Romcenter

I have an old roms from 1998 and I cannot find any updates. It's king of fighters, samurai shodown, ninja mastesrs and bunch of neogeo trips. I'v tried to rebuild it using romcenter (for example ninjamas.zip) and then i saw that many file in this rom are missing (217-c3.bin, 217-c-4.bin to 217-c8.bin)??? Why??? I't worked with an old mame??? What did I do??? Who did I hurt??? I'm just a peaceful little man from a little town... Can anyone HELP me I'm desperate!!!

Yes, that's the life and death of roms.
Old neogeo roms were, for most of them, bad dumps.
So, they have been redumped and old roms are no more used. You must find new correct dumps, or stick to your old mame which can emulate neogeo, but not perfectly.

I bet your problem is you are missing the Neo Geo bios file. Search around, the .zip should also be placed in your rom folder

try to search it, by typing their file extension..
