Thank you
you probably need the bios for those (google them) and modify the config.cfg for retroarch to map the bio directories to that folder

you need the right version of neogeo.zip in ~/games/MAME

Thank you i just run them by Retroarch
Thank you Johnisa I could it by retrtoarch but how modify the config.cfg ?
Try using winscp to get into the file system. The config file should be in ./config

Thank you for helping 
Sorry to bother, but I downloaded the neo geo zip and put it in the MAME folder, how could I map it from the retroarch config?
Easiest way is to ftp into it, navigate to the . config file and edit the file

I would make a bios folder in the retroarch folder somewhere in the same directory as the .config file. Then change the .config file to the directory of the bios folder.
So to change the .config file to the directory of the bios folder, how would it look? @Johnisa
I think it’s ./retroarch/bios/
If you’re using winscp you can double click the address bar near the top and copy the directory.
Here’s how I set it up. Also I didn’t put it in a bios folder. I used a folder called system instead.

This makes so much more sense lol, I was lost. Thank you
One last question, did you get the neogeo.rom from unzipping the neogeo.zip? @Johnisa
