First of all, congratulations for this great emulator, it runs very well on my Galaxy S4.
Just one minor issue I'd like to solve. In pokemon black 2, sometimes in order to progress we have to do a ingame save (for instance, after the 2nd badge at the theater thing). However, my ingame save is not working, it says "There is already a saved game file. It is impossible to save..."
As they said I already had a saved game file and that was the source of the problem, I tried to delete the .dsv file... with no success

I am sorry if you have already explained how to solve this, but I couldn't find it in the forum.
Thanks in advance,
Gante
