ok so i got drawn to life to work
as well as brain age 2 with this method
when writing it using u disk turn on force R/W and put it on safe mode
this doesnt work for donkey kong tho
g6 wont have lags on most games
with the r4 you need a good memory card for no lags on castlevania but not on g6 because there is internal memory
also if you want slightly better download play go with the g6
and the g6 is the only card available that can connect to the wii
