NEO-GEO CD for Dummies

Nakynaw

@mitu I was about to delete my last post, cause it works! But since you answered so fast, I'll leave it there. Maybe one day another newbie will need this.

IDK why the command line to create a CHD per file did not work, but the batch chd creation command of @Clyde worked now that I have moved all the game files directly in "neogeo" and not in sub-folder!

Thanks guys. Now, I just have to let the computer do is job and wait.

I was about to start my playstation and dreamcast library (only did Atari, NES, SNES and Sega so far), so I guess now I'll know how to have a neat list of CD games with proper art and info! :)

BTW, should I keep the "CDZ patched" version or the normal version of those games?

Nakynaw

Hahaha, my joy will have been of short duration... I succeeded in creating CHD files, my games are all there and the list is neat... But now they do not load... I think I have the same problem as @zerojay : with lr-neocd it does not boot at all, with lr-fbneo-neocd it shows the CD image of the intro, but crashes right away.

When I compressed the .cue files to .chd I noticed that the PI had created a subfolder "fbneo" with the "neocdz.sf" file in each game's folder... So, I figure I would leave at least one "fbneo" folder there in "neogeo" folder. Was that right?

Here is what the Verbose logging said for lr-fbneo-neocd :

/opt/retropie/supplementary/runcommand/runcommand.sh: line 1264: 6464 Segmentation fault /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-fbneo/fbneo_libretro.so --subsystem neocd --config /opt/retropie/configs/neogeo/retroarch.cfg "/home/pi/RetroPie/roms/neogeo/Aero Fighters 2 (Wld).chd" --verbose --appendconfig /dev/shm/retroarch.cfg

Anyone understands the problem? Would it help if I paste.bin the entire log?

@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.

Just for the sake of completeness:

@Nakynaw said in NEO-GEO CD for Dummies:

Indeed, it returned "0" for an answer. But I do not get it. I do have ".cue" in neogeo rom folder...

No, you had them in subdirectories of the neogeo rom directory. My command line only works with files in the current directory. It could be expanded to "walk" through any subdirs, but since you fixed it another way by now, no need for that.

I tried this :

pi@retropie:~ $ chdman created -i "Metal Slug 2 (Wld).cue" -o "Metal Slug 2.chd"

But it said "command not found" and I had just installed mame-tools and rebooted.

It's createcd, not created. 🧐

I know, I am so far from knowledgeable in the Pi district. :/

Nobody was born with this knowledge. We all learn on the way.

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

zerojay

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 ?

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

shavecat

@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.

What im doing worng ???

I did got it runging with the fbeno-neocd
but its getting to the disc loding screen and quit

Again, this is not a verbose log.

shavecat

@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.
