SNK Neo Geo CD Using FBAlpha Core in Retroarch

[tallpr24]

when i try to load .cue file i  retro arch give an error"could no load content"

[DOS76]

I don't use that core or emulate Neo Geo CD through RetroArch so I don't know. I use MAME personally so I can't really help with the nuts and bolts of it. I just know if it doesn't work in RetroArch it won't work in LaunchBox.

According to the docs, it only supports single file bin/cue images.  Yours may have multiple files.

https://github.com/libretro/FBNeo/blob/master/src/burner/libretro/README.md

Neogeo CD doesn't work, why ?

There are several things to know :

• You need a copy of neocdz.zip and neogeo.zip in your libretro system directory
• You need to add --subsystem neocd to the command line
• Supported format are ccd/sub/img iso (trurip), and single file MODE1/2352 bin/cue (use utilities like "CDmage" to convert your iso if needed)

 

Or try switching to the NeoCD core or MAME.  I use NeoCD because it can skip CD loading.

does it support CHDs? If so you can download them from Pleasuredome as part of the software list chds you can just download that section assuming your torrent client is setup to allow you to pick what you download before the torrent starts

NeoCD does.  I made CHD's from my bin/cues.  Saves a ton of space.

[tallpr24]

so i have tried mame and a few others with no luck.  but..

my games are in .zip format.  when i unzip them they have .cue, .bin and a bunch other tracks on them.  maybe like you said, the rom is in the wrong format?

[tallpr24]

i just tried all 3 cores and tried to launch the .ccd but got the error in retro arch.

[DOS76]

I would suggest just getting the chd files for these. They will definitely work and also be the best value for space on disk.

[tallpr24]

so just search for neo geo cd roms in chd format ?

[DOS76]

You can get them from PleasureDome they are part of the softwarelist chd set. You don't have to download the whole torrent you can just get the neo geo chd section of the torrent. I already mentioned all this information 5 post up.

[tallpr24]

ok, will try one from pleasuredome and report back.

 

[tallpr24]

damn, it says im shitlisted.  not sure why. i think i only downloaded 1 torrent and seeded the crap out of it for days.  trying to figure out how get my self removed.

[tallpr24]

I gave up, since i only need the neo geo cd exclusives , I ended up only using the following games and just pointing launchbox to mame.  every single neo geo cd rom i thew at it played.  My roms were also zipped and mame played them from launchbox with no issues, and with sound.  I really wanted it with retroarch but for the 8 games i needed it for is not worth the trouble for me at least.

Anyone figure how get SNK Neo Geo AES to work thanks

[sundogak]

@mohanned85

Assuming you have all the proper bios zip files within the Retroarch\system\fbneo directory:

1. Setup in RA with the fbneo_libretro core with SNK Neo Geo AES platform. 
2. Within RA and the fbneo core selected, select Quick Menu, Options
3. Change "Neo-Geo mode" to "Use AES Bios".
4. As example, using King of Fighters 2001 AES ROM (kof2001h.zip) it should then launch the game using the AES platform

 

[mohanned85]

thank you i forgot to change to AES Bios

I'm just trying to get Neo Geo CD to work with Retro Arch,  

found this little guide: https://forums.libretro.com/t/guide-play-neo-geo-cd-games-using-fbneo/17735

got my Bios files in place and they seem to work (not the file sizes you posted though),
thanks for posting the command line thingy for LaunchBox, that did the trick.  

Now i only got one problem, the REDUMP set is .cue and multiple .bin files. 
There is only one game in the entire set that has only one .bin file and that is Puzzle-Bobble (a.k.a. Bust-a-Move).
Puzzle Bobble works fine in both cores, fbneo and neocd  
all other games just load the bios and show like a CD Player interface thing (some of them even play a music track, but only one like the emulator just uses the last .bin file in the zip ...weird!)  

So, i guess they are serious about the 1 bin file support,  
always annoying when the people making the .dats / roms and the people making emulators are not working with the same file architecture in mind.  
converting them to single .bin files (still need to figure out how to do that) of course kills the ability to keep the Redump set up-to-date with new .dat files in the future unless i keep both sets,
effectively doubling the file size of 42GB, it ain't that big of a system but... eh... inconvenient to say the least.

The SNK - Neo Geo CD (NeoCD) RA core supports mutl-bin/cue files and CHD. I tried it with ASO II - The Last Guardians with 24 bin files loading via cue file, and it loaded fine.  I use NeoCD core for this platform since I prefer to use CHD format files.  The FB Neo core  doesn't support CHD files and as you noticed mult-bin files at the moment.  It looks like they are working on the cue/bin side, but not likely support with CHD based on thread I saw.  A full MAME software list set for NeoCD is ~30 gigs, so one advantage of CHD format compression.

I highly recommend you guys to use the latest RA mame core to play ngcd as is considered the best emulator for it and allows to fasten the loading time. I made a guide in the following thread, enjoy and thank me later (it is in my last post on that thread): 

 

Enjoy!

Hey , first of all it takes me a weak to learn more and more about Neo Geo CD but now i almost know to fix all of problems

stop using fba core it's out of date , and start using fbneo core , there is 2 core work with neogeo cd roms which is neocd core and fbneo , iam on linux so i use emulationstation as a front end but it's the same

for fbneo core your commend is

retroarch -f -L ~/.config/retroarch/cores/fbneo_libretro.so --subsystem neocd %ROM%

need bios files and where to put theme

The BIOS files are often found named something else, It must be renamed when placed in the BIOS folder. lr-fbneo has support for the Neo Geo CD system but you will also need the corresponding BIOS from the MAME romset. Prefer to use the UNIVERSE BIOS/UNIBIOS - an advanced Neo Geo bios that allows region selection, cheats, dip-switch control, and more.
        
        Samples should be put under SYSTEM_DIRECTORY/fbneo/samples.
        hiscore.dat should be put under SYSTEM_DIRECTORY/fbneo/.
        Place your BIOS files in "~/.config/retroarch/system/fbneo/".

       roms files should be unziped "it's my problem right now and I am trying to find a solution so if anyone know how to make a retro-arch not load the full zip file but browse the archive then choose the .cue file using commend line please inform me , i can do it using gui but not the commend line

for Neocd core here's is the commend "I'm on linux so change my core and rom paths to suit your install"

retroarch -f -L ~/.config/retroarch/cores/neocd_libretro.so %ROM%

To function NeoCD need a BIOS from a Front Loading, Top Loading or CDZ machine. The BIOS files should be installed in a neocd folder under RetroArch's system folder.
        Place your BIOS files in "~/.config/retroarch/system/neocd/".       

 Need one in the following table

        Filename                Description                 SHA1SUM
        neocd/ng-lo.rom         Y Zoom ROM                  2b1c719531dac9bb503f22644e6e4236b91e7cfc

        You need at least one in the following table. If several BIOSes are available, it will be possible to choose which to run in the Core Options Menu. The files will be automatically byte swapped if needed.

all of your bios files should be named like how i name my bios files , you should be sure that you are pick the right rom set and all roms should be unziped ".cue .bin " or chd 

if u know how could i make retroarch not load the full zip file  but browes it and auto pick the .cue file then using commend line it will fix my last problem , I can do that using GUI but i need to know the commend line for it , so please replay to my comment if you know how or if you have any problem .
