Uploaded new version with import/export option. tested on v-mh3u.3ds.
Doesn't work for me.
I get this output:
MountSaveData(): 0xC8A04555
fuck. need to format save data...
2nd mount, almost failed...
I'm trying it with .3DZ named to 00040000000B1D00.3DZ (I have the european game)
Did I make a mistake?

for old games using normal encryption: common elf, need uniqueID, and hash/rsa key from 0x400~0x600 in xorpaded exheader to generate CCI rom.
for newer games using 6.x save encryption: must hack into original exefs/patch, find all apis we used and merge these address into my asm template now. use original exheader with slightly modification. must be CIA format to workaround fingerprint change (due the slightly modification). I have plan to use common elf instead hardly find symbol in exefs, but don't except too much.
thanks for the explanation. I have another question though
Is it possible to modify weapon's stats? like change attack power, elemental attack power etc?
If so, would you consider adding this feature in a future update?
That's my main goal as well. I know the saves are not 100% identical, so we need to extract and decrypt the MH4G save, edit it appropiately (just a minor edit but otherwise guildcard stats are fucked), encrypt it and inject it to MH4U. That will work.
exefs built from my standalone elf just discard by system. when I launch game, my patch doesn't get load. without an interactive UI, it's hard to select save/load action on startup.
and the patch I post based on original game takes more manually works to merge codes/exheader on each build action.
I'll try again in weekend to get the L/R UI version patch accepted by MH4G, or decide use some workaround to support MH4G's import action, for eg, use new folders "mh4gin" for import.
sky3ds works like retail carts. so the problem is same, if your game used 6.x save encryption (6.0.11 keyY), the *.sav saved in un hacked console is incompatible with GW's rom.
I remember GW tried to fix the save compatible problem but in newest 3.0.x firmware, they still using bad key in GW mode.
I have a idea, if you have a friend, who play MH4 with cyber save editor, you can grab his card id and replace you template.txt, to burn a card with same id to his card.
once your want to transfer your sav to GW mode, send your sav file to he and he can write to card then extract system/user1 for you, that can do a import to GW mode's rom
another workaround, I havn't test it yet, is use a customized CFW, which can export retail MH4 save into system/user1 file by SaveDataFiler. the preparation steps is a bit complex but some Chinese MH4 user reports a success.
gw 3.0 supports the correct save key, but only in classic mode.
when (if) gw supports the correct save key in gw mode, we can rip from sky3ds, ok, very good.
thank you for all of your advice and help!

4 launch mh4g rom and enter game.
5 system,user1~3 will exported to mh4g folder.
how to import back:
1 make sure you've already installed mh4g_down_10_rc_eximp.cia

3 you can copy 000400000011D700.sav to PC to prevent data corrupt.
4 place files what you like to import to game.

online save data editor. limited to change hunter and otomo's name.
I Second that. Can we edit more than just points, name, and money? How about pouch editing? Or weapon modding?
of course it is possible, but who will put in the effort to discover what is where?
Yeah I guess your right, but its mostly trial and error if it's actually in the data. I'm willing to go through it and post what I find. It's just i want to know if its in there before wasting time and effort.
Sorry if I missed something, but would it be possible for this tool to be ported over to ninjhax?
