SPI ???????

I'm putting together a full color gaming library and I was wondering about using the SPI. My LCD uses SPI and seems to use the same pins as the Gamebuino libraries SPI but it's written in different way than the Gamebuino.

Can I use the gamebuinos SPI functions and definitions instead of the LCD's.

Im getting close to finishing my Gamebuino library for full color.

Can some one please tell me if it is possible to use a different SPI code set than what comes with the source for an LED. Are they interchangeable can I swap it one set of SPI code for another?
