Install mame4all-pi via the RetroPie setup script (Option 2 “Source based installation” then select only mame4all-pi) Then edit es_systems:

sudo nano /home/pi/.emulationstation/es_systems.cfg

And replace this:

DESCNAME=MAME 
NAME=mame 
PATH=/home/pi/RetroPie/roms/mame EXTENSION=.zip .ZIP 
COMMAND=/home/pi/RetroPie/emulators/RetroArch/installdir/bin/retroarch -L /home/pi/RetroPie/emulatorcores/imame4all-libretro/libretro.so --config /home/pi/RetroPie/configs/all/retroarch.cfg --appendconfig /home/pi/RetroPie/configs/mame/retroarch.cfg %ROM%" # alternatively: COMMAND=/home/pi/RetroPie/supplementary/runcommand/runcommand.sh 1 "/home/pi/RetroPie/emulators/pifba/fba2x %ROM%" PLATFORMID=23

with this:

DESCNAME=MAME
NAME=mame
PATH=/home/pi/RetroPie/emulators/mame4all-pi/roms
EXTENSION=.zip .ZIP 
COMMAND=/home/pi/RetroPie/emulators/mame4all-pi/mame %BASENAME%
PLATFORMID=23

Then reboot. Roms need to go in /home/pi/RetroPie/emulators/mame4all-pi/roms (you need to create the directory)
