Problems with exporting spritesheets

[MacioU42]

Hi, I'm using JPCSP 64bit on Windows 7 64bit. I'm trying to rip sprites from PSP game (Patapon if someone needs the title). When i use File->Export 3D Scene it exports, however sprites are black and they export... on black background. Soo... they look something like that...

What's strange is that some sprites export on white background... sometimes they are white sometimes black. Is it a problem with my emulator or ps or it's just game's fault. I'll be really thankful if someone can help.
(and sorry for mistakes, english is not my native language)
