Trying to make a custom font. Here's what i'm doing.

Load up WiiBuilder, choose System, 22, Regular, Yes.
Click Generate Image, Save as System_22.png
Got to folder run raw2c System_22
I then follow the tutorial, include header files, create U8 pointer, then try to draw text on the screen. This works....

GRRLIB_Printf(100,100,tex_font1,0xFFFFFFFF,2,"Hello World!",var);
this does not....
GRRLIB_Printf(100,100,tex_System_22,0xFFFFFFFF,2,"Hello World!",var);

No error, just nothing writes to the screen. Any idea what i'm doing wrong?
