If you have this error simply set rewind_enable = false in retroarch.cfg
EDIT : in the /home/pi/RetroPie/configs/all/retroarch.cfg
regards
Ps: pifba retroarch core is slower than pifba binary, however in my sistem pifba binary doesnt give sound in some games, as retroarch plays the sound ok.
omg, thank you whise.
