Retroarch android FBA core keyboard "F2" Service Mode for games

Hi everybody My question is: How can I get game service mode on android retroarch FBA core?

With mame 2014 core we can press “L2” access game service mode then edit “input(this game)” config service key…

Also please look my thread:

FBA press “L2” doesn’t work that way lol

I got FBA massive cheat codes they all with .ini file

How can I made them works on retroarch android fba?

Thanks again!!!
