Playing crosswords DS and it suddenly froze. Checked the DSTwo/cart and the MicroSD is no where to be found. I don't know if this is classic DSTwo story or not, but the SD card slides in/out fairly easy. I just used a 2nd sd cart to test a theory and the DSTwo launched the microSD across the room. Still can't find my lost SD card :\ I guess this is another advantage Cyclo had.
