Jams in Castlevania: PoR NDS

Erm, i am using a Supercard lite with Kingston 1 gb memory card.I am always having jams when entering into the teleporting portal. It is kinda irritating. Can I know of a way to solve it?Thankz in advance

Castlevania is one game which isn't very playable, you're lucky you just have jams, many people experience freezes where they have to turn their DS off before it will work again.

so there is no way to solve it?

Not that I know of, not besides buying it, I heard it was worth it too.
