Mame 2003 and 0.78 roms not working

Hi, I install lakka from usb on an old computer.

Update all cores from online updater.

put mame 0.78 roms in to roms directory and Scan that directory

but none of my mame roms are working (all of them mame 0.78).

An suggestion?

PS: snes n64 genesis sega are working only mame not working

Yes I had a similar issue and it seems that the system folder was not set. Try setting a system folder (different than the default - empty -) to see if that works for you… if so I think the issue should be reported in the github core page.
