+T3 I2C currently has no ACK bits(should work without them its just inaccurate)(I2C works fine though)
+T3 emulation attempts to set GPIO1(reset button) as an output
+GPIO lines from misc chips to CPU are not implemented

 Fixed:
+make the headers belong to the main file of the target chip being emulated for specs
 remove specs folder
