I already updated my device to 2.3.4 and converted Final Fantasy 8 by PSXperia tool 2.0 beta. The game cannot play and black screen is shown. This problem did not occure in PSXperia tool version 1.0 (android version 2.3.3). It will be a good news if you can fix it.
My device information
I knew the answer. I converted a crash rom file, after downloading a new one and convert it, it can be played.
