Neogeo

The Neo Geo page in the wiki could use some updates to make this process clearer: https://github.com/RetroPie/RetroPie-Setup/wiki/Neo-Geo

The 'managing ROMs' page [ https://github.com/RetroPie/RetroPie-Setup/wiki/Managing-ROMs ] has been updated recently, which may provide some source material for the Neo Geo update if any intrepid user would like to give it a shot

I don't have a RetroPie setup or I would be more tempted to take this project on myself.

@markwkidd Personally I think it is as clear as it could be. What is missing? Which steps?

columboscoat

@markwkidd You don't use RetroPie? You just like to hangout on RetroPie forums... why?

Use google and search for romset 0.2.97.39
Put all the roms (in zip format) you want into the fba roms folder.
Also search for a neogeo.zip bios and add that one too inside the fba roms folder.

Please read the romset section of the RetroPie wiki which explains stuff about the parent roms.
If you see 3-4 roms with the same name but they say EURO, US or Japan at the end of it then usually the largest one in file size should be the parent rom.
And also read quickly the stuff about the neogeo bios (UNIBIOS) which will allow you to do various game settings like blood for Metal Slug or Samurai Showdown.

Setup your controller(s) for the fba emulator.

Done!

@columboscoat he does lots of good work for gamelists and other stuff with retroarch/lakka so it's directly related to all the stuff he already works on.

columboscoat

@herb_fargus Just wondering. 'Cos my brain works that way. I'm sure, like all men, he appreciates you answering for him...

columboscoat

@FlyingTomahawk I don't think he's getting the parent/clone dependency thing. Most people don't until it is explained. I tried but I'm no expert.

i am currently running Rpi3 retropie v 4.1.10 im using Ir-fbalpha says it uses (0.2.97.39) these are the roms and bios i am using however anytime i try to load up a game it just goes back to game list im at a loss here been trying to get this to work for like 2 days!

ok, you don't need mame 0.78 to run neogeo. you have a correct set, so it's just a matter of getting it all in the right place.

to get neogeo to work, you will need to take the following two files from your 0.2.97.39 set:
neogeo.zip
mslug.zip (a neogeo game, just to test)
and put them in the neogeo folder on your pi.

does this at least work?

columboscoat

@dankcushions yeah, but he is trying to run single games on fba using a 0.2.97.39 romset. I have only ever read advice here, from you and others that ONLY a full set is good enough. Obviously a neo-geo ROM plus the BIOS from that set will work. I just think you are sending him down a blind alley. What happens when he tries to use a ROM that is a clone and requires a parent from the same set?

@columboscoat ?

well, neogeo is the subject. the fba romset floating around is merged anyway (so only has parents as far as fbalpha is concerned).

i don't think it's necessary to explain mame to run neogeo.

columboscoat

@dankcushions You're probably right. Plus he is trying to use lr-fbalpha. He has the correct BIOS and it's all good to go... or should be at least. You're the expert, I'll defer to you.

Fbalpha works with merged sets. I think every neogeo game have the same parent anyway (which is neogeo.zip). If both its rom and its neogeo.zip file are good, then it's a setup issue. By the way, neogeo.zip file go in the rom folder, not in the bios folder.

Try to run lr-fbalpha from bash. You'll see what errors You have there. Then it'll be easier to solve it.

I know that you are well versed on how FBA works, so can I use a specific example to ask?

The OP said they were interested in the "SNK vs Marvel" titles. Picking one arbitrarily I wound up with "SNK vs. Capcom - SVC Chaos Plus (bootleg set 2) [Bootleg]" The DAT says that this title has a parent ROM: "svc"

Here's the relevant section of the DAT:
<game name="svcplusa" cloneof="svc" romof="svc">
<description>SNK vs. Capcom - SVC Chaos Plus (bootleg set 2) [Bootleg]</description>

How would the OP make sure that this NeoGeo clone plays correctly with a merged set?

barbudreadmon

@markwkidd my bad, i meant a non-merged set, here are the differences :

merged set contains all the files from parent + clones into the parent file, in your example, that would mean svcplusa files would be inside the svc file, let's say you have a directory MY_DIRECTORY containing 2 files (neogeo.zip + svc.zip), you could launch svcplusa by running "retroarch fbalpha_libretro.so MY_DIRECTORY/svcplusa" (yes, without the extension, because the file doesn't exist)
non-merged set : all the necessary files for the game are inside the file for the game, in your example, that would mean svcplusa.zip would contain the files it needs from its parent svc.zip (in this case, it would need svc-c1.bin to svc-c8.bin, svc-m1.bin, svc-v1.bin to svc-v4.bin from its parent svc.zip + its own files specific to this clone which are svc-s1pl.bin, svc-p1pl.bin and svc-p2pl.bin)
split set : each clone contains only its own specific files, so it will search its parent for the additional files

Basically, what's happening when you load svcplusa (with or without the extension) in fba/mame :

The emulator match the name with a list, and retrieve the list of files needed to run the game
It will then search for those files in the file named svcplusa.zip, if the file doesn't exist or miss a few files, it will then search in the parent svc.zip, if the file doesn't exist or it still miss a few files, the loading of the game will fail.

Which means, as long as you have all the files needed, and all of them are in clone.zip and/or parent.zip, the game will load.
Of course, it applies to any game.
I hope it cleared up things.

markwkidd

@barbudreadmon Thanks!

It seems like FB Alpha has a more sophisticated approach to loading Merged ROMs than the libretro MAME cores that I'm familiar with.

That helps me understand much better.

barbudreadmon

I just checked, you can run merged set with the extension too, the emulator just doesn't care if the zip file exist or not, also i think i messed up when listing the files from svc/svcplusa, but you understood the general idea.

Sorry to resurrect this thread but I didn't see the point in starting a new one - I'm having similar problems; usin fba for arcade roms (acquired via READ THE FORUM RULES!) and used the neogeo bios from said site but it doesn't work. I tried placing the bios and roms in the neogeo folder but they still don't work, yet other fba roms are fine (including tatsujin II, which makes me a happy man).

If I were to use mame .78 roms and bios in the neogeo folder, would this work? I'm itching to play viewpoint and my son loves king of the monsters so it'd be great if I can get the neogeo games working. Of course I own all said games etc etc.

Thanks in advance

@guythp If you've bothered to read this old thread, you'll know you need the correct romset. Read the links people have posted. You can't just go get random arcade roms and stick them in and expect them to work.

The reason other fba roms work is because they aren't neogeo roms. Neogeo bios is for neogeo games. Games that don't change their romset will work on newer versions. You can find out with hours of trial and error...or get the right romset instead.

If you have the correct romset for fba, it will work. Same goes for mame.
