    I was wondering how to put downloaded .3ds roms onto a hacked cfw running arm9loaderhax. Could someone direct me to a guide or give me instructions.

    .3ds files cannot be used on CFWs only on flashcards like Gateway or Sky3ds. .CIA should be the files you are looking for. They install on to the home menu.

    If you insist on using .3ds games you need flashcart (like sky3ds). But if you wanna you can transform 3ds games into cia format and then install them. Or just download the cia version of the game. Or even easier just use freeshop to download and install all the cia s u want

    .3ds roms contain extra unused data. .cias are trimmed meaning they don't have that extra data

    ROM memory is made in powers of two (i.e. 1GB, 2GB, 4GB, etc), while most games are not. A ROM chip of the smallest possible size is used so the game will fit, but that still leaves some unused space left over. Tools that dump ROMs dump the entire chip, even the unused bits (which can be removed through a process called "trimming"). CIAs are basically just files that don't need the extra padding. When converting a ROM to a CIA, the conversion process ignores the unused bits in the ROM, and is never added to the CIA, since it's not needed.

    You stated the only real difference. 3ds roms also have header (so no online play ban) but cias don't

    also arent cart games programmed to store the save on the game cart so when you convert them to cia how do they still save

    They are made to save in a certain location on the sd card. Can't remember where.

    well the freeshop can't download gamecard only games converted to cia if they had data base to store the cia files of those games the freeshop would be even better

    freeshop downloads eshop games from cdn (nintendo's servers). Their is no way to add 3ds to cia roms.

    most people use it to pirate anyway why would you want to download a game you own when you can just dump your own copy quicker

    Well, if you really want something like that, why don't you create a .3DS freeShop and set up the servers to host the .3DS ROMs?

    well they would not shut it down they would just patch it like make an eshop update and also update the servers so purchases are tied to nintedo id instead of console
