   So g2f pic is altering portb. Additionally, it seems to have an impact on the US driver.
   
   When I:
   1. Load US driver
   2. Load .xex generated by g2f
   3. Switch OS off to get the US driver back
   I cannot load anything more. Some data are loaded (still with ultraspeed), but program hangs.
   
   After each g2f pic displayed, I need to reload the US driver for everything to work correctly again.
   
   If I can't find out why is g2f breaking the US driver I will convert pics to the simple bitmaps and display accordingly. These pictures don't use any special effects (DLI, PMG, etc.) so it should be easy. I will, however, lose the fade in/out effect ;)

   OK, problem solved. I converted g2f pics to simple bitmaps and display them without using the sophisticated mechanisms used by g2f.
   
   Now nothing interferes with the PORTB and ultraspeed driver works as expected.

   The only drawback is that US driver ignores the $41 [SOUNDR] register, so the I/O is noisy.
   
   Well, I guess I can live with that :)
