hi. to add new mcu is not easy..
atmega48,88,168,328 have different SFR position in memory.
not only add new chip definition... you need set correct position .. then all will work good..
now I can compile source code then I try add this MCU to code ..but I don't have more free time..
look to this document:

here you can see what are different..
if have more free time then I add new chip..
