What the funk!? PSP 16 bit storage method - please help!!!!!

After a lot of swearing and cursing I've noticed that 16bit pixels are stored on the psp in lo-byte hi-byte order - this is for real? Really annoyed the skd blit sample does not mention this. Have I made a mistake somewhere or does the following genuinely happen? - Write
0xFACE to a short in memory and it will store it as 0xCEFA?

Some help - any help - with the 16 bit format on the psp would really be appeciated. Tried asking this question on a number of threads, but apparently nobody around to respond.

jubber,

PSP is little-endian system, the same as Intel systems. This is opposite to the network or Unix big-endian system.

Look at Wiki or Webopedia for more info about endianess.

Best regards,
Bulb

Oh monkey pants - so it stores bytes big endian (msb is on the left) but bytes within shorts or ints little-endian. Thanks for the tip - I suppose one plus side is targas are already in the right format for memory.

Cheers,

God I hate little endians. With their tomahawks and their facepaint. Little bastards.
