also tekkno parrot and other pc arcade lauchers at some point would be just awesome.

It is missing core for 3DS with opengles. Here is citra mmj with old builds slso for linux (not only for android): https://github.com/SnowZucc/citra-archive?tab=readme-ov-file
i would love to see an zinc-like arcade core for psx based arcade games [like Sony ZN,Namco System 11, Taito FX1 and so on]
maybe it is possible to use one of the ps1 core as a base ?! much like kronos and flycast support arcade roms, it might be great if beetle psx or swanstation can do the same.

Thank you @Duimon .
Last Time i tried mame many of these games were fine but not perfect. And there were unexpected speed issues with lower end Hardware (i donât mean Smartphones or RPI). PS1 Emulation can run on a potatoe or with much lower latency setting or even more demanding stuff like runahead, frame delay if your system has the extra Juice. But i will try current standalone mame and See If anything has changed.
EDIT: i tried Tekken 3 on an i7 7700 which has somewhat good single core performance. the game still has some smaller graphical glitches and some minor slowdown with shitty latency settings (thr. Video on, swapchain 3, No framedelay, GPU hard sync off) . Overall not that great i guess. The Same i7 with Swanstation and beetle psx can run the Game (as PS1 Port) without noticeable glitches with several hundreds fps and no Slowdown even at lowest latency settings. Even when i enable software renderer in both PS1 cores, they are MUCH faster than MAME and are more accurate. Iirc with zinc i had very good emulation more than 20 years ago on a P3 with 1Ghz^^.
I would really like to see some alternative to mame for PSX Arcade. The Guys from flycast and kronos did an awesome job for arcade emulation.
I would really like to see these arcade things getting more often integraded in the cores - especialy 3D arcade systems like the ones based on 3DO and N64 would be absoluly awesome!!! Maybe there are more? 3D Games are often hit or miss with mame, or slow or both, hence that it would be nice to have options, because options are allways nice 
I would like to see the video deinterlacing as used by swanstation gets ported over to other cores with interlaced content. F.e. Games on Beetle PSX and Beetle Saturn can look much better with such a build-in feature. I know i can use deinterlacing shader but i like the integrated solution of swanstation better.
I think that kind of stuff can only be done on hardware-rendered cores, so no Beetle PSX or Saturn. Perhaps it could be done on Beetle PSX HW or Kronos.

i created request in the githubs of the mentioned cores. i think nowadays outputting interlaced is only usefull if you plan outputting to a 15khz crt. otherwise i donât see any point of keeping interlaced video signals arround in 2025. standalone emus mostly have such a feature. i get it with the RA deinterlace-shader but if you deinterlace that way, all stuff including 240p gameplay and not only the interlaced parts (like menus f.e.) gets deinterlaced!?

Weird timing since just a few days ago I added the internal bob deinterlace option to both Beetle Saturn and PSX.

Swanstationâs interlacing disable toggle works with itâs software renderer too (which is based on Mednafenâs.) Iâm not sure if it works using per game hacks or what though. The only game I tried that it didnât work on was the bonus 60FPS Ridge Racer Turbo disc that came with R4.
With interlacing disabled in Swan, it looks like youâre running the games at 480p with no deinterlacing artifacts.

@Awakened I thought that behavior was quiet an archivement and found it sad not more cores allow this approach.
Great!!! Are these Bob Filter work Like the one in Swanstation? I Mean it deinterlaces only interlaced content but passes on non-interlaced stuff like 240p?
I do know that deinterlace.slang (the shader) only activates beyond a certain resolution, so pure 240p content is fine. There are, however, several PS1 and Saturn games that do both resolutions and keep changing them. For static images in 480i, the aforementioned shader doesnât do a commendable job, so it would be wiser to use a crt shader with a better deinterlacing option integrated.
Regardless, with the new option sonninnos implemented, that may be all in the past, fortunately.

Nice. Is this on the online updater?
For the reminder, tekken 3 psx is far from being a 1:1 port of its arcade version. You are comparing apples and melons here. Are those minor slowdowns possibly something happening on real hardware that can be removed by increasing the emulated cpu clock ?
Back to the current subject, i added Kronos standaloneâs deinterlacing filters to the libretro port, theyâll be available from the online updater later today.

The Showdown comes from Mame not able to Run fullspeed. Including audio dropouts even with very relaxed latency settings for Video and audio. I know that the port it is not directly compareble but not keeping 60 FPS at Minimum with mame but getting hundreds of FPS with PS1 cores with seemingly better accuracy seem a big Performance imrovement/difference to me. Mame is slow and not even accurate for psx arcade. I think itâs because hle vs lle ?
Cool i will try the Filter asap.
Well, tekkenâs namco system 12 is not a psx, itâs really more of a playstation 1.5 with several upgraded components (new cpu is 3 times the frequency of psxâs), and i think MAME is actually using HLE emulation for that cpu (dynarec). Itâs kind of like comparing a dreamcast/naomi1 with a naomi2.
iirc the only arcade board really identical to the psx is the zn-1.

@BarbuDreadMon thank you for the very deep information about the psx arcade stuff. I am Not sure and i will not trying out every psx arcade system with every game - since there is a good number of them (i am mainly in the taito Boards) but in General i found these systems to be more buggy and slow than i would expect. And i still think it would be a nice addition to RA getting something more accurate and faster so that it can be used by more people with weaker devices like handheld, older Laptops/Pcs or even Smartphones. If itâs not something the majority of the community would like to see i can really understand it. Arcade in General is somewhat niche and developing cores is surely alot of work and it seem there is not a big Potential benefit from it Performancewise, as i know now after your Kind answer. It was just and idea/wish for myself. But i still enjoy talking about it very much! Thank you for the nice conversation, you are a very good member and its allways a great pleasure talking with you!!!
its somewhat funny that Naomi Emulation runs better now, than psx arcade or Sega ST-V . For the later there is Kronos which is a godsend⌠But thatâs how Emulation works sometimes i guess.

Greetings. Could it be possible to add âApple IIâ core into RetroArch (and RetroArch Android) ? There seems to be an open source Apple II emulator on GitHub:
And it will be even better if Apple II core on RetroArch, supports RetroAchievements as well.

I have mentioned this before in the past but i would like to repeat it again.
The core options.opt system needs to work in the same way as regular overrides do.
Right now they donât. If i change one option for a certain game and save it as a âgame.optâ it also saves all the other options that i didnât change in the .opt file. Which means if i change something else in my general âcore.optâ to affect all games, that particular game will still have the old option saved so it wonât be affected.
With overrides, ONLY the changed option is saved and it reads all the others from the default.cfg. This way if i change something else in the default core.cfg, it will affect all games, even the ones that have their own overrides for other options.
If the .opt files can work like overrides do, it would be a massive upgrade for RetroArch.
