Hallo, i have hakchi2 newest vers. running good so far. But Mame Roms and neo geo are not working

. I have installed the needed cores, but i don't know the location from the bios files. I copied the bios files extracted to the extracted neogeo game folder, after that i packed it to zip an addes like a game in hakchi2. I have read that the command line commands needed for the path, but that worked not for me. Someone write to create own fodlers i am a little bit confused. That Mame and Neo geo not worked. I tried both files neogeo.zip and pgm.zip. Help needed!!! N64 SNES NES works great.
