es_systems.cfg.zip here is my es_systems.cfg - maybe you can some lines copy and paste to make yours work ... or you take this and change only the path to the roms. Hope thats helps.
Greetz,

Many thanks SSC_Jarod - NEO GEO is now showing up thanks to your help!
I've done some more editing and added in entries so I can also have the ''groupings'' of CPS1, CPS2 and CP3 games and they now show up as well.
So pretty sure I've sussed out the es_systems.cfg for adding in new systems and roms - thank you for your assistance.
I borrowed an XBOX 360 joypad and it works (once configured) in the ES menu, but also does not work inside any games / systems. Also I noticed that both the wired USB cable xbox 360 joystick and the PS4 joystick both only ask to detect the shoulder buttons.. not the trigger, or the analogue joysticks.. is that normal?
another thing is I noticed some games are being ''cut off'' at the top and bottom of the screen - I'm assuming because their upscaled ratio doesn't fit nicely on the screen - any way to force games to display nicely on a 1080p screen please?
Lastly if I can figure out how to use bezels and overlay artwork then I'll be a very happy person!
Thank you niabi for porting ES for us!
