Yeah... but it's not proposed for GTA03 to use NAND.
If people use it on GTA02, it's elective and nobody said it'll work on
100% of GTA02.
But, from what I have seen it looks like it will work on very nearly
almost all GTA02, since bad blocks seem to be very rare in the whole
flash device let alone just in that place.
So I think this is acceptable, backup filesystem on SD should work fine
