@MajorDangerNine It's not an official libretro core for legal reasons. https://github.com/fabrice-martinez/neocd_libretro/issues/1
If you can figure out how to make samsho3 not freeze up, then please post an updated binary, thanks.

@akafox
-march=nativeis not supported by thegcccompiler on the Pi (hence the crash). You can take a look at the compilation flags used by the RetroPie-Setup script for various platforms here.I am not using the retropie-set up script. I am just ssh in and compiling
-
I just compiled it on my own, yay. The default options @MajorDangerNine provided works but I also tried on my pi3b+:
set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -march=armv8-a+crc -mtune=cortex-a53 ${BASE_CXX_OPTIONS}")@akafox Maybe upgrade to stretch? My setup is always up-to date.

Hi.
Someone can do me a favor and compile it to run on a retropie lubuntu install? I am a total noob on do that.
Thxs. -
@wmarcio compile it to run on ulbuntu? it would be the same as any other compile build. Makes no difference I would think except for maybe needing a lot of dependencies. However are you asking if it can be done (I assume yes) or are you asking for the compiled core? I doubt anyone here will share the core..for various reasons.
@ Darksavior THANK YOU! for that cmake line! I thought the RPi3 was arm7..guess I was wrong? Anyway I got it working! Works great. I did have to upgrade to stretch (retropie 4.4) my "main" sd card is on the old jessie because I am working on a project. I used the card out of my RPi1 (yes a raspberry pi 1) and just had to install some dependencies and it worked great. (No I put the card in my RPi3 and compiled it..yes I know it will not work with the pi1..)
So my question here is why use the "Generic x64 options" to compile and not the "All architectures, optimized for the machine NeoCD is compiled on" line?
Just curious that is all!So I set it up as a system in Retropie and it works from the GUI just like everything else does. Where does the .info file go? (I can't find them anywhere.) Now we just need a NEOGEO CD Theme for Retropie. (Hint!) Again thanks..cheers! :D
Edit: I compiled using the "All architectures..." line. No errors compiled fine.
Have not had the chance to "test the difference" I will report back when i can.So I can not tell a difference and yes samsho3 still locks up my pi no matter which one i use -
I reported the problem with samsho3 and it got fixed rather quickly. I can verify it works now.

Now if only either added CHD support
A bounty is open about it, feel free to back it : https://www.bountysource.com/issues/70116022-request-chd-support-for-neo-geo-cd

@barbudreadmon Nice. Thanks for informing me about this. Still, I'd probably be more inclined to donate to the PSX one.
https://www.bountysource.com/issues/57712065
Just a personal preference. PSX is probably one of my favorite systems, while Neo Geo CD is a novelty to me at best.
-
@MajorDangerNine No problem :), i was just informing you about this.
-
Can anyone tell me a way to make it so I can edit the "opt" folder to add the "lr-neocd" folder,
I tried following the info in the text file, by changing the password so I can use WinSCP, but it still says "permission denied".
Any ideas? or know an easy way I can get it working?
-
@Winklepicker You need to enable the root account and log in with that. It's how I do it.

Can you tell me what I would need to do? I've tried to follow tutorials on youtube, but never seem to work.
If you could tell me the method how you did it, would be great.

There is nothing in that discussion to suggest that it can't be ported to libretro for legal or other reasons. The way I read it is that the developer would like it to happen but if working on other things at the moment. Maybe a bounty would help!

Thanks for the info, I got it working and its really fantastic. The CD soundtrack is absolutely fantastic for these games.
A bug:
I noticed though is when a game is loaded, normally the Neogeo CD console would dislpay a "Now loading" screen.It does display the short loading screen for about 1 second, but its cut in half.
Its not a big deal tbh, and does not effect gameplay. But I thought I would mention it anyway, thank you for again for adding this wonderful emulator.
-
@Winklepicker it's most likely related to your choice of bios/iso for the neocd emulator, i'm unable to reproduce this on my side. If this issue is bothering you, you can also try running those ngcd games with fbalpha.

Thanks for letting me know about that. Your right its probably a version of the bios or images.
I checked the bios I am using and its called "neocd_z.rom". I did have a massive problem trying to locate a neogeo cd bios.
Also the images of the games I'm running are "Img" and "cue" files, via a "TruRip" set.
it really isnt a big deal with the image cut in half. Its just something I noticed when I was playing some of the games. But thought I would mention it here for future documentation etc.

Sadly that was not enough informations for me to reproduce it :
- Which version of kof95 iso were you running ? The TRURIP ngcd isoset has 4 of them (2 revisions of the game x 2 localizations)
- Having the hashes of all your bioses in the bios/neocd folder would help
- What about core options ?
While it's not a big deal, it's always better to fix an issue when it is found, however we first need to be able to reproduce it
-
@Winklepicker I get the artwork cut off as well. I really don't care. Due to the fast loading hacks, I see it for like a second. I'm using some img/cue rip with the cdz bios.
You can report the issue to the dev's github so he can take a look at the problem.
