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!

@raspberrycoulis i think almost every game exhibits some kind of visual bug with the speed hack on, hence the note in: https://retropie.org.uk/docs/Playstation-1/#video-double-internal-resolution - actually even without the speedhack some games can break with double resolution (doom is an example)

a blacklist for the games that are unplayable with it on is not a bad idea - could be implemented in a similar way to mupen64plus.sh

@Weatherby said in Pi4 default resolution won't work:

The Pi3 runs smoothly at 4k though, it just gets hot as hell.

Pi3 doesn't support 4k, it's probably choosing 1080p as the best display resolution.

I am not sure what the deal is with the audio not working on the HDMI1 port

That's the default. You can switch it from the Audio menu.

@mitu said in N64 emulator doesn't save any settings:

you need to save a game or core override after you've changed the parameters

Can you please tell me where I can find the Overrides-menu? Or which solution would be the best?
When I switch the "Use Global Core Options File" to OFF, then I still the the same problem.

Did you try changing it in the Core Options ? Open the RGUI with Hotkey + X and use the Options menu to change the setting.

Answered my own question. So my workstation has 3 monitors and a TV, the pi had this issue with the TV and one of them monitors. Works absolutely fine on the other 2 monitors though, and the TV in my living room where this was going to go anyways works fine with it as well.

Anyone know why this issue is occurring?

Hey dank, thanks for the heads up; I kinda figured they would be, yeah. I'm just using them as a basis to create my own such that the screen gets positioned right, ie. for the x and y values. I certainly wasn't gonna just lump them all in there.

While I'm here, did Naomi get borked in the last few weeks? Suddenly the ROMs I have for that don't work (since I had to reimage I mean).

You know what, never mind, forgetting so many things already done several times over: BIOS!

@VictimRLSH That worked! Thank you very much for the help

@mitu Sorry for the late reply, gave both of these a shot and it still displayed a black screen on the RaspiConfig

I also just tried group 63 for 1080P with 120HZ and got the same result

@neurocrash Nevermind, it was supposed to be opened with the Hotkey+X button, but on the diagrams for controller buttons reverse the X and Y keys, so I had them mapped backwards.

@mitu Can do! New to the forums and still figuring out preferred practices. Thank you!

Ok. Cannot be done :)
Thanks for your reply.

@_robert1243 Are you a spam bot ? None of your replies have anything RetroPie related or offer any substantial insight into the topics opened by the users.

Afair RetroArch added a new aspect ratio, which caused some IDs to change due to the ordering. So you would need to edit existing configs or reconfigure.

Arcade big joystick or small controller joystick. If you have a big one then dpad. If you have a little one then right stick/left stick.

@BJRetro said in New to this, need help!:

@drevil2002 yeah you should have a dedicated start and select button. Makes it much easier for people to use when they know how to put a coin in and how to start the game.

I second that, although without the currency symbols that I fail to add to the yellow coin buttons on my own DIY upright cabinet (recently updated with two spinners, yay!), some people likewise fail to recognize them as coin buttons. ;) I still can't decide if I want to use Dollar ($) or Yen (¥) symbols …

@drevil2002 As for the number of buttons, I recommend at least six per player, or, if you have the space, even eight. Apart from being able to map the four-in-a-row button layout of the Neo Geo and Vectrex controllers accurately, you could put additional functions on the excess buttons like pause, screenshot etc.

Me to!

@jodiefoster The point is that neither you nor we know what exactly was changed under the hood which may be the source of problems you won't have with the official image. Only the person who made this custom build knows that, so you should ask them or use the official build.

@stoney66 Thanks for that.

I had a look at those cfg files and they all looked fine.

So I did a completely fresh install of RetroPie.

Tried it out, R-Type controls worked fine.

Then I started adding nice tweaks such as ES Themes etc, and suddenly R-Type had the same problem - P1 right not working unless I re-configure the MAME2003 controls every time.

Not sure what change I applied that caused this, so I'm going to do it all again step-by-step and see when it reoccurs.

My gut feeling is this is a bug in the Pimoroni Picade HAT drivers.
