used a trick I posted here to access card1 game's save under gateway.

can export files from Monster Hunter tri G to sdcard's sde folder.
mh3g's savedata is not encrypted in game so name/money/point is all plain data.

the MH3G one working for AMHJ code, JPN region, and the 3U is for AMHE, 3P is for AMHP.

How to use:
if your save is for mh3g.3ds format, just rename SaveDataExporter.3DZ to 3ds, if you using 3dz you need patch SaveDataExporter.3DZ with the same card id to your Game.
in 3dshelper, select your 3dz rom, export a bin file, and select savedataexporter, import the bin file just like treat a game.

in demo version (a1), when this exporter launched, all files will be export to sde folder.
new version (L/R): press L to import, R to export. files will place under mh3g folder in sd card

TODO:
1. 6.x MH4G support with additional decrypt.
2. Import
3. titleID batch changer to match other games.

yes, but like vc rom, we need a "Generator" to migrate titleID / gamesave flags from these ROM to exporter.

link removed, may export bad user1, please use new version on page 2

install using bluebigmenu or devmenu, and launch your mh4g from GW card.
(maybe something wrong in my code, if you SD havn't a mh4g folder, create one first.)
exported system/user1 files will placed under your SD card "mh4g" folder.

sounds strange.
the first two lines means source file is ok, but detestation files under sdcard/mh4g create failed.

next three lines means mount failed at all.
do you have your sav file and card id header exported by 3dshelper?
I'll try to reproduce it on my GW.

do you need the card id? and my .sav should be the same as the game because it created from the card
