Not sure what are you talking about...

Have you added my iOS net play code to android build? On 0.139?

yes,    I added iOS net play code to android tag MAME4droid 1.5.

and I found key event synchronized, means two device got equal sequence of 
input. but the output was not equal. 

for test, I recorded all input keycode sequence to a file， then replay it in 
two android phone. 
result： 
1)  the same device got same output sequence, but different device got 
different output.
2) It is interesting when I debug, I add some log code, then the output is 
different on the same device.
