If you think this is Tegra format file that is used in Nintendo games, then you will be disappointed.
I can't figure out this texture.
Header size is 0x20
MAGIC is xtx\x00
Values are stored as big endian
0x4 is storing unknown data (it's not a type or layer count)
0x8 and 0x10 has one dimension, 0xC and 0x14 has another dimension
one dimension is 0x300 (768), second dimension is 0xC0 (192), each pixel is 2 bytes
Was testing it with r16, r8g8, bgra4 and b5g5r5a1, getting only garbage with and without deswizzling.
Any help will be appreciated.
