Castlevania plays just fine, but everytime the game is turned off, this problem occurs. when the DS is turned on, the r4 menu is corrupt and i have to format the Microsd card all over again. i've done this about 3 times since this morning and it's really getting on my nerves. does anyone encounter the same problem or have any solution to this? any help is REALLY appreciated. i'm using version 1.18 of the firmware, by the way.
