EKA2L1 VS citra

EKA2L1 (https://github.com/EKA2L1/EKA2L1) is the main Symbian/N-Gage emulator I'm aware of. It works perfectly fine on PC with the games I've tried, but scaling up the already low resolution of the display to PC resolutions, especially with the 3D stuff, is pretty painful.

They're really a web search away. You might be interested in the EKA2L1 emulator and this handy guide from UESP if you feel like playing Shadowkey, but I can't help you with for the game itself.

The EKA2L1 emulator came out more recently so now you can play actual N-Gage games. There’s an UESP guide for getting set up with it which worked for me when I tried it, but idk if it’s been updated or needs updates though. You’ll want to check out these files as well.

CBNK3D is also avaiable on Symbian devices and can be played on EKA2L1 emulator.

If you want to emulate Symbian stuff, I suddest you use the EKA2L1 emu on a 64-bit/ARMv8 Android device for best compatibility. And get a Bluetooth gamepad for the best experience as well :)

EKA2L1 - An Experimental Symbian OS emulator

Doesn't cover 3DS (Citra)

Another wonderful option is to play Nintendo 3DS games with the Citra emulator. They look incredible. I would go so far as to say that if you're a fan of the console then this is the best way to experience its games, even better than on the original hardware. Again use 3840x1200 @ 60 Hz and full SBS. In Emulation -> Configure... -> Graphics -> Stereoscopy set it to "Side by Side". Also increase the renderer internal resolution to as high as your PC can handle (I used "5x Native"). We'll also have to set the display layout for our resolution and aspect ratio. Unfortunately, this has to be done manually. Browse to %APPDATA%\Citra\config and edit qt-config.ini with this in the [display] section:

After some more research, I discovered that the Citra devs discovered and fixed this issue by allowing the Back button to open the in-emulation menu. This fix was added on Jan 22 2023. When I checked the version of Citra available on the Google Play Store on my phone, it was a very old version from May 2021, which is strange because viewing the same Play Store page on my computer shows it was updated in April 2023... maybe your Play Store version is also outdated? If so, the only solution I can think of would be to install the apk from the Citra Nightly github repo.

You might want to consider compiling it on your Mac yourself, rather than trying to download a build, given the situation with MacOS transitioning to ARM. Beyond that, your question is related ton emulation, not ROMs specifically, so if you still need help, ask on related subreddits like r/EmulationOnMacOS and r/CitraEmulator.

I used the one here (you need a github account): https://github.com/citra-emu/citra/actions/runs/5078058438

There have been several recent changes merged for custom textures. Here is one of the pull requests for example: https://github.com/citra-emu/citra/pull/6452. The slow loading you're talking about was only an issue for me if preload custom textures was enabled.
