First of all, sorry for my bad English.
After that, I need simply to print an image at screen (to do a sort of a splash screen) but my program has to work in kernel mode.
I tried OSLib (the Sakya's mod too), the LUA Player's Graphics.c, the PNG/GU libraries... but all work only if I don't use kernel mode (so in user mode)... but I need to use kernel mode :°°°°°°°°°°°°(
Could you give me an help or just an hint to find a simple image library for PSP to print at screen an image in kernel mode please?

Thx to all will help me ;)

Afaik you gotta get yourself a pointer to the framebuffer and draw manually... other ways you can do this would be by hooking the GE driver functions I guess.

Pure kernel mode programs are ugly (well, unless they are simply PRX modules for VSH or games, in which case you don't need to print stuff on screen anyways).

Make a user-mode program which will do the drawing and load a kernel mode PRX which runs the functions you need.

Not always possible... sometimes you gotta go the ugly way through kernel prx files, especially when other user modules using libc are hogging the whole memory range to themselves...

If you allocate a block of raw user memory from a kernel module to be used as the display list, then you can draw with the GU from kernel mode.
