SkyEmu VS citra

Skyemu has a Web version that's usable on Android. Other than that, I don't think there's any new one.

The autogenerated source code for web.skyemu.app is also open source, and located in the following branch https://github.com/skylersaleh/SkyEmu/tree/gh-pages

I just added a Arm/Intel universal build to the release. You can download it here: https://github.com/skylersaleh/SkyEmu/releases/download/v2/SkyEmu-v2-macOS-universal.dmg

It is possible to make web applications in C++. Here is a web-based Game Boy emulator done in C. But it's a hell of a lot harder than doing it in a language designed to make web applications.

SkyEmu (https://github.com/skylersaleh/SkyEmu)

Despite it being a new emulator, it features high accuracy and compatibility allowing it to play difficult to emulate games that established emulators like mGBA and VBA-M struggle with. On top of accurate emulation. SkyEmu supports the following major features:

SkyEMU, the GB/GBC/GBA emulator project that I have been working on for the last six months was recently able to 100% pass all 1920 of Endrift's GBA suites timing tests. I believe this is the first time this level of timing accurate emulation of the GBA has been achieved and I wanted to share my excitement with the community.

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 maybe your Play Store version is also outdated?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.
