I've been wondering about this one for a while.
For games with NAND saving would it be possible to rewrite the ROM, as it is stored on a rewritable NAND chip, or is that part of the NAND write protected in some nonrevertable way?
If possible then this could serve as a sort of flashcart, minus saving for games not using NAND saving, and it would work on all current and future firmware versions as it would be equivalent to a retail cartridge.
