    Can you write to the ROM of a Ds cart, like injecting a .nds rom of the same size or smaller into the eeprom...

    ROM stands for READ ONLY MEMORY. Therefore, it is not possible to write to it.

    somewhere
    ROM means "read only memory" meaning you can not write to it. So, no.

    nope, Read Only Memory.
    i doubt there is a simple (if any) way to write a game...

    however you can read and write saves

    You can write saves to dsiware with a9lh. How do think the hacked save is injected to dsiware downgrade?

    Is there any 3ds software that allows you to do this, because I have only seen software to load saves to gamecarts

    it would be possible, but yeah if there is no tool to do it yet, it's just because of that - someone hasn't made it yet.
    but sure it is possible from all the 3ds hardware and software - pokemon bank does it to dsi enhanced carts right :)

    You'd need arm9 access to read/write saves to DSiWare, as they're stored in NAND.

    that doesn't really matter for you about what the guy above said because you asked about carts not dsiware, anyway of course we need hacks to do custom stuff.
