I use newer original Gnuboy sources as Base for the port. I borrowed the menu from Joyriders port, because I think it's good.
What do I plan?
-speed improvements: Gnuboy run (unscaled) with 60fps @ 200mhz ;-)
-remove Savestate Bug (the first savesate is not loadable, you have to save twice times)
-add Screenshots to Savestates
-changeable Gameboy Player Backgrounds
What else do you want?
-Overclock in menu?
-Better scaler for Fullscreen?
Please write me a comment.
