what mame are you using ? Mame2003 or Mame2000 ? to get mame to work, you need to put a command line change. In the command line box, it will say /bin/zip. For mame, you have to change it to bin/mame2003 or bin/mame2000, depending on what version you're using.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.
