Gamebuino forum

I'm trying to build a legend of Zelda port and I would also like to build my own Gamebuino. What I would like to do and it wouldn't be hard is to make the regular 8-bit version for the 84x48 screen but make a companion in color for those who have built upgraded versions.

My question is has any one so far been able to get a 256K LCD to work with the Gamebuino libraries.
