Deach - I would say it really doesn't matter a great deal what kind of brand microSD you get. I have a cheap Transcend one and a normal Sandisk one myself. There is no difference between them at all. But then again, some people would shoot Pino's head off for saying that there is no difference. Appearantly, some people have had problems with Castlevania: PoR (which I have written a full walkthrough for -- I am very proud of it) freezing. Appearanyly people have managed to fix this by switching to another brand of microSD (i have never had any problems like this with any game myself, and I play LOTS -- way too much :(). You could have a read
here if you want to, but I'd say it isn't a big deal.
Sorry about late response. Pino is playing Odin Sphere ^^;;;
