Hehe, that file is a mystery to everyone (well, almost).
It sets up the interrupt vectors (yes, I know you know that). It makes
It declares interrupt handlers for all vectors, reserve_interrupt()

This declares a weak alias IRQ6, that by default points to UIE70(). The
In mpeg.c, the IRQ6 function is defined:
Now the linker uses the "real" IRQ6 function for the vector.
It is just a way of not having to edit the vector table when using an

Not really, but is a simple lcd_invert_rect() call to create an inverted
If you really feel like doing some tricky code, try optimizing the
Or maybe optimize the lcd_write() code in lcd.c if you feel like hacking
