Castlevania - Portrait of Ruin(E)

I'm playing Castlevania - Portrait of Ruin, every thing just fine. But some time when i'm playing it, it stop, every thing sttoped. The character stop, i can't do anything. And most of the time i press the Start button, the screen just go black, the music is still playing. Do you have any idea 'bout this problem?

I have downloaded the (U) version for a comparison. But it still the same. And i'm using a Super Card, firmware 1.83.

It has to do with your MicroSD card, if the read/write speed is too slow then this specific game will lag or even freeze. There's nothing you can do about it besides getting a faster MicroSD card.

That the only solution ey. I better saving money from now on

Hey, do you think that format my SD will solve my problem. Let's me know what you think.

not likely, it might help a little bit, but any improvement would be temporary.

I got the same problem too. The game freeze when i opened the start menu during the game.But when i bought the mini SD Rumble version it doen't freeze anymore.I heard that some games like that needs a faster SD card like my SD rumble.But some games takes a while to save when u use rumble version, for example :
Pokemon Diamond/Pearl version, when i played using normal SD the save time is less than 5 seconds,
but when i used Rumble version the save time takes more than 1 minute & probably 2 minute when
the massage "Saving A Lot of Data" appeared T_T.

I'm having the same problem with WO:2. When i tried to load, the screen freeze when the worm fall down. But i don't use the ptached version. So if i use the patched version it will be different.

^ the patched version possibly wont make any difference, the read write speed of your SD is important cause thats how fast your DS can obtain the data, if its too slow then your hungry DS wont get what it needs and youll freeze up.
On another topic im using the fastest kingston on an R4 and I recently had a few freezes on MK, any ideas?

Like the other guy said, you should change your mini SD or micro SD to rumble mini SD or rumble micro SD
