I have an old pandora battery I made back when they first came out. I used it alot then but it has probably not been used in like 4 years. Do you think that the battery has gone bad due to inactivity? Also, I forget if the battery has to be at a certain charge level to work; that could be the problem with my impatient self....

I also have already remade my MMS using PSPGrader and RainMMS, alas, to no avail.
