You might want to try latest version, this is still WIP but some protection have been bypassed.
NB : Just mentioning this, The Last Blade 2 got a lot of graphics removed in the ngcd version, in peculiar i remember seeing screenshots from both version of the “burning” stage.
Edit : i can confirm your issue with both version of the game.
So you’re saying that it happens on both the cracked and non-cracked copies?
Yeah, and apparently this game doesn’t work either in mame.
hi thanks again for the neogeo cd support on fba. I have read that run ahead feature will be compatible but after some test it doesn’t work. is it still in progress ? thanks
Thanks for the report, ngcd is still being worked on actually, but i didn’t know read ahead and rewind were having issues (savestates work though).
ok thanks no worries we will patiently wait for this marvelous feature regards
I’m venturing into NG-CD emulation for the first time. I downloaded some games and all came as a .zip file, which after being extracted presents 1 .iso file, 1 .cue file and several .wav files. When pointing to open the .cue file of any game, the bios screen appears for about 3 seconds and then the Retroarch crash and close.
After reading the posts above I believe it is because of the format of the games that I downloaded. Is it possible to somehow convert the games I already have to the correct format? If so, how could I do this?
I am using Linux Mint 19.1 with retroarch and all cores updated.
ISO is not supported any longer. Google is probably a better source for methods to convert the iso to bin, but honestly it’s likely easier to find the correctly formatted files in this case.
@McCloud @zachmorris As i mentioned previously, “CDmage” is an amazing freeware which allows you to convert ANY iso format to the fba-compatible single file bin/cue, and it is really easy to use :
CDmage is also working perfectly through wine on linux.
@SkyHighGam3r I just pushed the fix for Last Blade 2 on github.
@BarbuDreadMon First of all, thanks for the tip. I was able to convert the .iso file and now the game starts and is perfect playable. But no music plays, just confirmation sounds and characters voices.
Comparing the two .cue files, the first referring to .iso and the second referring to .bin, it is perceived that the problem is in the tracklist.
I simply tried to copy the codes for the tracks from one file to another, but besides not working, it also made the FBA not even open the game.
How should I proceed to make sure the tracks are correctly recognized and played during the game?
Maybe you loaded the .iso file in CDmage ? You must load the .cue file, and you are supposed to see the list of tracks at the left of the window after loading it.
Oh god, you are right. My mistake.
Converted again using the .cue file and now everything is working perfectly.
Thanks a lot for the help.
@BarbuDreadMon Thanks for the Last Blade 2 fix. It works beatifully.
Too bad this core does not support CHD, otherwise I would be using this core for NeoGeoCD emulation instead of mame. Would you be interested on adding support for chd if I open a bounty for it?
Greetings.
barbudreadmon has said that they don’t personally plan to implement CHD support. In my opinion that would be the perfect reason to start a bounty, in order to attract someone else who is willing to.
CHD support has been added to many cores at this point so it’s quite possible another coder will become interested. What we do know from this thread is that FB Alpha’s maintainer has repeatedly asked to stop being asked this question. 
If you start an issue on github hopefully it can also move discussion of CHD to a more appropriate location. Please feel free to tag me in the issue as I’ll also help try to attract attention to it.
@cubatilles @markwkidd There is already an issue opened about this : https://github.com/libretro/fbalpha/issues/143
Feel free to open a bounty about it, again i’m not against chd support (i won’t implement this myself though, i’m not interested and i think some developpers are more familiar with the format than me), as long as it doesn’t break anything.
@cubatilles I put five dollars on the existing issue to start a new bounty here: https://www.bountysource.com/issues/70116022-request-chd-support-for-neo-geo-cd
Thanks @markwkidd. I’ve just put 5$ more. Let’s hope more people is interested and we get a good bounty.
how i wished that CHD support can be a frontend feature instead… which means retroarch should be able to open any CHD (cd image at least), unpack in in memory and then run some sort of callback to fetch the unpacked tracks/cue. this could benefit any core that uses cue-based cd images converted to chd. of course this would mean more memory footprint and old, small memory devices will be affected. (thats why its just a wish)
I guess in theory it should be possible. I would donate if someone opens a bounty.
How do these bounties work? Like does it only withdraw funds if it’s completed or something? I’m def interested in supporting it though, would make my life much easier to use FBA like I do with AES games than with MAME (god I hate MAME…) since my CD and AES games are all in the same wheel on HyperSpin.
Haven’t had a chance to sit down and extract my LB2 copy to try the fix as of yet, but it sounds like it’s working for multiple folks, and I really really appreciate that. I was very interested in playing this (possibly more than any other NGCD game) on the CD format.
