and it doesnt find the cia file on the system

Or a method to Launch the 4.x CFW o a 6.x+ sysnand. I tried a 4.5 emunand classic in a 6.2 sysnand and the 6.x sav works.

If card1 gamesaves had the capabilities of having a softtop this I gotta see.
