@Darksavior Mine are all CHD as well. lr-neocd seems to fail to recognize my BIOS files even with proper matching SHA-1's.

I found what was the cause of the same problem for me, i'll share with you in case it helps : my games were working very well with the NeoGeo Bios in the folder "fbneo" while the games were in CUE with SUB IMG and CCD.

When I compressed the game files in CHD, I also had the segmentation fault.

So I did exactly as @Darksavior : the BIOS files (000_lo.lo and neocd.bin) in a "neocd" folder that I created in the bios, and not in the "fbneo". Now, using the lr-neocd emulator it works well!

THX guys and good luck to the others.

Still no luck for me. I had those files already in a neocd folder in my bios directory along with some more, so I deleted the extras and tried again, but no luck. lr-neocd still says it cannot find the BIOS files (and it appears to be checking in BIOSDIR/neogeo which has them already) and the two fbneo emulators both segfault after the bios starts up.

@zerojay If you're positive it's not seeing the bios, and you've double checked the hashes, then you can try this:
Uninstall and then reinstall lr-neocd from source and open the rgui to check: "Settings","Directory","System/BIOS" and make sure it points to /home/pi/RetroPie/BIOS

I ended up using the lr-mess core for this instead. Seems to be working well.

I found that your naming conventions are not in line with the other systems, also it wont be picked up by most themes because of this.
My es_systems entry is as follows:

 <system>
    <name>neogeocd</name>
    <fullname>Neo Geo CD</fullname>
    <path>/home/pi/RetroPie/roms/neogeocd</path>
    <extension>.cue .CUE .chd .CHD</extension>
    <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ neogeocd %ROM%</command>
    <platform>neogeocd</platform>
    <theme>neogeocd</theme>
  </system>

Hope this helps someone.

Hey im trying to run it .with
lr-neocd
but its just going back to ES
any ideas ?

Darksavior

@shavecat Enable verbose logging and post the log.

Darksavior

@shavecat You need to post the contents of runcommand.log with verbose logging enabled.

shavecat

@Darksavior
how do i do that ?

@Darksavior
That is what i wrote already -0

That's not a Verbose log. Enable verbose logging and then look into the log to see the error. Post it on pastebin.com.

@mitu
"When launching Libretro cores (those prefixed by lr-) the Runcommand launch menu presents the option to Launch with verbose logging. This outputs more information to the log file found in /dev/shm/runcommand.log which is useful, and often necessary, when diagnosing problems. Once the game is exited, the log file can be downloaded via SFTP or viewed directly via the command line.

Again, this is not a verbose log.

@mitu
Hey again
so how do i do that ?
there is no explain ...

mitu

I think it's described pretty well in the docs - in the link posted by me or other posters. Just start the game by choosing the 'Launch with verbose logging' from the runcommand launch menu.

@mitu

so im using the lr-neocd
and its loading but i just getting a black screen

Either a bad .chd file or missing BIOS files - which should match what's described in https://github.com/libretro/neocd_libretro. Your SYSTEM folder is borked though, instead of pointing to the BIOS folder as it's configured in RetroPie, it points to the ROMs folder - you probably reset the RetroArch's configuration file or messed up the configuration when you created a separate system for NeoGeto CD.

@mitu
Okay thanks
i will check it out :))
can i uninstall and install retrorach and it will fix it ?

No, that's not how it works.
