Tried with two different SD cards, 2GB and 16GB, and this last one, formatted in exFat and Fat32, with 3 ROMs. The 2GB one with only one ROM. In this case, It shows one blank box, appears a loading bar for 2 secs and... nothing. The flashcart was working absolutely fine with 2.0 or 2.1, I think it may have been the updating process when updated to 2.6. Don't know what to do.
