NeoGeo not working in 3.0

[evangeliz]

Hi guys,

First of all, thanks for creating Retropie and all the hard work.

I did search a lot but couldn’t find anything about this.
I’m having an issue with neogeo games. They don’t work anymore.
Before saying it’s due to the rom set, they worked fine in Retropie 2.6 but in 3.0 they simply don’t work, FBA gives black screen, lib writes a few lines and quits
gngeo was the one that worked best before, but here also he starts decrypting and quits after that.
I prefered gngeo as Metal slug roms seem to work best there.

If somebody could help me out that would be fantastic. :)

Did you put the bios file called NeoGeo.zip into the neogeo rom folder?

[evangeliz]

uhm, ok, I learned something extra today :shame:

Got another question though.

Where do we config the Neogeo buttons?

In 2.6 it was in /.gngeo/gngeorc, but this file doesn’t exist on my 3.0 system.

Its in opt/retropie/configs/neogeo

[evangeliz]

Not on my system though.

And I opened the other files, nothing key related can be found.

I did find this though in emulator.cfg

/opt/retropie/configs/neogeo/retroarch.cfg

but this file doesn’t exist in the folder

Update the retropie setup script then do a binary update.
Maybe that will solve the problem?
I have it on mine!

You can just create it – by default its not there in 3.0.0 – or gngeo will create it if you save some settings via the GUI.

You can create it with
“sudo nano /opt/retropie/configs/neogeo/gngeorc”

yeah you can create it and use this as a template to what you need to put in the actual file itself.

Super,

That worked out great, but unable to get the joypad to work, all buttons work though.

Anyway, I’m giving libretro fba a chance, and they seem to work, I just can’t seem to find where the key config is.

In FBA it’s rather easy (fba2x.cfg under FBA folder).

Any chance of a hint on that?

Example line (it goes in “gngeorc”):

p1control A=J0B0,B=J0B1,C=J0B2,D=J0B3,START=J0B6,COIN=J0B10,UP=J0a1,DOWN=J0a1,LEFT=J0A0,RIGHT=J0A0,MENU=J0B7

# Meaning of the code:
# Kxxx : keyboad key number xxx
# JxByy : Joystick number x Button
# JxAyy : Joystick number x Axe yy (use a lowercase ‘a’ if you need to invert the axis)
# JxHyy : Joystick number x Hat yy
#
# by the way, you can define a button multiple time, for example A=J0B0,A=K123,etc..

You can get your button codes by using “jstest”

The key config for FBA-LB is the retroarch.cfg one in the fba directory.
