Hey, My Flashcart: http://www.nds-card.com/ProShow.asp?ProID=507 I used the kingston 8GB on that page because i'm lazy. For some reason, whenever I use my R4 for a long period of time, it just stops working. After inspecting, the MicroSD is empty. However Windows made a load of .chk files from the nothing. I ran these throgh a program and it isn't exxactly helpful: Warning: Spoilers inside! Now, I don't have much data that I care about, but this has happened twice now and I really don't want it to happen again. Anyone encountered this before?
