Hi I have a Supercard dstwo flash card and everything works okay exept that sometimes the screen glitches when I'm playing specific ds games (castevania dawn of sorrow, Mario & Luigi Bowsers inside story) and I find that the rom selection menu is a bit slow plus pokemon black 2 freezes at the pokemon worl tournament :'( is it posible for me to fix this ??? or change use the r4 firm ware or dstt firmware instead of the supercard dstwo firmware ????
