Sims 2 Open nitro_texture file Help

[Hiddan]

Hello, I spent a lot of hours to try to access to the textures of the game Sims 2 Castaway on Nintendo DS. I success to extract files from .NDS. But files inside have an private "dot file" like nitro_*type of file*. I tried to open it with an hexa editor and I have coded an applcation in c# to try to read hexa without the header... But that has not really worked.

Without sample files nobody can help you.
