@SeeNoWeevil Yeah, arcade roms are a headache and you are correct, you have extracted roms, but don’t know what version of MAME they are for. It’s just as bad as finding a random arcade rom on the internet and hoping it works.
But there is good news, most neo geo roms have not been changed in years as they were ripped very well early on. So your best bet is try to run them on Finalburn neo and see if they work. If not, try MAME 2003. You will also need a neogeo bios file put into the bios folder. Which is just as illegal as downloading a rom. Or if you're lucky, the makers of these machines and gog may have put it into each rom or have a copy somewhere that you can extract it.
It didn't, that bios with crc 0x91b64be3 has been part of the neogeo romset for 2 decades, it's the default neogeo bios (MVS Asia/Europe ver. 6), its presence has always been mandatory in a normal neogeo romset. My guess is that you deleted that bios and put another one (AES or unibios) in its stead, it's a known trick to force another bios in some arcade emulators (it's the only way for pifba iirc), FBNeo doesn't accept that trick though because it has proper means to change bios through core options, and it requires that bios to be present as a fallback if the alternate bios you select in core options isn't available.
I don't think anyone is gonna provide that kind of support for several years old version of our project (i certainly won't), so you should use the current version (FBNeo), furthermore that issue is probably something we solved long ago because afaik those games work properly with runahead (which saves and load states at every frame).
@cnoto Cool! I did something similar with the speakers in my cabinet, but I think yours turned out even better. The speaker covers were a good choice.
There are actually several MAME roms that are essentially video pinball machines. The coolest thing about them compared to console or PC pinball titles is that they actually prompt for coins (like any other arcade game) and keep real high-score lists (also like most other arcade games). Some are better than others, FYI. Time Scanner is pretty good, as is Pinball Action, Speed Ball and Grand Cross (which is really unique).
I face indeed the same issue, i recently started using my Pi3B+ again to make a Sega only system, and after a clean install, FBNEO performs really poorly. compared to the FBALPHA it used to run before i stopped using that Pi.
In any event I'll try the suggestions here, and also have a look which version is included by default before i update it.
@mortalwombat i think i would be incline to agree with @mitu that it’s likely an internal button that doesn’t communicate with the OS. my point is that you don’t really need another button for retropie.
EDIT: samsh5fe titlescreen is still 'Samurai Showdown V Special', maybe it's not the 'perfect edition'.
Fullname of samsh5fe is "Samurai Shodown V Special (Final Edition, location test version)", it is indeed what some people refer to as "Perfect Edition". The word "Perfect" feels kinda counterfeit though, afaik they simply removed some gameplay elements from "Samurai Shodown V Special" (probably making the game more casual in the process) to make room for a story mode.
Except if you are using a non-merged romset, you'll probably need its parent samsh5sp.
From what I understand the "Perfect" edition of the game is an emulator that runs the "Special" edition, and overlays it with new content. It isn't a self-contained ROM.
To be more precise, the commercial emulator from "Samurai Shodown Collection" uses some quirks to replace the title screen and to add an english translation to the story mode. FBNeo use the raw romset and doesn't have any of those quirks.
Your bios is all wrong for neocd, you should have a neocd.zip and a neocdz.zip and they should not be in a separate folder. I'll have to check later but they should be in your BIOS directory.
No, as i said, you are trying to launch games for 1 system (neogeo pocket games) with an emulator for another system (lr-neocd, which emulates neogeo cd) while using the bios for a third system (neogeo mvs/aes). You need to decide on 1 system.
If it's for your father, you can never go wrong with neogeo aes/mvs, which was the dream console for anyone from my generation. Neogeo cd was the "cheap" version of that console, and while emulation cancel its main drawback (loading time), the graphics are still inferior to the mvs/aes and the games use more storage, so i don't recommend it. Neogeo pocket was a handheld, and a niche one.
Documentation about neogeo emulation is there : https://retropie.org.uk/docs/Neo-Geo/ . You'll have to read all of it and the linked documentation specific to the emulator you'll chose, otherwise i think you can give up on neogeo emulation.
