I’ve recently acquired three different Wii Sports Save Dumps (Thanks skibur and BigRedPimp). I’ve been going through them looking for interesting stuff.

You can find the dumps: here

data.bin is a Wii Sports save file with one registered Mii.
data2.bin is a Wii Sports save file (from the same Wii as data.bin) with two registered Miis
datat3.bin is a Wii Sports save file (from a different Wii as the first two .bins).

Differences in the files (Thanks, davr):

data vs. data2
f1c0 - 2f1fb, 2f385 - 2f3b0, 2f488 - 2f4c3

data2 vs. data 3
f0c8 - f0cb, f12b - f12d, f1c0 - 2f23f, 2f2c9 - 2f2cd, 2f305 - 2f343, 2f385 - 2f3bf, 2f41e - 2f424, 2f489 - 2f4c3
