Use clrmamepro (which run fine on linux with wine and macos with crossover) to build valid romsets with dats from the dats directory. fba dats are NOT mame dats. Don't report issues if you didn't build a valid romset.
Samples should be put under <SYSTEM_DIRECTORY>/fba/samples
Use this command to build : make -f makefile.libretro platform=rpi2
