NEO-GEO CD for Dummies

mitu

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.

No, that's not how it works.

shavecat

@mitu
didnt think so.
will give it a try with the bios system and chd thanks :)/

Got it working was needed to change in the retroach menu the bios select .
thanks a lot @mitu ! :)

Why isn't neogeo cd in a separate folder from Neogeo by default? Just curious.

simpleethat

@Unknown I believe because it's an extremely recent addition to the package and the latest release for Pi4 is still beta

Darksavior

@Unknown Personal decision I suppose. The same reason why there isn't a tg16/pce-cd system folder. You're free to make them yourself. It's what I did.

Not to mention the fact that the Neo Geo CD catalogue has very few exclusives when compared to the original Neo Geo, I imagine it just makes sense to just put them all together.

Unknown

@Zering Yeah, but it would be simpler than having to select the correct emulator for each cd rom.

Zering

@Unknown You don't have to do that. You separate Neo Geo CD from the rest in your es_systems.cfg and create a retroarch.cfg and emulators.cfg for Neo Geo CD and you're all good.

@dteam , thank you for writing this guide, getting my/any NeoGeo games to work had been something I'd been meaning to figure out.

For a noob tho, can you elaborate though on step 4A, how you got to entering the es_systems.cfg etc part?

Was it in the Main Menu, Options, Retropie Configuration, F4/Command Console, or somewhere else?

I'd tried all the steps you listed before (up until 4A), and when I tried loading any of the NeoGeo games, the CD graphic would show up but the games would never load (I think I tried both lr-fbneo & lr-fbneo-neocd as emulators, but one never worked (I forget which, possibly neocd) never loaded, it kept defaulting to the other.

As is, I'm not sure if it's because I DL'd different/better neocd / neocdz zips that I put into the retropie/BIOS/neocd folder, or if that matters at all, but all of my NeoGeo ROMs-- Burning Fight (NGM-018)(NGH-018), KOTMonsters (Set 1), Magician Lord (NGM-005), Mutation Nation (NGM-014)(NGH-014), Neo Bomberman, Sam Showdown/Sam Spirits (NGM-045) & Sengoku Denshou (NGM-017)(NGH-017) if it matters-- currently seem to be working out of my Arcade folder, running off of lr-mame2003 (fbneo & fbneo-neocd are optional emulators), w/the neoGeo.zip file in the same folder (as I understand you used to need to do).

However, for all I know, a simple update could render them all unworking again (I'm currently using Version 4.7.3, Last Commit 2 days ago, on a RPI4 [armv71 running on Raspian GNU/Linux 10 (buster]). So, I'd like to try your method/see if I could get them working out of the NeoGeo folder (where they also are, but not working) as well.

Guess the other question is, are there any other optional packages/versions of MAME or NeoGeo that could help them work? Because I also put these NG ROMs in the mame-libretro folder,band they didn't work there either.

Sorry for the long post, just didn't know what all info was pertinent. :/

1- Connect your Pi to FileZilla. For es_systems.cfg,you have to copy the one from /etc/emulationstation to /opt/retropie/configs/all/emulationstation Your system now will priorise the one there and you will be able to custumize It , play with systems order and update your Retropie without a reset of your es_systems.cfg file

2 - Convert your rom in .chd. see : https://retropie.org.uk/docs/CHD-files/#creating-chds-from-cd-roms

3 - 4A. (MIX with NEOGEO (easier)) Go in neogeo system in es_systems.cfg
/opt/retropie/configs/all/emulationstation and add .CUE and .cue in <extension> line.

I forgot to mention to also add .chd and .CHD
For option 4A:

   <system>
    <name>neogeo</name>
    <fullname>Neo Geo</fullname>
    <path>/home/pi/RetroPie/roms/neogeo</path>
    <extension>.fba .zip .FBA .ZIP .7z .cue .CUE .chd .CHD</extension>
    <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ neogeo %ROM%</command>
    <platform>neogeo</platform>
    <theme>neogeo</theme>
  </system>

4 - lr-neocd is the good emulator

It should be ok now

For lr-fbneo, you need a specific romset

@dteam appreciate it, but apologies, you're jumping way ahead... I didn't even know what Filezilla was (I had to Google SFTP too; after all your post said this was for dummies!!), nor did I have it installed on my Pi.

Fortunately I was able to use the sudo apt-get install Filezilla prompt on command line, but now, I'm not finding any prompts on how to launch Filezilla on command line on a Pi running Retropie (since you did say connect your Pi to Filezilla), or in general; most links that I've encountered (like this guy) just mention how to launch it on a desktop computer:

I was however able to enable SSH (as other sites have suggested), but that might be irrelevant to this process...

FilleZilla is for Windows. It's an easy way to transfer and manage files in your Pi with your computer. To edit files, you will need Notepad++ on Windows. It's for Dummies, but you need to know some basic stuff. Do some search in the Docs section and in this forum before. You will found a lot of answers to your questions.

MortalWombat

@dteam Well bud, then the plot/guide thickens, as I'm a Mac user... and though it's implied that Filezilla is available for OSX, accordingly to the article below, Notepad++ itself is not (not sure if any of its equivalents would work the same).

I'm still not entirely sure why it's necessary to use 2 desktop/laptop apps to get these NeoGeo roms working? (after the initial formatting of the MicroSD, I've generally just had to use my laptop to download & USB the roms themselves).

Hello, I get an error saying that there is npt config for neogeo_cd what should I do?

@Helm619 Please don't necro post and bump very old topics. If you have a question or an issue, please do so in a separate topic.
