    I backed up MH4U with GW, but it made 2 parts/files. Is there a way to merge them into 1 3DS ROM? Also, how would I extract retail cart save and import to GW? Thoughts appreciated :)

    Just format the SD card to be able to have files bigger than 4gb,
    About the save I have no idea.

    It is a SDHC Card. How do I format it to support larger files? exFAT on Gateway mSD card is supported, but not exFAT on the 3DS SD card...

    Try navigating to the folder the files are in on CMD and entering this: "copy /b XXXX.3d0 + XXXX.3d1 MH4U.3ds" without the quotes, where XXXX is the name of the files.

    As for extracting the save, there's an option for that when booting the Gateway exploit, but I've not used it, so I'm not entirely sure how it works.

    How do I format the Gateway mSD card to exFAT and what cluster size do I need? Right now, it is FAT32...

    Connect the mSD to your computer. On the side bar, right click on the mSD and click Format. On the window that pops up, under File System, change it to exFat. I would recommend unchecking Quick Format, but this will make the format take a lot longer, so it's up to you. Then click Start. Once it finishes, your mSD will be in exFat.

    Do I need a certain cluster size?

    I left mine as default, and haven't run into any problems so far.

    Can't you just trim the ROM on your PC and then use it as is?

    Has anyone been able to extract MH4U save from retail cart and import to GW ROM?
