I am using M3i Sakura with all the latest update to play Castlevania Portrait of Ruins. It always random hang after about 10 minutes of playing. Anyone experience this problem? I have already try the US version or the UK version. Both game always have random hang. Is this game not compatible with M3i Sakura? Anyone know how to fix this? Edit: I am using 8Gb Transcend MicroSD It is good enough? or should I get another brand? If so, what brand?
