Thank you so much, you killed the charade.
on this line in es_systems.cfg I just put the emulator name sub-replacing with% SYSTEM%

<command> python /usr/lib/python2.7/site-packages/configgen/emulatorlauncher.pyc% CONTROLLERSCONFIG% -system fba_libretro -rom% ROM% -emulator% EMULATOR% -core% CORE% -ratio% RATIO%% NETPLAY % </ command>

you do not know how much time I lost in it looking in forums and topics, and I saw nowhere when it was explained that this parameter had to be changed.

Thank you very much for your help.

@bkg2k
Thank you very much for your attention and help. I even looked at the log and had not identified anything strange, but after reading @voljega's instructions and making the change on the command line, I saw that the log contained a part that was -system cps3 -rom

I was able to solve the problem.
Thank you very much for your help.
