Problem converting .bmp to .bin

[cixxx]

I want to include a rotating logo onto the top screen in a demo on the nds. the logo shall be in .bin format, but how do i convert it correctly? i already tried bmptobin.exe with no success. the program on the ds is working correct, the logo is rotating, but all the grafics of it are messed up, so it must be an coverting error i guess. any ideas?

i created my .bmp in photoshop cs4 which i want to convert to a .bin.

You'll be better using grit, see http://forums.devkitpro.org/viewtopic.php?f=22&t=17 for a brief guide

i solved the problem with gfx2gba.exe, it created a working .bin and palette for me. But i will using grit in the future looks like its the better solution for the future.
