After a bunch of messing around, I have been able to get everything working so far except NeoGeo.

If I launch a Neogeo game through Retroarch Plus using the FBNeo core, it works no problem. But it's when I try to run Neogeo games through launchbox that I will get a message on screen (seemingly through retroarch as my bezels show etc) stating something along the lines of "rom files such and such...missing etc" or even a black screen.

Things I have tried:

-Moved Launchbox folder to internal storage from my external HDD where it defaulted itself.

-Deleted everything and re-scanned about 3 times over.

-Tried all the various core options from within Launchbox when trying to run Neogeo games.

-Tried replacing bios files within the Retroarch system folder.

 

Again, it's very odd as the rom files themselves are perfectly fine as they run through Retroarch Plus natively. 

 

I am only using Retroarch Plus 64bit version from the playstore, no other emulators etc.

Well no...Still looking for possible solutions as to why it isn't working.

Kind of outta ideas over here.

Is Retroarch plus the version on the play store? Cause that may be the issue, have you tried sideloading the Retroarch from there official site? I remember they had to change things recently due to google, so i'd try with the actual normal Retroarch from there website, as it may be a issue related to that specific version you are using.

It's from the playstore. I wanted simplicity and updates etc.

 

Again though, the thing is that the games work fine using FBNeo core in Retroarch. 

The problem is through LB, as something is preventing it from working. Same rom files, same core, no worky...

 

So I guess what you are saying is that it's some sort of LB and playstore Retroarch plus compatibility issue in regard to Neogeo? Or more specifically FBNeo core?

I would prob rather wait for a future update of Launchbox and just play Neogeo games through Retroarch natively while crossing my fingers that it gets fixed eventually.

I am 42 and I only consider everything up until dreamcast/saturn/ps1/N64 to be retro, and Retroarch Plus from the playstore runs all of that on my Nvidia Shield perfectly fine.

I may dig around a bit more to try to fix it, but I am pretty sure it's got to be something goofy, most likely to do with the google barriers.

Yeah thats why i say try the normal version, its possible that the play store version has limitations that stop other apps giving it instructions, which is what a Frontend like Launchbox is doing. Opening a rom from inside Retroarch is a very different thing than a external program telling Retroarch to start, and with a specific core, and a path to a rom file. Do other systems work, and its just NeoGeo? Also you dont have Launchbox unzipping the roms do you?

All my other systems work just great so far.

Everything from Coleco to Ps1.

Initially Arcade was giving me issues but I resolved it.

Neogeo is the stubborn one here.

I initially allowed the files to unzip etc before realizing that was not the thing to do, so I reinstalled and started from scratch after moving my Launchbox folder to internal storage (to help with menu scrolling/crashes from slowdown).

 

Come to think of it, the "google issue" can't be related...Otherwise my other systems wouldn't work right? Especially Arcade.

So perhaps something to be looked into by development?

That...or I am the only one with this issue and it is something ridiculously small that I have been overlooking?

Update:

After re-scanning the NeoGeo library, I was promted with a request to download Retroarch. This lead me to assume that the FBNeo core within the Launchbox selection is default set to launch from within Retroarch 32bit.

Tested afterward through Launchbox and most titles eventually worked through Launchbox>Retroarch>FBNeo, not Launchbox>Retroach Plus>FBNeo (even though Retroarch Plus > FBNeo works just fine). Possibly something to be addressed in a future update?

I suppose my focus is more narrow than most, as I stick to Retroarch and Retroarch Plus for my emulator platforms. I did this so that my "Bezel project" program continues to work while within LaunchBox.

Update 3:

Seems that I was able to get Neogeo to work within Launchbox by scanning the Neogeo game library through the Arcade category...

 

I can play my Neogeo games through the Arcade selection in Launchbox by selecting the FBNeo core from within Arcade to run them. They also work on Mame_current but with terrible audio stutters.

So I lose my ability to have my Neogeo games nicely organized on their own, but really Neogeo games are arcade games anyway so meh.

I guess it is not much of an issue anymore.

So it's as "resolved" as it's going to get for me.
