Well that was a nuclear option, but i guess if it worked.

Just only import those to start. Just go to your PS1 folder and put *.cue in the explorer window search, highlite all the results and drag and drop them onto Launchbox to start the import wizard.

Never unzip MAME roms, they MUST remain zipped.

Oh, this is a easy one. Your roms are zipped, but you don't have Launchbox extracting them before passing them to the emulator. Check that box in your first image to "Extarct Rom Archives Before Running". I will add though, there is zero reason to keep roms that small zipped in the first place, you are saving no space, personally i wouldnt keep them zipped, but it's up to you at the end of the day.

I'm afraid that would be virtually impossible, obviously save/states are handled by the emulators themselves, and they all store them in different locations and use different filetypes. So that would mean the devs having to download and setup every emulator ever released and figure out the save paths, as well as the formats used, not to mention save/states often are not actually named the same as the rom, so are impossible to identify. Then when a emulator changes something like path structure, or the format of the saves that all has to be done again. It's really is a lot of work when the emulator itself will just load a save if you have one and choose load save in the emulator.

OK three things, can i see a image of the "Details" tab from your above image, and could you also right click a NES game in Launchbox and go to Edit/launching tab and grab a image of that, and finally on the same edit screen as above please take a shot of the Emulation tab,

Tools/Options/Intergrations/Emumovies.

There is no wiki, and i did tell you exactly what you need to do in my previous post, just go to the screen i specified and edit to your needs. This is the "associated Platform" list i mentioned, as you can see it lists a ton of platforms, if you want to use a Retroarch core for a system that system must be in this list. Then secondly, once you have selected a system, or added a new one by entering it in the empty cell at the bottom of the list, you then need to specify the Retroarch core that system should use, you do that by double clicking the core cell and picking the core you want from the dropdown that opens.

Have you told MAME itself the rompath?

You need to specify which cores you want to use for each platform, we have some of the more popular ones pre applied, but we cant be mind readers and predict what core you are going to use. To specify the correct core head to Tools/Manage Emulators/Retroarch and click on the "Associated Platforms" tab, this will list systems as well as the core they will use, fill free to edit/add any systems and specify the correct core. The system name here must EXACTLY match what you called the system when you imported it, and MAME/Arcade isnt in that list at all by default.

Also unless its a non-merged romset you cant just pull games out like that.

You should never be unzipping MAME roms, so turn that option off.

If you do not have a pleasuredome account in order to get the latest set then i suggest getting the MAME 2003 reference set and use the mame 2003 plus core, it's easy to find that on the internet archive. Although it sounds like a old set its actually relatively new, its using the roms that were around in 2003, but updated so they are modern.

Its also worth noting that the Android version of Retroarch does not have exactly the same cores as the Windows version, so that core just may not be available here on Android.

State files are usually only usable in the emulator they were created in.

This is because you were using a pirated license I'm afraid. Please purchase a legitimate license to continue using premium features.

That would likely mean that no Capcom or NeoGeo games would work im afraid, all those roms have changed since 2012, this is why versions matter. Capcom roms had the qsound file changed at around version 0.184 if i recall correctly, so if your romset is from after 0.184 then you will HAVE to use a emulator version that was released after that change (early 2017 if i recall) so those roms will no longer work with any version of the emulator prior to that as the files in the zip are now different, and the emulator itself knows EXACTLY what files should be in the zip, if those differ it will not load the rom. Essentially if using a romset from 0.184 or after, then you cannot use any version of MAME from before that version, and 2012 is obviously much before early 2017.

Then your roms are the wrong version for the emulator. MAME is very easy to use, but you have to match your romset version to the same emulator version you can not pick random roms from around the internet from all different romset versions and expect them to work, thats just not the way MAME works i'm afraid. If you want to make sure that they work, get the latest MAME romset (currently 0.235) and use the core in Retroarch simply called MAME (this is always current, but may still be 0.234 as 0.235 is very new still). Or you can get the specific MAME 2003 romset and use the MAME 2003 core in Retroarch.

First results with a quick google.

Which is a little awkward, its not a mame 2003 romset, but its also not a current romset (its over a year old, i would guess that "most" games would work, but you may have issues with some if using the wrong version of the emulator, which you will be if using retroarch.

You can also set a exit controller combo directly in retroarch, Settings/Input/Hotkeys.

That also actually sounds like a bios file, there are hundreds of those for all different cabinets, so they are very important.

All needed files are in the MAME fullset downloads. So either you are using the wrong version of the emulator for your romset, or you downloaded a random rom from the internet and are using the incorrect version of the emulator for it. Also we cannot share those files even if somebody had them as they are covered under copywrite.

Well the same is true for no filler lists, its the opinion of the person making the list only, so may be completely useless to someone other than the list creator.

Only you are you, so any list is gonna be based on someone else's tastes, so may have games in it you don't care for, or missing a series you do like, its very subjective, so there is no "good games" list for that. Personally i have 47 CHD files, i havent run into any games that i was missing it, and i do also have some for games that i probably wont ever play like the Area 51 games (i dont have a lightgun), i just made sure i had any street fighter and killer instinct CHD's, and all the CPS 3 CHD's i saw, as well as others that i recognised the names of, and a good portion of them are actually Naomi games, that i dont actually emulate anyway.
