I do that with other games like PSO, such as Super Smash Bros., and Animal Crossing... No corruption for me, thanx.
Same here. Also, don't try and set up your internet connection with an unnoficial memory card, it has a chance of wiping it.
first, sorry to hear about your corruption, second, when you corrupt in pso only your pso data has to be erased, nothing else
Actually, it quite often erases everything.
Theonly reason i hate about corruption is the fact im losing all my guild cards they are very important to me very important people are on them and the fact that grandmasterT will be gone

:'( good thing i havent experienced it yetalthough i might have jinxed myself right then

.
Can you copy GCard files? It's worth a try...
