Ok what am I doing wrong
I have every version of Final Fight merged in my MAME directory and all run on FB Neo.
Now I download a ffight.zip from the Internet, patched it with the 30th installer from Github, and it said it was successful. I had my ffightae.zip
I put ffightae.zip in the folder
FB Neo does not detect the 30th anniversary. And if I double click many roms have wrong CRCs
