@greenhawk84 yes.

Add the line lr-flycast = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-flycast/flycast_libretro.so </dev/null --config /opt/retropie/configs/arcade/retroarch.cfg %ROM%"

to your /opt/retropie/configs/arcade/emulators.cfg.

Move the rom to the roms/arcade folder.

Restart Emulationstation, click the game name in the arcade list, pull up the runcommand menu, select emulator for ROM, lr-flycast should be in the list, select it, and launch.

I assume you have or know how to set/activate runcommand. if not, go to config menu of emulationstation, select "run command configuration" and make sure "launch menu" is enabled.

@codafire https://retropie.org.uk/docs/MAME/ lists the romset collection used by each MAME emulator.

@jiryn said in Sound Issues with System 32 Games in MAME2003, 2010 and 2016 (Jurassic Park):

@barbudreadmon
Interesting, and I never use the controllers in bluetooth mood, they are always hard wired to the console with USBC
Never tried overclocking, just use it stock for the most part.

More interested in the best em ups anyways, but Jurassic Park was always a fav.

The Sega system 32 graphical rewrite circa MAME97-98 will always cause performance issues on lesser devices,
as @barbudreadmon suggested quite often this can cause skipping and or other sound issues. MAME2003
is one of the fastest cores and apart from that it uses the faster although slightly more imperfect system 32
video code from before the big rewrite i mentioned above.

So it might be your best bet to get the best performance on your device of choice and may sort your sound problems
when playing Jurassic Park it's worth a try at least.

Special kind of stick, for controling movement whilst shooting in another direction (example ikari warrior),

Ah, OK. I learned something here!

"Eierlegende Wollmilchsau"

Hahahahaha! I learned another thing today! Yes, I totally understand.

P.P.S.: Seeing such Wiki Articles now(adays) are somewhat frustrating me: Analog-Stick - sigh...

That article leaves a lot to be desired. Lots of words, and yet says very little that's useful!

I may take another pass at searching for details on the UltraStik 360 + RetroPie, and think more carefully whether it's something I might want to try — or not. Part of me, at this point, wants to just load MAME directly on something like an Intel NUC, running Windows, and call it done. I really only use the arcade functionality of RetroPie, and perhaps another platform would be better suited to what I actually want.

But... The tiny little Raspberry Pi is appealing for many reasons — cost among them — so who knows.

Thanks for replying.

@yfzdude I finally did find it; at least in my RetroPie, it's actually:

Quick Menu -> Overrides -> Save Core Override
Quick Menu -> Overrides -> Save Game Override

Writing this primarily for the benefit of future readers.

Thanks for the help on this. I don't know how I missed it; I would have expected save options on the Main Menu, but I'm sure there's a method to the madness.

@iandaemon that’s how I started, but your luck may vary. I found that most Konami beat em ups (tmnt, simpsons,, X-men) were not changed over the years and most neogeo games have not been changed in years. A lot of my old 2010 roms (actually from 2010)set worked on those particular roms worked with FBneo. And some even worked in mame 2003.

@agtrigormortis Yeah, I have that problem with several games I'd like to have. The 1992 X-Men beat 'em up is a prime example. Apparently I missed the boat for it being on XBox and Google Play. It's too bad companies don't do more collections and ports for those who can't afford to be arcade collector enthusiasts and don't want to be pirates. But on the bright side there are a lot of options for many of the best arcade games in the collections that do exist.

@buzz That has to be it! Thanks so much!

It's funny how our memories distort things over the years, for some reason in my mind the controls were like Tempest. Obviously not!

By the way, MAME 2003-Plus has four different button layout presets for gamepads and arcade sticks. See Default RetroPad Layouts in the Libretro wiki for MAME 2003-Plus. They should cover most games' button layouts.

Just updated a bug in the RetroPie installation script, which did not take into account the move to the new carbon-2021 theme from RetroPie v.4.7.19 and onwards.

Should work now for both newer and older RetroPie versions. Sorry for any inconvenience.

@ronson here at retropie we only support and recommend the images found at https://retropie.org.uk/download/ - there are a number of 4:3 themes available for the default front end 'emulationstation'. see https://retropie.org.uk/docs/Themes/#theme-gallery

maybe someone will reply with specific recommendations possible within retropie.

@mitu That was it! Thank you so much for taking the time to reply on my thread. The internet needs more people like you.

@lazaruz A pi4 is faster to handle the more accurate emulators but it also makes some new games playable. Taito F3 games are now full speed. You can play sega system16/18 games on fbneo without slowdown so I don't need to deal with mame2003's buggy bootlegs. You can use mame2010 or 2016 for bug-free system32 games like golden axe 2 and spiderman. 3d games like tekken, etc are still unplayable. If you can run your favorite games in fbneo now then there's no point using a pi4.

Added pause overlays for Neo Turf Masters. and Windjammers

@dipkid Awesome work!

I have solved it!

It looks like it was the difference between using mame2003_libretro.so and mame2003_plus_libretro.so. I had copied mame2003_libretro.so from the regamebox distribution to the retropie distribution by mistake when I was testing to see if that file was the difference in performance... As can be seen above by my documentation of the command which runs the emulator in regamebox, it uses mame2003_plus_libretro.so.

So, to recap, if you are experiencing the usual slowdowns with double dragon while using retropie distribution and would like to eliminate it, you can just copy mame2003_plus_libretro.so from the regamebox distro into retropie wherever mame2003_libretro.so is... and of course have the settings set to use mame2003_libretro.so. Also, i assume if you install the mame2003_plus core and instruct retropie to use it, the effect would probably be the same.

Hope this helps someone out, I know there is lots of talk about laggy double dragon, and there really is no fix because it is emulating lag which was present in the actual hardware of the arcade cabinet... i've seen posts saying to use the bootleg version (ddragonb.zip) because it was built on better hardware, but this looks like a solid and more appropriate approach to fixing it!

And in the meantime I've tried just about every possible setting in lr-yabasanshiro and Nights is still choppy. It's not far from being playable, but it's not playable currently (much like Panzer Dragoon Saga).

We don't support 3rd party images, especially the ones loaded with ROMs - as are the ones that you're trying to choose from. Use the image from retropie.org.uk/download and follow the installation instructions from the Docs.

If you're hard pressed on time, I recommend you get your brother friend a ready made console, like one of the mini consoles released by Sega/Sony/Nintendo, which come already installed and with the games included.

Disregard. I figured out the issue. I originally downloaded a Romset and it had a Gamelist included. So I guess if a gamelist is already in the rom folder, it ignores the one in config.

Sorry for the inconvenience.
