MaidParadise: Mezase! Maid Number One!

[artare]

Hi. Firstly, please excuse my bad english
Im new on this forum so i don't know where to start.
Currently i'm playing Maid Paradise Mezase NPJH-00099 (JPN).
Platform android, using ppsspp build 1.2.2
The game run fine, smooth, good speed. But when i tried on DLC (choose character in DLC), it just freeze whole emulator.
I've already copied the DLC folder (NPJH00099) into PSP/GAME, PSP/SAVEDATA, it still freezing.
Any suggestion?
Thanks
